Embodiment 1

[0023] In this embodiment, a method for preparing an environmentally friendly sound-insulating wood-plastic wall material comprises the following steps:

[0024] a. Add lignocellulosic material, montmorillonite, wood scraps, rhodoxene, fluoroapatite, hempcell fiber, antimony trioxide, silicone powder, silkworm excrement, carbonized graphite and vermiculite powder to high-speed mixing machine, then add the coupling agent solution dropwise while stirring, then raise the temperature to 80°C and stir for 30 minutes to obtain the mixture M, which is set aside;

[0025] b. Transfer the mixture M to a cold mixer for cooling. After the mixture M is cooled to 40°C, add dibutyl sebacate, dibutoxyethyl azelate, butyl acrylate, diisohydroperoxide Propylbenzene, dioctyl phthalate and maleic anhydride grafted polyethylene are stirred evenly to obtain mixture N, which is for subsequent use;

[0026] c. Put the compound N into the twin-screw extruder, wherein the head temperature of the twin...

Embodiment 2

[0033] In this embodiment, a method for preparing an environmentally friendly sound-insulating wood-plastic wall material comprises the following steps:

[0034] a. Add lignocellulosic material, montmorillonite, wood scraps, rhodoxene, fluoroapatite, hempcell fiber, antimony trioxide, silicone powder, silkworm excrement, carbonized graphite and vermiculite powder to high-speed mixing machine, then add the coupling agent solution dropwise while stirring, then raise the temperature to 95°C and stir for 80 minutes to obtain the mixture M, which is set aside;

[0035] b. Transfer the mixture M to a cold mixer for cooling. After the mixture M is cooled to 60°C, add dibutyl sebacate, dibutoxyethyl azelate, butyl acrylate, diisohydroperoxide Propylbenzene, dioctyl phthalate and maleic anhydride grafted polyethylene are stirred evenly to obtain mixture N, which is for subsequent use;

[0036] c. Put the compound N into the twin-screw extruder, wherein the head temperature of the twin...

Embodiment 3

[0043] In this embodiment, a method for preparing an environmentally friendly sound-insulating wood-plastic wall material comprises the following steps:

[0044] a. Add lignocellulosic material, montmorillonite, wood scraps, rhodoxene, fluoroapatite, hempcell fiber, antimony trioxide, silicone powder, silkworm excrement, carbonized graphite and vermiculite powder to high-speed mixing machine, then add the coupling agent solution dropwise while stirring, then raise the temperature to 88°C and stir for 65 minutes to obtain the mixture M, which is set aside;

[0045] b. Transfer the mixture M to a cold mixer for cooling. After the mixture M is cooled to 50°C, add dibutyl sebacate, dibutoxyethyl azelate, butyl acrylate, diisohydroperoxide Propylbenzene, dioctyl phthalate and maleic anhydride grafted polyethylene are stirred evenly to obtain mixture N, which is for subsequent use;

[0046] c. Put the compound N into the twin-screw extruder, wherein the head temperature of the twin...

Abstract

The invention discloses a preparation method of an environment-friendly and sound-insulating wood-plastic wall material. The preparation method comprises steps as follows: a, wood fiber materials, montmorillonite, wood leftover materials, manganolite, fluorapatite, Jutecell fibers, antimony trioxide, silicone powder, silkworm excrement, carbonized graphite and vermiculite powder are added to a high-speed mixer, a coupling agent solution is dropwise added, the mixture is heated and stirred, and a mixture M is obtained; b, after the mixture M is cooled, sebacic acid dibutyl ester, azelaic acid dibutoxy ethyl ester, butyl acrylate, diisopropylbenzene hydroperoxide, dioctyl phthalate and maleic anhydride grafted polyethylene are added, the mixture is stirred uniformly, and a mixture N is obtained; c, the mixture N is extruded and granulated, and master batch is obtained; d, the master batch obtained in the step c is processed and formed, and the wood-plastic wall material is obtained. According to the prepared wood-plastic wall material, the problems that a conventional sound-insulating wall material is prone to ageing and has poor thermal insulation and sound insulation effects are solved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method of an environment-friendly sound-insulating wood-plastic wall material. Background technique [0002] With the rapid development of the construction industry, the issue of energy conservation and environmental protection has attracted more and more attention. Noise has become one of the main environmental pollution. Various noises are produced in the surrounding environment of our life, such as the noise produced by cars or buildings, and other noisy sounds. These noises will greatly affect people's quality of life . At present, the commonly used noise reduction method is to use sound insulation materials, such as sound insulation door panel materials, sound insulation wall materials, and sound insulation sealing strips. Traditional sound insulation wall materials mainly include foam products such as glass wool, rock wool and polystyrene. However...
