Embodiment Construction

[0017] The present invention will be further elaborated below, and the product formulation and its preparation process are very clear to those skilled in the art.

[0018] Free radical silicon molecular polymer materials include styrene-isoprene block copolymer, maleic rosin, engine oil, antioxidant additives and organic silicon additives. The weight ratio of the components is as follows:

[0019]

[0020] Styrene-isoprene block copolymers belong to thermoplastic elastomers and can be used as adhesives and sealing materials. Its chain structure, film-forming conditions and post-treatment methods can all affect its performance.

[0021] The silicone additive can be a silane coupling agent, whose general formula is Y(CH2)nSiX3, where n=0~3, X is a hydrolyzable group, which can often be chlorine, methoxy, ethoxy, methyl Oxyethoxy, acetoxy, etc., Y is an organic functional group, which can be vinyl, amino, epoxy, methacryloyloxy, mercapto or ureido, etc.

Abstract

The invention relates to the technical field of automobile tire protection material manufacture, in particular to a bulk density (BD)-free radical silicon molecule polymeric material capable of adapting to tire self repair and a production method of the BD-free radical silicon molecule polymeric material. The free radical silicon molecule polymeric material is characterized by comprising styrene-isoprene segmented copolymers, maleated rosin, engine oil, antioxidant additives and organic silicon additives. The material preparation process comprises the following steps that: raw materials are proportionally mixed and are then put into a reaction kettle, the temperature is raised, the pressurization is carried out, the materials are sufficiently stirred, the temperature is lowered, and the materials are discharged. Compared with the prior art, the free radical silicon molecule polymeric material provided by the invention can be used in a temperature range being 0 to 20 DEG C, the regional disparity does not exist in the use process, the physical and chemical properties are stable, after the free radical silicon molecule polymeric material is coated on the tire, the tire can realize the self repair after being pierced, the tire repair and the tire replacement are not needed, the tire also has the functions of noise reduction, shock absorption, energy saving, blasting prevention and leakage prevention, the temperature inside the temperature is reduced, and the service life of the tire is prolonged.

Description

[technical field] [0001] The invention relates to the technical field of manufacturing automobile tire protection materials, in particular to a high molecular polymer capable of automatically compounding the inner surface of tires at normal temperature. [Background technique] [0002] In recent years, with the rapid development of social economy and municipal construction, people have put forward more stringent requirements for automobile driving safety. [0003] Car tires are one of the important parts of the car. They bear the weight of the car and together with the car suspension buffer the impact of the car when it is driving. Because the tire directly contacts the road surface and rubs against the ground during driving, it is easy to cause tire wear , Even due to the sharp and hard objects on the ground, the danger of tire bursting is caused, so the protection of automobile tires is particularly important. [0004] At present, the safety protection of automobile tires ...
