Problems solved by technology

[0002] Thermoplastic elastomers, such as styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene-butylene-styrene block copolymer (SEBS), etc., are prone to adhesion and agglomeration at room temperature , which affects subsequent use, so in the past, calcium stearate was used as anti-adhesive agent, such as anti-caking agent and anti-adhesive; however, when calcium stearate products are used as anti-adhesive It is easy to pollute and damage the molded catalyst, leading to the failure of the molded catalyst. Therefore, it is inevitable to develop pure organic matter that does not contain metal ions or elements as an anti-sticking agent for elastomers, that is, rubber.

Abstract

The invention provides a thermoplastic elastomer anti-sticking agent, and a preparation method and application thereof. The thermoplastic elastomer anti-sticking agent is prepared from, by mass, 5-50%of fatty acid amide or fatty acid ethanolamide, 5-50% of a solvent and 0-90% of water; the fatty acid amide or the fatty acid ethanolamide is prepared by reacting fatty acid with an amine compound, and the number of carbon atoms on a fatty acid carbon chain is 12-22; and isopropanol, ethanol or methanol is adopted as the solvent. The anti-sticking agent takes amide substances as a main material,can be dissolved in a xylene solvent, can be dissolved or dispersed into a whole with an elastomer in the solvent, can form a solid film-shaped object after being dried to achieve an anti-sticking effect, and does not influence the production and molding of the elastomer; and the anti-sticking agent is an organic matter composed of three elements of C, H and O, does not contain metal elements or metal ions, and does not generate chemical action with any catalyst or heavy metal ion treating agent.

Description

technical field [0001] The invention relates to the technical field of elastomer anti-adhesive, in particular to a thermoplastic elastomer anti-adhesive agent and its preparation method and application. Background technique [0002] Thermoplastic elastomers, such as styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene-butylene-styrene block copolymer (SEBS), etc., are prone to adhesion and agglomeration at room temperature , which affects subsequent use, so in the past, calcium stearate was used as anti-adhesive agent, such as anti-caking agent and anti-adhesive; however, when calcium stearate products are used as anti-adhesive When it is used, it is easy to pollute and damage the molded catalyst, leading to the failure of the molded catalyst. Therefore, it is inevitable to develop pure organic matter that does not contain metal ions or elements as an anti-sticking agent for elastomers, that is, rubber.
