Description
Technical Field
The invention belongs to the technical field of adhesive materials, and particularly relates to flame-retardant high-temperature-resistant environment-friendly glue and a preparation method thereof.
Background
The environment-friendly glue is also called foaming type single-component polyurethane adhesive, and is a moisture-cured polyurethane adhesive. The adhesive has the advantages of high initial adhesion, room temperature curing, foaming of the cured adhesive layer, moderate foaming height, high bonding strength, convenient construction and the like. Therefore, the adhesive is widely applied to the adhesion of steel plates, wood blocks, steel plates, honeycomb papers and the like of the inner layers of the burglary-resisting doors. The synthesis and solidification principle of the environment-friendly glue are as follows: the foaming type single-component polyurethane adhesive mainly comprises the steps of reacting hydroxyl with isocyanate groups in the synthesis stage to generate a prepolymer; the curing stage is mainly that water reacts with isocyanate to generate amino compounds, and the amino compounds react with isocyanate to generate urea compounds. The composition of the adhesive layer after the single-component polyurethane adhesive is cured is a polyurethane-polyurea structure. The solidified adhesive layer has stable physical and chemical properties, is insoluble in solvents, does not melt at the temperature of below 200 ℃, has the advantages of water resistance, rust resistance and the like, and can be widely used in a plurality of fields.
The foaming adhesive of the Minui brand of the company is mainly applied to the adhesion of filling materials in cavities of steel doors, burglarproof doors, fireproof doors, wooden doors, furniture and the like, and has the characteristics of quick solidification at normal temperature, toughness of an adhesive layer after solidification, strong adhesion force of the adhesive after high temperature and the like. Can be widely applied to the bonding of steel plates with paper cores, wood boards, perlite, magnesium oxide and inorganic boards.
Sorting foaming glue:
1. fireproof plate glue
The method is suitable for fireproof doors. And the perlite is adhered to the fireproof plate and is high-temperature resistant. Shelf life 3 (month)
2. Stainless steel door foam glue
Is suitable for stainless steel doors. Adhesion of foam board to stainless steel board. Shelf life 3 (month)
3. Honeycomb paper foaming glue
Is suitable for steel wood doors. The adhesion between the steel plate and the honeycomb paper is high temperature resistant. Shelf life 3 (month)
For example, a common non-environmental glue formulation is as follows:
(1) The isocyanate, polyester polyol, polyether polyol, solvent and catalyst were added in a certain ratio to 200 kg in total into a large iron drum (250 kg standard drum), and then added to a rocking machine and rocked for 90 minutes. After that, 2 kg of the sample was sampled, and the relevant viscosity value was detected, and the tensile value after bonding and curing was measured. And (5) after the product is qualified. And the product can be delivered.
(2) The isocyanate, polyester polyol, polyether polyol, solvent and catalyst were added in a certain ratio to 200 kg in total into a large iron drum (250 kg standard drum), and then added to a rocking machine and rocked for 90 minutes. After that, 2 kg of the sample was sampled, and the relevant viscosity value was detected, and the tensile value after bonding and curing was measured. And (5) after the product is qualified. And the product can be delivered. The glues herein have a viscosity number of 80-100 (mpa.s 25 ℃) to bond the honeycomb paper, a viscosity number of 800-1000 (mpa.s 25 ℃) to bond the fire-protection plate, and a viscosity number of 2000-3000 (mpa.s 25 ℃) to bond the foam.
(3) The isocyanate, polyester polyol, polyether polyol, solvent and catalyst were added in a certain ratio to 200 kg in total into a large iron drum (250 kg standard drum), and then added to a rocking machine and rocked for 90 minutes. After that, 2 kg of the sample was sampled, and the relevant viscosity value was detected, and the tensile value after bonding and curing was measured. And (5) after the product is qualified. And the product can be delivered. The glues herein have a viscosity number of 80-300 (mpa.s 25 ℃) to bond the honeycomb paper, a viscosity number of 800-1500 (mpa.s 25 ℃) to bond the fire-protection plate, and a viscosity number of 2000-4000 (mpa.s 25 ℃) to bond the foam.
At present, most of the existing glues have the problem of non-environmental protection, and meanwhile, in order to improve the flame retardance and high temperature resistance, a large amount of high temperature resistant powder is added, so that the viscosity and the bonding strength of the glues are seriously influenced, and the problem of subsequent pollution is also brought.
