The expert group expansion meeting of the rubber auxiliary Professional Committee of China Rubber Association in 2019 was held in Hebi from May 7 to 9. All experts and representatives of the board of directors, as well as two experts, Linglong tire and shuangqian tire, attended the meeting with 31 participants in total. The meeting was presided over by Secretary General Gao Bo, attended by leaders of Hebi City and Heshan District government, and made a detailed introduction to Baoshan chemical industry park. According to the resolution of Guangzhou Council in March, the meeting discussed the task of industry technology level in 2019, and the representatives at the meeting expressed their views on the industry technology involved. The minutes of the meeting are as follows:
1、 Preparation and revision of relevant standards of rubber additives industry in 2019
1. Accelerator TBBS product association standard
In 2018, the standard working group of accelerator TBBS Association completed the preparation of the first draft of the standard, and the Secretariat of the special committee put forward the direction of revision. It is hoped that the standards of TBBS association should fully reflect the technical indicators of product efficiency and better promote the development of product quality to a high level. According to the preliminary test conducted by the National Engineering and Technology Center for rubber additives, the influence of the purity of accelerator TBBS on the curing curve is still small. Experts at the meeting agreed that there is no good technical support for judging the curing promotion effect of accelerator TBBS by the curing curve. Director Dong of shuangqian tire published their recent application research results, which showed that different particle size distribution of accelerator TBBS had a greater impact on the performance of rubber compound, which may be an effective way for tire enterprises to identify the performance of accelerator products.
The expert group agreed that the Secretariat, together with the working group on TBBS standards, should hold a special meeting as soon as possible to study the effective technical indicators of accelerator promoting the vulcanization reaction performance, carry out the verification test and laboratory comparison test, and finally complete the formulation of "TBBS Association standard for rubber accelerator".
2. Three high is product association standard
In 2017, the formulation of the "high thermal stability insoluble sulfur" association standard was not completed due to the difficulty of the effectiveness of the high dispersion test method. Before the meeting, the National Engineering and technology center of rubber additives carried out two repeatability tests on the dispersibility test of density deviation method for is. The preliminary conclusion is that the reproducibility of density deviation method test data is poor and there are many influencing factors, which needs further exploration. Experts from tire enterprises put forward suggestions on the dispersion of free sulfur and is particle size distribution.
The representatives of the expert group agreed to open the meeting of is association standard working group as soon as possible, especially invite experts from tire enterprises to participate in the standard working group, discuss and verify the method of multi index relative evaluation of is dispersion, and hope to form a consensus and strive to complete the high-level Association standard work.
3. Association standard for evaluation system of "excellent suppliers in rubber additives industry"
The representatives of the expert group agreed that the Secretariat should issue a document and set up the working group for the preparation of standards of the association on a voluntary basis, and invite at least three experts from tire enterprises to participate in the working group. According to the evaluation system of "excellent natural rubber supplier", the first draft of the standard is prepared, and then the Secretariat submits the document to the technical and Economic Commission of the general assembly for the preparation and approval of the standard.
4. "Evaluation system for cleaner production of rubber additives industry" issued by MIIT
The preparation of the standard and relevant PPT and other materials have been completed. At present, the Ministry of industry and information technology is organizing experts to review, waiting to pass the review and release the standard.
5. Open a green channel for enterprises to initiate the preparation and revision of new products, new technologies, new equipment and other standards
With the continuous increase of association standards, and the Association standards are more close to the industry and more reflect the technical level of the industry, the efficiency of the association standard system will be increasingly expanded. In order to better serve member enterprises, we have opened the green channel for initiating declaration of association standards throughout the year. We welcome member enterprises to initiate declaration of association standards for new products, new technologies, new equipment, etc. according to the needs of enterprises. We will organize experts to demonstrate the application materials, and to demonstrate the Association standards that can reflect the technical level of the industry and better promote the continuous development of industry products and technologies We will actively apply to the technology and Economic Commission of cfta, strive to build a standard system of Rubber Additives Association, and a complete standard system with national standards, bank standards and enterprise standards.
2、 A tentative idea of self-discipline in the industry
1. Review of green rubber additives Enterprises
The Secretariat will organize experts to formulate relevant implementation plans as soon as possible and submit them to the general assembly for approval once the "cleaner production evaluation system for rubber additives industry" is issued by the Ministry of industry and information technology. According to the unified leadership of the Federation, carry out the review and release of "green enterprise of rubber additives".
2. Review of "excellent suppliers of rubber additives industry"
Wait for the release of the association standard of "excellent supplier evaluation system of rubber additives industry", then the special committee of rubber additives will organize the review according to the standard, and report to the Federation for approval, and then officially release it at the annual Rubber Conference.
3. Self discipline activities of high-end is products industry
Wait for the release of high-end is product association standard, then according to the characteristics of the standard, put forward specific industry self-discipline implementation plan, carry out the industry self-discipline activities of the product according to the implementation plan, so as to promote high-end is products to move forward to the world advanced level.
4. industry self-discipline activities of accelerator TBBS products
Wait for the release of accelerator TBBS product association standard, then according to the characteristics of the standard, put forward the specific industry self-discipline implementation plan, carry out the industry self-discipline activities of the product according to the implementation plan, and promote the quality of a large number of accelerants to the direction of user expectations.
