Anti-wet-slippery resin composite material

Abstract

The invention discloses an anti-wet-slippery resin composite material including, by weight, 60-85 parts of modified terpene resin, 12-20 parts of aryl polysulfone resin, 10-20 parts of alicyclic hydrocarbon resin, and 4-10 parts of a compatibilizer. The composite material is a directly-inner-adding-type reagent and is used for overcoming problems in a scheme of using white carbon black and solution polymerized styrene-butadiene rubber, which needs a large number of adjustment operations and generates huge fluctuation. The composite material is added with other small materials during mixing andis free of adjustment on formula and process. The composite material can significantly increase the anti-wet-slippery performance of vulcanized rubber and improve driving safety of rubber products, especially tyres. In addition, a preparation method employs easy-to-obtained raw materials, has low cost and is simple in processes.

Description

technical field [0001] The invention belongs to the technical field of novel fine chemical materials, and in particular relates to an anti-wet skid resin composite material. Background technique [0002] Tires are a very important part of the safe driving of cars. Accidents caused by tires are common and the consequences are very serious. In recent years, people's requirements for car safety, comfort and energy saving have been increasing year by year. The new European regulatory labels have been Enforced in 2012, the main content is to limit the three basic performances of tire treads: anti-wet skid, rolling resistance and noise as the hard indicators of passenger car tire replacement tires, and wet skid resistance is one of the mandatory performances , it can be seen that it is one of the most important performances to ensure the safety of tires, and it is a key indicator to measure the driving safety of a car during use, especially in complex wet and rainy road conditions...

AI Technical Summary

Problems solved by technology

[0003] For the research on the improvement of tire wet skid resistance, more and more attention has been paid in the past two decades, but at the same time it is full of challenges, so it has not been systematically solved so far. At present, the improvement of tire wet skid resistance is mainly through Adding a large amount of silica and using solution-polymerized styrene-butadiene rubber are two options. Due to the unique hydrophilic characteristics of silica and the influence of self-agglomeration, adding a large amount of silica will inevitably bring about a great increase in processing difficulty. Bringing a great increase in equipment load and energy consumption; using solution-polymerized styrene-butadiene rubber to replace the main rubber, it is necessary to make a large adjustment to the overall formula and process parameters, which limits its promotion and use to a certain extent. Therefore, in the overall On the premise that the formula system, production equipment, and process parameters remain stable, the use of anti-wet skid additives directly added to improve the wet skid resistance of tires has become a favored and ideal option for tire manufacturing workers. An anti-wet skid resin composite material is developed under this technical background
