Problems solved by technology

[0003] However, the method of reducing TVOC through chemical reaction is often only aimed at one factor that produces TVOC, and cannot solve the TVOC problem produced by various factors at the same time; physical adsorption does not have specific selectivity, and can adsorb all small molecules produced, but Adding molecular sieves to prepare low TVOC polypropylene materials has a disadvantage: no oily substances can be added to the system

Abstract

The invention discloses an application of polysiloxane silicon oil in a low-emission polypropylene composition. The polysiloxane silicon oil comprises one or more of hydrogen type polysiloxane, hydroxy polysiloxane, methyl polysiloxane, vinyl polysiloxane, amino polysiloxane, epoxy polysiloxane and methoxy polysiloxane silicon oil, and the total volatile organic compounds in the low-emission polypropylene composition are 20.4-48.1mugC / g. The polysiloxane silicon oil which forms a uniform film on the surface of talcum powder can block the volatilization of a polypropylene material, so the air pollution in a vehicle is reduced.

Description

technical field [0001] The invention relates to the application of polyorganosiloxane silicone oil in low emission polypropylene composition. Background technique [0002] Because the car compartment is often in a closed state, the internal air quality is often affected by free formaldehyde, alkanes, benzene, toluene and other organic compounds (TVOC) produced by interior products such as leather seat covers or cloth seat covers, which have adverse effects on the human body . In order to reduce the TVOC content in the material, it is necessary to control the source of raw materials, processing technology, additives, etc., or add substances that can react with these small molecule volatile substances to form a larger molecular weight, which is less volatile and can be stably stored in the material. Compounds that are not easily volatile, so as to achieve the purpose of reducing TVOC. Patent application WO2007052074-A2 discloses a palladium-doped molecular sieve to adsorb VO...
