Problems solved by technology

[0005] The above-mentioned prior art scheme has the following defects: the above-mentioned scheme only enhances the heat resistance of the glue by adding elastic glue, but the elastic glue itself is a kind of glue preparation, and its heat resistance is limited. Therefore, the elastic glue is resistant to glue. Insufficient boost of heat

Abstract

The invention relates to a glue and a preparation process thereof, comprising the following components in parts by weight: 75-95 parts of polyurethane prepolymer emulsion, 10-20 parts of soybean protein fiber modified emulsion, 4-8 parts of fly ash, lignin 3-6 parts of sodium sulfonate, 2-5 parts of Polygonatum powder, 1.5-3.5 parts of flame retardant and 0.5-2 parts of antioxidant; the soybean protein fiber modified emulsion is soybean protein fiber-nano titanium dioxide-organic silicon emulsion; The preparation process specifically includes the following steps: S1. Main ingredient mixing: first add soybean protein fiber modified emulsion to the polyurethane prepolymer emulsion and stir evenly, the stirring temperature is 25-35°C, and the stirring time is 2-4min; S2. Accessory materials Addition: Add sodium lignosulfonate, Polygonatum powder and fly ash to the emulsion prepared in S1 and stir evenly, the stirring temperature is 25-35°C, and the stirring time is 1-3min; S3. Finished product preparation: Add to the emulsion prepared in S2 Add the flame retardant and antioxidant and stir evenly, the stirring temperature is 30-40°C, and the stirring time is 1-2min, and the finished glue is made. The invention has the effect of improving the heat resistance of the glue.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a glue and a preparation process thereof. Background technique [0002] Glue is an intermediate that connects two materials, mostly in the form of water, and belongs to the category of fine chemicals. There are many types of glue, which are mainly classified by adhesive, physical form, hardening method and adherend material. Common glues include instant glue, epoxy adhesive, anaerobic glue, UV glue, hot melt adhesive, pressure sensitive adhesive, latex, etc. [0003] Since various glues on the market have the defect of poor heat resistance, how to improve the heat resistance of the glue so that it has a wider application prospect is an urgent problem to be solved in glue production. [0004] At present, the Chinese invention patent with the notification number CN102002330B discloses a glue, which is composed of the following raw materials in parts by weight: 3000-6000 parts o...
