[0031] 2. Take acrylate or styrene-acrylic copolymer and mix it with deionized water according to the mass ratio of 1:2 to make styrene-acrylic copolymer emulsion and make component B;

[0032] Step 2: Mix component A and component B with a mass ratio of A:B=100:30 at a temperature of 5 degrees Celsius and mix at a stirring speed of 500 r / min for 10 minutes.

[0033] Among them, the powder preservative is made of 10 parts of methyl carbamate, 2 parts of acetylsalicylic acid, 6 parts...

Embodiment 2

[0040] Step 1, 1. Mix 53 parts of inorganic mineral wool, 10 parts of diatomite particles, 5 parts of hollow glass microspheres, 5 parts of modified silicone rubber powder, 5 parts of nitrile rubber, 1 part of hydroxyethyl cellulose, powder anticorrosion Mix and dry 0.3 parts of agent and 20 parts of heavy calcium carbonate on a heating magnetic stirrer for 1 hour until uniform, and make component A;

[0041] 2. Mix acrylic ester or styrene-acrylic copolymer with deionized water according to the mass ratio of 1:2 to make acrylate emulsion or styrene-acrylic copolymer emulsion to make component B;

[0042] Step 2: Mix component A and component B with a mass ratio of A:B=100:50 at a temperature of 5 degrees Celsius at a stirring speed of 800 r / min for 40 minutes.

[0043] Among them, the powder preservative is made of 10 parts of methyl carbamate, 3 parts of acetylsalicylic acid, 5 parts of propiconazole, and 1 part of zinc cyanurate. Wherein, the inorganic mineral wool is basa...

Embodiment 3

[0048] Step 1, 1. Mix 60 parts of inorganic mineral wool, 7 parts of diatomite particles, 6 parts of hollow glass microspheres, 4 parts of modified silicone rubber powder, 4.5 parts of nitrile rubber, 1 part of hydroxyethyl cellulose, powder anticorrosion Mix and dry 0.3 parts of agent and 12 parts of heavy calcium carbonate on a heating magnetic stirrer for 45 minutes until uniform, and make component A;

[0049] 2. Mix acrylic ester or styrene-acrylic copolymer with deionized water according to the mass ratio of 1:2 to make acrylate emulsion or styrene-acrylic copolymer emulsion to make component B;

Abstract

The invention relates to the technical field of building coatings, and in particular, relates to a two-component floor sound insulation coating and a preparation and production process thereof. The two-component floor sound insulation coating comprises the following two components: a component A of a dry material and a component B of an emulsion type; the mass ratio of the component A to the component B is 100:(5-50). The sound insulation coating has the beneficial effects that: 1, under the mainstream mode and method that slurry or a sound insulation pad is adopted as a sound insulation material at present, the sound insulation material adopting a coating form is provided, the material consumption is reduced, and the cost is reduced; and in terms of operation, one-time spraying forming is achieved, the construction period is short, and complex and diverse procedures do not exist. and 2, an obvious noise reduction effect can be achieved when the coating layer thickness is 1 mm or more. The related requirements of national or local green building acceptance standards for reducing noise by 8-13 db can be met by only using 1.4 kg / m<2> of a material (dry powder), wherein the use amount is different from the use amount of 4 kg / m<2> of most of sound insulation coatings in the current market, so that the material cost is greatly reduced, and the cost performance is high.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a two-component sound-insulating coating for floor slabs and a preparation process thereof. Background technique [0002] With the development of modern industrial technology, housing construction technology has also been improved. Due to the fast construction speed and low production cost, prefabricated buildings have been rapidly promoted all over the world. Prefabricated buildings refer to buildings assembled from prefabricated parts on site. However, the structural strength between the existing prefabricated floor panels and wall panels is not as good as that of cast-in-place columns, beams, floors and roof layers, and cannot meet the requirements for assembling large buildings. [0003] In addition, the requirements for the sound insulation performance of prefabricated buildings are also increasing. At present, the common building sound insulation materials o...
