Abstract

The invention discloses a styrene volatilization inhibitor based on a cholesterol derivative, and a preparation method thereof, wherein the styrene volatilization inhibitor comprises, by weight, 20-70parts of a cholesterol derivative, 0-5 parts of paraffin, and 30-80 parts of a diluent. The preparation method comprises: uniformly mixing a cholesterol derivative, paraffin and a diluent, and filtering. According to the present invention, the styrene volatilization inhibitor constructed based on the cholesterol derivative is added to a unsaturated resin, and the styrene volatilization inhibitorcan float on the surface and form a film during the resin standing and curing, such that the volatilization rate of styrene can be significantly reduced while the interlayer adhesion of the unsaturated resin product cannot be affected, the good leveling property can be achieved, the appearance of the product cannot be affected, and the weather resistance is good.

Description

Technical field [0001] The invention relates to the field of chemical additives, in particular to a styrene volatilization inhibitor based on cholesterol derivatives and a preparation method thereof. Background technique [0002] Unsaturated polyester resin has good comprehensive physical properties, convenient processing, and low cost, so it is widely used in rail transit, wind power energy, construction and home decoration, automobile interior and exterior decoration, shipbuilding, coatings and other national economic fields. Unsaturated polyester resin contains 25-50% styrene, and styrene is volatile, which is easy for customers to lose materials and cause waste. More importantly, styrene has a pungent odor and is a potential carcinogen, which will cause a large smell in the production workshop, serious environmental pollution, and seriously endanger the physical and mental health of workers. For this reason, downstream customers have gradually increased their demand for low ...
