Embodiment 1

[0019] A method for preparing an organic phosphating flame-retardant automobile wear-resistant material, comprising the following steps:

[0020] (1) Take 1 part by weight of calcium ricinoleate, add it to 7 times the weight of absolute ethanol, stir evenly, add 5 parts by weight of trimethylolpropane, and keep stirring at 70°C for 20 minutes to obtain alkane base alcohol dispersion;

[0021] (2) Take 2 parts by weight of ammonium polyphosphate, mix with 4 parts by weight of oleic acid, heat and stir at 60°C for 1 hour, mix with the above-mentioned alkyl alcohol dispersion, add 0.13 parts by weight of sodium methoxide, and send it to Into the reaction kettle, feed nitrogen gas, heat and stir at 95°C for 30 minutes, discharge the material, and cool to normal temperature to obtain phosphating lubricating ester;

[0022] (3) Take 2 parts by weight of tetrakis hydroxymethyl phosphorus sulfate, add it to tetrahydrofuran which is 4 times its weight, stir evenly, add 0.8 parts by we...

Abstract

The invention discloses a preparation method of an organic phosphatizing flame-retardant automobile anti-abrasion material. The preparation method comprises the following steps of performing organic treatment on talcum powder, and mixing and crosslinking with aminating lubricating ester, so as to effectively disperse the talcum powder into each polymer matrix, effectively reduce the agglomeration, and improve the stability and strength of finished material; by adding the ammonium polyphosphate, the talcum powder and the like, the good fireproof and flame-retardant properties are realized; by mixing trimethylolpropane and oleic acid, the obtained esterification material has good lubricating property, the compatibility between raw materials is improved, the anti-abrasion property of the finished material is improved, and the esterification material is suitable for being used as the automobile anti-abrasion material.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a method for preparing an organic phosphating flame-retardant anti-wear material for automobiles. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in the industry and is one of the common polymer materials; polypropylene has good chemical stability, except that it can be corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to various other chemical reagents, but low The molecular weight of aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften and swell polypropylene, and its chemical stability increases with the increase of crystallinity, so polypropylene is suitable for making various chemical pipes and fittings, anti-cor...
