Problems solved by technology

The adhesives currently used are all water-based adhesives, and the following problems occur during use: 1. The bonding strength is low. During spraying construction or when the sprayed layer is in a wet state, local peeling and adhesive flow are prone to occur Especially when the ambient temperature is low, the peeling of the sprayed layer and the flow of the adhesive are more serious
2. The binder has...

Embodiment 1

[0028] Embodiment 1: The thickness of the thermal insulation fiber sprayed layer is 5mm-30mm, the construction environment temperature is above 5°C, and 100kg of adhesive is produced.

[0029] Add 79.6kg of pure water, 8.5kg of pure acrylate copolymer emulsion sieved through a 40-mesh stainless steel wire filter, and 1.75kg of acrylic acid associative thickener into the plastic container in turn. After stirring with an electric mixer for 1-2 minutes, add 10kg of water-soluble ammonium polyphosphate flame retardant sieved through a 40-mesh stainless steel wire filter and di, methyl-di, amino-one, propanol multifunctional additives 0.05kg and isothiazolone antifungal agent 0.1kg, and finally use an electric stirrer at 500-550 rpm to stir the mixture for 5-8 minutes.

Embodiment 2

[0030] Embodiment 2: The thickness of the thermal insulation fiber sprayed layer is 40mm-50mm, the construction environment temperature is between 0°C-5°C, and 100kg of adhesive is produced.

[0031] Add 69.71kg of pure water, 12.5kg of pure acrylate copolymer emulsion sieved through a 40-mesh stainless steel wire filter, and 2.57kg of acrylic acid associative thickener in the plastic container, and the mixture is heated by an electric motor at 500-550 rpm. After stirring with the agitator for 1-2 minutes, first add 0.5 kg of alcohol ester-12 film-forming aid, and then sequentially add 14.5 kg of water-soluble ammonium polyphosphate flame retardant sieved through a 40 mesh stainless steel wire filter and di, methyl -2, amino-1, 0.07kg of propanol multifunctional additive and 0.15kg of isothiazolone antifungal agent, and finally use an electric stirrer at 500-550 rpm to stir the mixture for 5-8 minutes to obtain the product.

Abstract

The invention discloses a method for preparing an appropriative bonding agent for fiber spraying, which is insulating, absorb in sound adiabatic. It consists of pure acrylic ester emulsion, acrylic acid associative thickeners, water soluble trochaic ammine, burning retardant, dim ethyl, diamino,1-propanol, multifunction substance and purified water. After mixing them and stirring, comes the bonding agent. It has many advantages: high binding strength, high resistively against water and hydrophobic after dryness or film formation, high flame retardancy, atoxigenic and flavorless and resistant to corrosion, etc. Besides, it is low-cost, high-performance, and easy to generalize.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a special adhesive for thermal insulation, sound absorption and thermal insulation fiber spraying and a preparation method thereof. 2. Background technology [0002] Binder is the main raw material used in thermal insulation fiber spraying construction. It is sprayed by the nozzle of the fiber spraying machine and mixed evenly with the heat-insulating fiber in an instant, and the heat-insulating fiber is bonded to the surface of the object to be sprayed in a three-dimensional state to form a sprayed layer, which plays a role in thermal insulation, sound absorption and sound insulation for the object to be sprayed. role. The adhesives currently used are all water-based adhesives, and the following problems occur during use: 1. The bonding strength is low. During spraying construction or when the sprayed layer is in a wet state, local peeling and adhesive ...
