Description

A kind of automotive trim seat uses noise reduction wax and preparation method thereof

Technical field

The invention belongs to chemical field, and in particular to a kind of automotive trim seat uses noise reduction wax, further relates to the noise reduction wax Preparation method.

Background technology

Paraffin is one kind of refinery products, is one kind of mineral wax, is also one kind of pertroleum wax.Paraffin is that solid-state is high The mixture of level alkane, the molecular formula of main component is CnH2n+2, wherein n=17~35.Key component is linear paraffin, also There is the monocyclic naphthenes of a small amount of alkane with indivedual side chains and belt length side chain；It is mainly n-docosane in linear paraffin (C₂₂H₄₆) and positive octacosane (C₂₈H₅₈).It is from the lube cut obtained by crude distillation through solvent refining, solvent dewaxing or Be made slack wax through wax freezing and crystallizing, squeezing dewaxing, then through solvent deoiling, it is refined obtained by sheet or acicular crystal.According to whether Poisonous to be divided into food-grade (food-grade and packaging level, the former is excellent) and technical grade, food-grade is nontoxic, and edible, technical grade is not edible With, but purposes is wide, available for higher fatty acids processed, higher alcohol, match, candle, waterproofing agent, ointment, electrically insulating material, lubricant Deng.

White oil, alias paraffin oil, white oil, mineral oil are, by the mixture of refining liquid hydrocarbon obtained by oil, predominantly to satisfy The cycloalkane and alkane mixture of sum, crude oil are obtained through normal pressure and vacuum fractionation, solvent extraction and dewaxing, hydrofinishing. Food industry can be used as fruit glaze agent, China《Food additives use sanitary standard》(GB2760-2014) provided in：White oil can use In other candies in addition to gel-based candy, fresh egg, maximum usage amount is 5.0g/kg；Other use reference：It is stripped as bread Agent, baking plate corrosivity is small, and offending smell is not produced；As food machinery lubricant, not etching mechanism；In addition also it can use To extend water fruits and vegetables, the Storage period of can.

Silicone grease is the oily thick inorganic thickening agent based on refining artificial oil, and is added added with structural stabilizing agent, anticorrosion Agent is refined to be formed, and with good waterproof seal, waterproof, solvent resistance and creep resistance energy, does not corrode metal, has with rubber Well adapting to property, for bathing device, sealing ring, the waterproof sealing of electric industry and lubrication.

Paraffin, white oil and silicone grease can be used as lubricant, such as noise reduction wax, can be reduced froth pulp and be rubbed with metallic framework The abnormal sound of wiping, therefore widely used in automotive trim.But the noise reduction wax on existing market is typically dissolved using organic solvent, Volatilization produces harmful components.As the improvement of people's living standards, to vapour environment inside car requirement also more and more higher, country also puts into effect Corresponding VOC emission standard and requirement.In order to meet the VOC standards and low-carbon emission of customer and country, it is badly in need of exploitation one Plant water-based lubricant, the water-based emulsion made by paraffin white oil and silicone grease etc..
