Problems solved by technology

In the prior art, the wall construction materials are mainly clay solid bricks and cement hollow blocks, which are bulky and heavy, have poor thermal insulation, heat insulation, and sound insulation effects, and are inconvenient for construction. Cracks often appear on the surface and affect the quality and performance of the building
In addition, the raw material clay and cement of this wall material are non-renewable resources, and a large amount of clay and cement does not meet the requirements of the era of energy saving and environmental protection

Embodiment 1

[0021] A method for making a wallboard, comprising the steps of:

[0022] (1), preparation of mixed pulp: get 15 parts of industrial waste wood pulp (provided by Suzhou Hongye Paper Mill); 20 parts of waste straw (purchased by peasant households in northern Jiangsu); 38 parts of textile chemical fiber flying flowers (provided by Huangdai Chemical Fiber Textile Factory, Xiangcheng District, Suzhou); 12 parts of dry lime are crushed into slurry respectively, and stirred and mixed to obtain mixed slurry;

[0023] (2), above-mentioned mixed slurry is carried out static sedimentation, takes out sediment after draining the water above;

[0024] (3) After the sediment is spread on the spreader, it is sent into the press, and it is hot-pressed into a trapezoidal wave shape at a temperature of about 280 ° C and a pressure of 12 kg. The pressing time depends on the product requirements of different thicknesses, about 4 to 8 minutes or so.

Embodiment 2

[0026] A method for making a wallboard, comprising the steps of:

[0027] (1), preparation of mixed pulp: get 20 parts of industrial waste wood pulp (provided by Suzhou Hongye Paper Mill); 20 parts of waste straw (purchased by peasant families in northern Jiangsu); 33 parts of textile chemical fiber flying flowers (provided by Huangdai Chemical Fiber Textile Factory, Xiangcheng District, Suzhou); 17 parts of dry lime are crushed into slurry respectively, and stirred and mixed to obtain mixed slurry;

[0028] (2), above-mentioned mixed slurry is carried out static sedimentation, takes out sediment after draining the water above;

[0029] (3) After the sediment is spread on the spreader, it is sent into the press, and it is hot-pressed into a trapezoidal wave shape at a temperature of about 280°C and a pressure of 12 kg. The pressing time depends on the product requirements of different thicknesses, about 4 to 8 minutes or so.

Embodiment 3

[0031] A method for making a wallboard, comprising the steps of:

[0032] (1), preparation of mixed pulp: get 10 parts of industrial waste wood pulp (provided by Suzhou Hongye Paper Mill); 20 parts of waste straw (purchased by peasant families in northern Jiangsu); 30 parts of textile chemical fiber flying flowers (provided by Huangdai Chemical Fiber Textile Factory, Xiangcheng District, Suzhou); 12 parts of dry lime are crushed into slurry respectively, and stirred and mixed to obtain mixed slurry;

[0033] (2), above-mentioned mixed slurry is carried out static sedimentation, takes out sediment after draining the water above;

[0034] (3) After the sediment is spread on the spreader, it is sent into the press, and it is hot-pressed into a trapezoidal wave shape at a temperature of about 250 ° C and a pressure of 13 kg. The pressing time depends on the product requirements of different thicknesses, about 3 to 6 minutes or so.

Abstract

The invention relates to a method for manufacturing a high-density light-weighted wall panel; the density of the high-density light-weighted wall panel is more than 0.09g / cm3, and the raw material formula of the wall panel in parts by weight is as follows: 15 to 20 parts of industrial waste wood pulp, 19 to 25 parts of waste straw, 10 to 20 parts of inorganic fiber in domestic garbage, 30 to 40 parts of textile and chemical fiber fly, 5 to 17 parts of dry lime; and the manufacturing method comprises the following steps: mixing, precipitation and hot pressing at 250 to 320DEG C and 10 to 50kg of pressure. The method takes industrial, agricultural and domestic waste as the raw materials to manufacture the wall panel, utilizes the waste, reduces the waste treatment cost and the wall panel production cost, achieves the dual purposes of economy and environmental protection, and simultaneously has simple process and is convenient to operate; and the manufactured wall panel is a high-densitylight-weighted inorganic fiberboard, can be used for manufacturing hollow membrane plates of hollow wall bodies, and has excellent heat insulating, sound-absorbing and anti-seismic performance.

Description

technical field [0001] The invention relates to a method for making high-density light-weight wallboards, in particular to a method for making wallboards from industrial waste wood pulp, agricultural straw and domestic garbage. Background technique [0002] At present, our country is in the "double peak" period of urban housing construction and new rural construction, and it is also a critical period for our country's energy conservation, emission reduction and human environmental protection. The new energy and environment-friendly materials for wall panels and their production technologies have broad social and market demands and development prospects. In the prior art, the wall construction materials are mainly clay solid bricks and cement hollow blocks, which are bulky and heavy, have poor thermal insulation, heat insulation, and sound insulation effects, and are inconvenient for construction. Cracks often appear on the surface and affect the quality and performance of t...
