Abstract

The invention discloses waistcoat bag dispensing glue water, which is characterized by being prepared from the following raw materials in parts by weight: 20 to 30 parts of main body polymers, 20 to 50 parts of tackifiers, 10 to 50 parts of plasticizers, 1 to 5 parts of filling agents, 0 to 3 parts of silane coupling agents and 1 to 5 parts of antioxidants, wherein the main body polymers are selected from ethylene-vinyl acetate copolymer and styrene-butadiene segmented copolymers or mixtures of the ethylene-vinyl acetate copolymer and the styrene-butadiene segmented copolymers. The preparationmethod of the dispensing glue water is simple; no harmful substances are discharged in the preparation process; no solvent is used; the product belongs to an environment-friendly product. In addition, the waistcoat bag bonding effect of the glue water is good; the curing speed is high; the initial viscidity is high; no foreign smell exists; good anti-aging effect, thermal stability and weather resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of glue preparation methods, in particular to a vest bag dispensing glue and a preparation method thereof. Background technique [0002] The industry divides glue into animal glue, vegetable glue, inorganic and mineral, synthetic elastomer, synthetic thermoplastic material, synthetic thermosetting material, thermosetting, thermoplastic material and elastomer composite according to the properties of the adhesive. More common AB glue, instant glue, anaerobic glue, UV glue and some special glue. [0003] During the use of glue, the first thing to determine is the glue ratio. For example, AB glue, mix the main agent and the hardener at a ratio of 1:1, and apply the glue to the object after ensuring that the surface of the object to be coated is clean. It is best to control the temperature at sixty to ninety degrees. Instant glue often encounters the problems of whitening, brittleness and aging resistance duri...
