preparation example Construction

[0023] The preparation method of multi-purpose glue: 1) Synthesize polyether prepolymer; 2) Bake the filling material at 125-135°C for 2.8-3.2h, lower to normal temperature, discharge, add polyether prepolymer, additives, 50 Vacuum at -60°C for 0.8-1.2h, mix and stir for 0.8-1.2h to obtain the product.

[0024] The preparation method of multi-purpose flame-retardant adhesive: 1) Synthesize polyether prepolymer; 2) Dry the flame-retardant compound and filler at 125-135°C for 2.8-3.2h, lower to normal temperature, discharge, add polyether prepolymer Polymers and additives, evacuated at 50-60°C for 0.8-1.2h, mixed and stirred for 0.8-1.2h to obtain.

[0025] Among them, the above-mentioned polyether prepolymer is mainly formed by polymerizing polyether polyol and polyester through a catalyst; Arbitrary ratio; the catalyst is pure MDI.

Embodiment 1

[0027] The composition of the multipurpose glue: 46.6 parts of polyether prepolymer (80-90 parts of polyether polyol, 10-20 parts of polyester), 7.3 parts of auxiliary agent, and 46.1 parts of filler.

Embodiment 2

[0029] The composition of the multipurpose glue: 50 parts of polyether prepolymer (80-90 parts of polyether polyol, 10-20 parts of polyester), 3.54 parts of auxiliary agent, and 46.46 parts of filler.

Abstract

The invention discloses a multi-purpose adhesive which mainly consists of a polyether prepolymer, a filling material and aids, wherein the polyether prepolymer is prepared from polyether polyol of which the molecular weight is 50-600, polyether polyol of which the molecular weight is 1000-20000, and polyester through polymerization with a catalyst. The invention further discloses a multi-purpose flame-retardant adhesive which mainly consists of the polyether prepolymer, a flame-retardant composition and aids. The product contains no solvent, is environmental-friendly, is low in toxicity, goodin ultralow temperature resistance, high in adhesion strength, high in oxygen index, good in flame retardancy, free of chemical raw materials which are 'forbidden for use' and ' restricted for use' byinternational chemical associations, and is applicable to adhesion and sealing of various polar and nonpolar substrates.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a multipurpose flame-retardant adhesive and its preparation method and application. Background technique [0002] Flame retardant adhesive is an inorganic polymer adhesive formed by polymerizing inorganic raw materials under high temperature and high pressure. It is mainly used for various structural bonding and sealing in industrial production. At present, most of the flame-retardant adhesives on the market are special-purpose adhesives, that is, a type of flame-retardant adhesive is only suitable for bonding in a specific industrial production field, while there are relatively few types of multi-purpose flame-retardant adhesives, and the existing multi-purpose High-quality flame-retardant adhesives still need to be further improved in terms of bonding strength, oxygen index, applicable temperature range, toxicity, and environmental friendliness.
