Problems solved by technology

[0004] At present, the sound insulation technology in the field of building materials has been disclosed. For example, the Chinese invention patent of CN103571086A discloses a flame-retardant foamed board, which is made of the following raw materials in parts by weight: SG-3PVC resin 100, light calcium carbonate 5- 7. Titanium dioxide 10-14, azodicarbonamide 4-5, hexamethylenetetramine 1.4-1.6, nano-titanium dioxide 2.8-3.2, precipitated barium sulfate 4-6, sodium dodecylbenzenesulfonate 1- 2. Dibutyltin dilaurate 1-2, diethylene glycol dibenzoate 4-5, zinc oxide 2-3, dicumyl peroxide 1-2, modified filler 6-8; The Chinese invention patent of CN108359158A discloses a new type of building sound insulation material and its preparation method, including the following raw materials in parts by weight: polyethylene 30-45 parts, polybutadiene rubber 28-36 parts, kaolin 15-24 parts, asbestos 10-18 parts, 8-17 parts of plant fiber, 12-20 parts of volcanic mud, 8-16 parts of hollow glass microspheres, 7-15 parts of glass fiber, 5-9 parts of montmorillonite, 4-8 parts of nano oxide , 8-13 parts of silica gel particles, 10-16 parts of polyurethane resin particles, 4-9 parts of diatom mud, 8-14 parts of calcium silicate, 4-7 parts of foaming agent, 3-8 parts of antioxidant, flame retardant 4-7 parts and 2-5 parts of plasticizer; although these technical solutions all take into account the light weight insulation, flame retardant and sound insulation effects of the board, the foam molding process will lead to the safety strength and noise insulation effect of the board. There is a large negative impact on

Abstract

The invention discloses an EHS sound insulation board used for building materials. The EHS sound insulation board comprises, by weight, 30-50 parts of natural plant rubber, 2-10 parts of nano-TiO2 ornano-SiO2, 3-6 parts of micrometer wear-resisting particles, 4-7 parts of a foaming agent, 15-35 parts of carbon black or a titanium dioxide filler, 5-10 parts of glass fiber, and 5-8 parts of a plasticizer, wherein the nano-TiO2 or nano-SiO2 uniformly coats the outer surface of natural plant rubber through pre-mixing, and the surfaces of the micrometer wear-resisting particles are coated with a thermoplastic polymer. The invention further relates to the preparation method of the EHS sound insulation board, the EHS sound insulation board has the advantages of being light, high installation strength and excellent sound insulation and flame retardancy and preserving heat, meanwhile the preparation process is simple, and batch production is easy to implement.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an EHS sound insulation board for building materials and a preparation method thereof. Background technique [0002] With the improvement of people's requirements for green and energy-saving living environment, various noises have brought a huge threat to residents living in cities, especially residential residents in complex environments are most affected. How to solve the impact of urban noise and strengthen the anti-noise ability of residential buildings has become an important problem facing the central residential area. [0003] However, the current conventional green ecological residential quarters only focus on greening, waterscape and other hard landscapes as the focus of environmental construction, and pay less attention to the construction of physical environments such as sound, light, and heat in residential quarters, making it difficult to form an overall...
