Recently, natural rubber (NCR) - nanometer clay industrialization key technology assessments held in haikou, by xue, ShuXingTian, Jian tin higher three Chinese academy of engineering and rubber elastomer industry experts through field evaluation expert review committee believes: the successful development of the project - nanometer clay natural rubber (NCR) complete sets of technology and production line, the key technology in the international leading level, agreed to by identification.

Since 2017, a scientific research technology jointly completed by sealant group and Beijing university of chemical technology has been successively applied in fengshen tire, linglong tire, zhongce rubber and other enterprises, so that the life of existing engineering tire products can be increased by more than 20%.

Technological innovation -- promote the improvement of the quality of natural rubber

"With the rapid development of China's rubber industry, China has become a major consumer and importer of natural rubber, the downstream industry of natural rubber quality, performance requirements are increasingly high. Hai jiao group science and technology research and development center rubber processing chief engineer huang qianqian told reporters, due to geographical and processing process differences and many other factors, domestic rubber has a natural shortcoming, some "high-precision" products with rubber is still dependent on imports.

In 2014, sealant group and Beijing university of chemical technology formally signed a strategic cooperation agreement to jointly develop high-performance nano-clay natural rubber, aiming to reverse the passive situation of domestic rubber, use domestic rubber in the rubber industry "knife edge", and better play the role of natural rubber strategic materials.

"For a long time, the modification and upgrading of domestic rubber are mainly focused on the innovation of processing technology and chemical modification. The key technology of 'nano-clay natural rubber' project is innovative, and nano-clay is introduced into natural rubber for the first time in the world." Huang qianqian told reporters that the core technology of the project is to adjust and improve the structural system of natural rubber, an innovative way to improve the quality of natural rubber modification.

Introducing "three kinds of resources" -- innovation to enhance competitiveness

Innovation-driven development is an important strategy put forward in the 19th CPC national congress. The 19th national congress of the communist party of China (CPC) pointed out that innovation is the primary driving force for development and the strategic support for building a modernized economic system. We will promote the transformation of scientific and technological achievements through the establishment of an innovation system with enterprises as the main body, market as the guidance and in-depth integration of industry, education and research.

In recent years, gelatine group has made bold investments and experiments in innovation. In 2015, seagao group and tsinghua university jointly established China advanced rubber industry alliance with well-known enterprises, universities and research institutes engaged in rubber production, research and development and application in China, and set up a r&d and innovation platform for high-end natural rubber and related composite materials such as national defense natural rubber. In recent years, through cooperation, the member units of the alliance have complemented and united with each other in such aspects as basic research on natural rubber, development of new products, market promotion and application, and recycling and reuse of waste rubber products.

Some of the research results of the cultivation factors in cooperation with hainan university on the ozone aging resistance of natural rubber have been applied in the actual production. Ministry of industry and information technology "natural rubber industry green supply chain system construction" project, haikou "sea tooling rubber products and materials testing public service platform" project have been approved to land in the sealand group.

The secretary of the party committee, chairman of the board of directors Wang Renfei rubber group, said the will deepen the reform of the supply side structural glue group, the increasing introduction of intellectual resources, capital resources and industrial resources, promote the enterprise sustainable innovation, technology constantly breakthroughs, to speed up the pace of industrialization, leading the Chinese natural rubber industry in the world of the two rubber stand tide in the market.

Industrialization - wide application of products

"We used to focus on the process improvements, like adding chemicals to improve the quality of the glue. Generally speaking, in the past, we only studied the improvement of quality in the treatment of 'table', not in the treatment of 'origin'. Huang qianqian told reporters, "nano-clay natural rubber" technology from the rubber molecular chain and other micro-structure to consider, to improve the quality of natural rubber found a cure for the effective way. "It's like when we build a house, we focus on supporting the skeleton, not just adding bricks and tiles." "Huang explained.

In addition, this technology has good compatibility in the implementation process. It does not need a large investment, does not need to the original processing plant equipment "down to the beginning", just on the basis of the existing process to add some necessary process links, process environment, conducive to the promotion of industrialization process.

In the process of promoting industrialization, sealand group has established a quality control system in jinlin processing branch to ensure the stability, safety and reliability of product quality by strengthening the training of front-line employees and implementing the production process and technical regulations. In 2016, the two parties completed the construction of 10,000-ton production line and produced qualified products. The product technology solved the problem of high moisture content of clay glue and difficulty in dehydration.

Zhang liqun, dean of school of materials, Beijing university of chemical technology, changjiang scholar and chief scientist of the national 973 project, introduced that nano-clay natural rubber can be widely used in high-end rubber products such as aircraft tires and heavy machinery tires because of its unique nano-chip layer resistance to cutting and wear. Since 2017, it has been successfully applied in fengshen tire, linglong tire, zhongce rubber and wuxi baotong belt industry, so that the service life of existing tire products can be increased by more than 20%.
