Abstract

The invention discloses a strong adhesive. The strong adhesive is prepared from the following components in parts by weight: 27-39 parts of 2,2-dimethylolpropionic acid, 15-28 parts of crocetin-dimethylester, 23-34 parts of toluene diisocyanate, 12-29 parts of ethyl palmitate, 18-30 parts of isoamyl acetate, 8-21 parts of 1,1-diethoxy-3-methyl-butane and 45-60 parts of O-ethyl xanthogenate ethyl propionate. The strong adhesive has the beneficial effects of high drying speed, long adhesion holding time, good operability, strong adhesive strength, good initial cohesiveness, heat resistance, water resistance and aging resistance.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a strong adhesive. Background technique [0002] The concept of adhesive: Adhesive is a substance that firmly bonds various solid materials together by interfacial action (chemical force or physical force). It is also called adhesive or adhesive, referred to as "glue". [0003] Adhesives are widely used in various fields of the national economy, such as construction, packaging, aerospace, aviation, electronics, automobiles, machinery and equipment, medical and health care, and textiles. [0004] However, the currently used adhesives have long drying time, short bonding retention time, poor heat resistance, water resistance, and aging resistance. Contents of the invention [0005] The main technical problem to be solved by the present invention is to provide a strong adhesive with fast drying, long bonding time, good operability, strong adhesive force, good initial tack, heat resistanc...
