Problems solved by technology

[0003] Compared with the existing inorganic gypsum, rock wool, perlite and other thermal insulation materials, although the thermal insulation performance is good, the sound insulation performance is relatively insufficient, and the joint part of the filled thermal insulation material and the base material has a different expansion coefficient due to the difference in material. Different, it is easy to separate and fall off in hot and cold environments, and the life of the product is not long
[0004] At present, the on-site foaming materials for walls in the market are mainly made of polyester, which contains toxic gases and is flammable. If a fire occurs, it will cause immeasurable losses to life and property.

Embodiment 1

[0032] The raw material formula is as follows:

[0033]

[0034] At the construction site, mix component A and component B and spray it on the brick wall (the thickness of the brick wall is 20cm, and the thickness of the coating is 3cm). The weighted sound insulation of the obtained wall is 42dB.

Embodiment 2

[0036] The raw material formula is as follows:

[0037]

[0038] At the construction site, mix component A and component B and spray it on the brick wall (the thickness of the brick wall is 20cm, and the thickness of the coating is 3cm). The weighted sound insulation of the obtained wall is 50dB.

Embodiment 3

[0040] The raw material formula is as follows:

[0041]

[0042] At the construction site, mix component A and component B and spray it on the brick wall (the thickness of the brick wall is 20cm, and the thickness of the coating is 3cm). The weighted sound insulation of the obtained wall is 48dB.

Abstract

The invention provides on-site foaming adhesive for a wall. The on-site foaming adhesive comprises a component A and a component B, wherein the component A comprises, by weight, 50 parts of melamino-formaldehyde serving as the main raw material, 40-60 parts of polyether polyol, 30-40 parts of crosslinking agent, 4-8 parts of stabilizer, 0-2 parts of catalyst, 20-40 parts of foaming agent, 0-2 parts of solvent and 10-20 parts of flame retardant; the component B is 200-300 parts of isocyanate. The on-site foaming adhesive using the melamine as the main raw material is incombustible, free of toxic substances and gas and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of organic compound compositions, in particular to an organic composition containing polysiloxane and its application. Background technique [0002] The thermal insulation wall is composed of adhesive layer, base material, anchor piece, sealing material, etc., and has the functions of thermal insulation and sound insulation. The existing sound insulation and thermal insulation wall composition includes: light steel keel paper-faced gypsum board wall, Light steel keel fiber cement board wall or double-layer 3mm thick steel plate, filled with 80mm rock wool in the middle. [0003] Compared with the existing inorganic gypsum, rock wool, perlite and other thermal insulation materials, although the thermal insulation performance is good, the sound insulation performance is relatively insufficient, and the joint part of the filled thermal insulation material and the base material has a different expansion coefficient due to...
