Glue for building material with high adhesive force

Abstract

The invention discloses glue for a building material with a high adhesive force. The glue comprises the following raw materials in parts by weight: 60-80 parts of water-borne epoxy resin, 15-21 parts of a gypsum powder compound, 12-20 parts of sodium alginate, 30-40 parts of water-based polypropylene resin, 25-35 parts of a filling agent, 2-4 parts of hydroxyl silicone oil, 1.5-2.5 parts of disproportionated rosin, 1-2 parts of palmitic acid, 2-4 parts of stearic acid, 4-10 parts of glycerinum, 1-2 parts of antioxidant and 120-160 parts of water. The gypsum powder compound is prepared according to the following processes: mixing epoxidized soybean oil, polylactic acid, gypsum powder, tetradecandioic acid and stannous octoate, stirring while raising temperature, and then raising temperature, stirring and cooling, thereby acquiring a gypsum powder compound. The glue has excellent mechanical properties and high adhesive force, is difficult to reel and fall off, contains no formaldehyde, is capable of effectively removing harmful gases in indoor air, is capable of increasing the indoor air quality and is more healthy and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of glue, in particular to a glue for building materials with high adhesion. Background technique [0002] The glue used in the construction industry is different from ordinary glue, which requires high adhesion and a long enough sticky time. There are two production methods for construction glue currently used in the market. One is that the manufacturer directly packs the liquid produced by chemical materials such as water-based epoxy resin and water-based polypropylene resin and puts it on the market; the other is that the manufacturer puts PVA, EVA, etc. , CMC and other high molecular polymer powders are processed into construction glue and put on the market in sub-packages. These two glues contain toxic substances such as formaldehyde, ammonia, and preservatives. They are not environmentally friendly, and the quality of the glue is low. The prepared putty has poor adhesion, easy to curl and fall off. C...
