Embodiment Construction

[0019] Take each component by weight ratio in Table 1

[0020] The weight proportion of table 1 embodiment 1~embodiment 3

[0021]

[0022]

[0023] The above-mentioned waste rubber powder particle diameter is 2~3mm.

[0024] The above-mentioned waste rubber powder is made of styrene-butadiene rubber.

[0025] The foaming agent is azodicarbonamide.

[0026] The plant fiber is a mixture of corn stalks, hemp fibers, paper chips or wood chips in any proportion.

[0027] The diameter of the plant fiber is 0.5-3mm, and the length is 1-10mm. Its preparation method is:

[0028] S1: Mix anhydrous magnesium chloride, magnesium sulfate, glass fiber, potassium titanate whiskers and half of the water, and stir evenly;

[0029] S2: Add waste rubber powder, kaolin, coal ash, closed-cell perlite, talcum powder, titanium dioxide, white carbon black, alumina, graphite, polyethylene, plant fiber, ceramic fiber, pumice powder, paraffin, to the mixture obtained in S1. Zinc oxide, mull...

Abstract

The invention provides a filling material for a sandwiched building plate, which belongs to the technical field of building materials. The filling material is prepared from the following raw materials by weight: 1 to 2 parts of anhydrous magnesium chloride, 1 to 2 parts of magnesium sulfate, 1 part of glass fiber, 1 part of potassium titanate whisker, 5 to 8 parts of waste rubber powder, 3 to 6 parts of kaolin, 3 to 6 parts of coal ash, 2 to 4 parts of closed-cell perlite, 5 to 8 parts of talcum powder, 1 to 2 parts of titanium dioxide, 3 to 5 parts of white carbon black, 3 to 7 parts of alumina, 1 to 3 parts of graphite, 5 to 8 parts of polyethylene, 14 to 20 parts of vegetable fiber, 2 to 4 parts of ceramic fiber, 3 to 6 parts of pumice sand, 1 to 2 parts of paraffin, 1 to 2 parts of zinc oxide, 5 to 9 parts of mullite, 1 to 2 parts of carbon fiber, 5 to 8 parts of diatomite, 3 to 6 parts of a foaming agent and 30 to 50 parts of water. The filling material for a sandwiched building plate provided by the invention has sound insulation and thermal insulation effects and is applicable to building plates.

Description

technical field [0001] The invention provides a filling material for a sandwich room board, which belongs to the technical field of building materials. Background technique [0002] Prefabricated houses are becoming more and more common in people's daily life. Because they can be disassembled and assembled, they are widely used in post-disaster reconstruction, temporary housing and field operations. [0003] The prefabricated house is usually composed of a house board, the outside of the house board is a board made of metal or engineering plastic, and there is a filling material in the middle. Filling materials need to have good thermal insulation and fire performance, and also need to have suitable strength. The deficiencies of the filling materials of the existing board houses include the disadvantages of poor thermal insulation performance and sound insulation performance, which will affect the comfort of living. [0004] In addition, due to the rapid economic developme...
