Problems solved by technology

[0002] In recent years, with the continuous improvement of sound insulation requirements for floors and floors in construction projects, finished sound insulation mats made of various rubber or polyethylene materials have been more and more widely used and promoted in various projects, and have been widely developed. After the pad is formed in the factory, it is transported to the construction site. Workers use adhesive mortar to firmly bond the sound insulation pad to the ground base. The cost is high and the construction is cumbersome. More importantly, after the laying of this type of sound insulation pad, the surface is smooth. The cushion material on it is not easy to form a whole, usually called two-layer skin, which is easy to cause the hollowing and cracking of the entire cushion

Embodiment 1

[0014] Example 1: A soundproof pad made of rubber particles is prepared by mixing the following raw materials in parts by weight: 70 parts of cement, 500 parts of waste rubber powder, 40 parts of rubber powder, 1 part of MC, and 2 parts of fiber.

[0015] The cement is Portland cement above grade 32.5, ordinary Portland cement, slag Portland cement, fly ash cement, sulphoaluminate cement or iron-aluminate cement; the waste rubber powder is 20-120 mesh modified rubber powder or ordinary rubber powder; the rubber powder is polymer rubber powder; the MC is methyl hydroxyethyl cellulose ether and methyl hydroxypropyl cellulose ether. The fibers are: alkali-resistant glass fibers, vinylon fibers, polypropylene fibers, and acrylic fibers with a length of 5 mm to 15 mm. The filler is polystyrene particles or waste polyurethane particles.

[0016] Firstly, the above-mentioned raw materials are dried.

Abstract

A rubber particle soundproof pad is prepared by mixing the following raw materials in parts by weight: 50-150 parts of cement, 500-1000 parts of waste rubber powder, 20-50 parts of rubber powder, 1-5 parts of MC, and 1-5 parts of fiber. The invention has the following advantages: excellent sound insulation performance, convenient and quick construction, and effective mitigation of hollowing and cracking of floor cushions. Due to the good flexibility and elasticity of the waste rubber powder, it has an excellent reduction effect on the noise generated by the impact on the floor. The invention can be carried out on the construction site. After the mixed finished product is evenly mixed with water, the working surface can be pumped by mechanization, and the mechanical spray gun can be used to spray evenly on the floor of the building. The construction is convenient and fast, and the labor intensity is reduced. After the construction of the present invention is completed, when the composite light aggregate or foamed concrete is constructed on it, the bonding performance with the cushion material can be increased, thereby reducing or alleviating the hollowing and cracking of the cushion and the sound insulation layer.
