Problems solved by technology

[0005] Then the existing glass wool also has certain disadvantages, that is, it is relatively loose and soft and cannot be effectively formed, and it cannot have a fixed shape, which limits its scope of use. In addition, the existing glass wool has all used phenolic resin containing formaldehyde as Glass wool binder releases free formaldehyde during the production and use of glass wool, causing certain harm to the human body, further restricting the development and expansion of the application field of glass wool products

Embodiment 1

[0018] Adhesive formula: 50 parts of tetraethylene glycol dimethacrylate, 20 parts of epoxy acrylate diester, 2 parts of cumene peroxide, 1 part of acrylic acid, 1 part of triethylamine, 0.1 part of saccharin, hydrogen 0.5 parts of quinone, 10 parts of acrylic resin powder, 0.5 parts of bentonite, and 100 parts of water.

[0019] Mix 50 parts of tetraethylene glycol dimethacrylate, 20 parts of epoxy acrylate diester, 2 parts of cumene peroxide and an appropriate amount of water, then add 1 part of acrylic acid, 1 part of triethylamine, and 0.1 parts of saccharin After the reaction, 10 parts of acrylic resin powder, 0.5 parts of bentonite and an appropriate amount of water were added and mixed to obtain an adhesive.

[0020] Spray the obtained adhesive evenly on the glass wool with an average fiber diameter of 2-5 μm, take a thickness of 20mm, and place two pieces of high-silica glass fiber mesh cloth on the glass wool that has been sprayed with the adhesive. The side and the ...

Embodiment 2

[0022] Adhesive formula: 60 parts of tetraethylene glycol dimethacrylate, 35 parts of epoxy acrylate diester, 4 parts of cumene peroxide, 2 parts of acrylic acid, 2 parts of triethylamine, 0.5 parts of saccharin, hydrogen 1 part of quinone, 15 parts of acrylic resin powder, 3 parts of silicon micropowder, 110 parts of water. The preparation method of the adhesive is the same as in Example 1.

[0023] Spray the obtained adhesive evenly on the glass wool with an average fiber diameter of 2-5 μm, take a thickness of 20mm, and place two pieces of high-silica glass fiber mesh cloth on the glass wool that has been sprayed with the adhesive. The side and the lower side are tightly pressed, and at room temperature, after the glue dries, a new type of sound-absorbing and heat-retaining glass wool product is obtained.

Embodiment 3

[0025] Adhesive formula: 50 parts of tetraethylene glycol dimethacrylate, 20 parts of epoxy acrylate diester, 2 parts of cumene peroxide, 1 part of acrylic acid, 1 part of triethylamine, 0.1 part of saccharin, hydrogen 0.5 parts of quinone, 10 parts of acrylic resin powder, 0.5 parts of titanium dioxide, and 100 parts of water. The preparation method of the adhesive is the same as in Example 1.

[0026] Spray the obtained adhesive evenly on the glass wool with an average fiber diameter of 2-5 μm, take a thickness of 20mm, and place two pieces of high-silica glass fiber mesh cloth on the glass wool that has been sprayed with the adhesive. The side and the lower side are tightly pressed, and at room temperature, after the glue dries, a new type of sound-absorbing and heat-retaining glass wool product is obtained.

Abstract

The invention discloses an A-level flame-retardant sound-absorbing and heat-insulating laminated glass wool product, which comprises a mesh fabric, glass wool and an adhesive, and is of a sandwich structure, wherein the mesh fabric is arranged at an outer layer; flocculated glass wool uniformly sprayed with an adhesive is arranged on an intermediate layer; the mesh fabric is glass fiber which is woven by a middle-alkali or alkali-free glass fiber yarn and coated with an alkali-resistant polymer emulsion; the glass wool is an elastic felty body prepared from flocculated fine glass fibers; and the mean fiber diameter is 2-5 microns. The sound-absorbing and heat-insulating laminated glass wool product is excellent in thermal insulation effect and good in elastic resilience and has a good sound-absorbing effect. Due to use of the glass fiber mesh fabric, the product has good corrosion resistance on chemical substances, such as acid and alkali and high warp and weft tensile strength, and the defect of single glass wool is compensated.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a grade-A flame-retardant sound-absorbing heat-preservation veneer glass wool product. Background technique [0002] Glass wool is a product made by fibrating molten glass and adding an environmentally friendly formula binder based on thermosetting resin. It is an elastic felt made of glass fibers with a diameter of only a few microns. And according to the requirements of use, different moisture-proof veneers can be selected for online compounding. It has a large number of tiny air pores, which make it play the role of thermal insulation, sound absorption and noise reduction, and safety protection. It is the best material for thermal insulation, sound absorption and noise reduction of steel structure buildings. [0003] Glass wool is based on fixed-length glass fibers with irregular arrangement, some changes in diameter but fairly uniform diameter distribution, attached with...
