Environment-friendly curtain adhesive for hair product and preparation method thereof

Abstract

The invention relates to an environmental-friendly curtain adhesive for a hair product and a preparation method thereof. The environmental-friendly curtain adhesive for a hair product is compatibly dissolved and synthesized by the following raw materials in parts by weight: 0.05 part of alcohol-soluble polyurethane adhesive b, 0.04 to 0.15 part of sugar ester, 0.05 to 0.25 part of rosin, 0.05 to 0.4 part of curing agent of alcohol-soluble polyurethane adhesive, 0.01 to 0.08 part of sodium persulfate and 0.15 to 0.75 part of absolute ethyl alcohol. In the preparation method, the thermal decomposition type sodium persulfate is used as the initiator to avoid pollution caused by a decomposition product remained in the adhesive when the organic peroxide is used as the initiator; the high-temperature polymerization replaces the low-temperature polymerization to reduce the energy consumption; the conversion rate of the polymerization reaction is improved and the quantity of the recovered monomer is reduced; the physical degasification and the chemical degasification are combined, so that the degasification time is shortened and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of the mutual intersection of chemical technology and biological technology, and particularly relates to an environmentally friendly curtain glue for hair products and a preparation method thereof. Background technique [0002] At present, the curtain glue of hair products is mainly solvent-based resin adhesive, which has the following defects (1) most of the curtain glue is not strong enough to bond the wig, which is easy to cause hair loss; (2) after the wig uses the curtain glue, the curtain edge of the wig It is relatively hard and not soft enough; (3) the composition of traditional curtain glue cannot meet the requirements of environmental protection. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide a kind of environmentally friendly curtain glue for hair products with strong cohesion, lasting effect, no...
