Problems solved by technology

The main disadvantage of these materials is that they are flammable (although some are flammable, but they also have a large amount of smoke), the gas is poisonous, and it is extremely harmful to the human body.
And the raw materials are mainly high-carbon, non-renewable and recycled materials

preparation example Construction

[0018] The preparation of the waste spun felt is a felt material made by non-woven processes such as opening the fiber mixture raw material, carding, air-laid, needle-punched and felted.

[0019] The steps of the modified agent vacuum infiltration process are as follows: the billet is processed by an extrusion impregnation equipment equipped with a liquid modifier; the billet is first sent to a pair of extrusion rollers for rolling, The air in the gap is extruded and enters the dipping tank at the same time, so that the liquid modifier penetrates into the billet under the action of the external ambient air pressure; and then passes through a pair of adjusting extrusion rollers to make the modifier content of the billet meet the specified requirements; The vacuum infiltration treatment conditions of the billet are changed according to the concentration, viscosity and infiltration amount of the modified liquid. Generally, the extrusion roller pressure is 0.1-1.0MPa; the extrusion...

Embodiment 1

[0026] Waste textiles containing cotton fibers, hemp fibers, and various synthetic fibers obtained by crushing, defibrating, and opening the various waste textiles collected, such as various waste clothes, towels, bed sheets, and other waste household textiles. mixture.

[0027] The felt made of the fiber mixture raw material obtained in the previous step through opening, carding, air-laid, needle-punched and other non-woven processes. Cut the felt into blanks with certain specifications.

[0028] The billet is injected with a modifier through a vacuum infiltration process. The process is as follows: first, the billet is sent to a pair of extrusion rollers for rolling, and then enters the impregnation tank while squeezing out the air in the gap, so that the liquid modifier It penetrates into the billet under the action of external ambient air pressure. The billet extrusion roller pressure is 0.5 MPa; the extrusion speed is 0.5 m / s, and the processing temperature is room temp...

Embodiment 2

[0031] The waste spinning mat is cut into a billet with a certain specification and squeezed through the squeeze roller, and the air is removed and then enters the dipping tank. The liquid modifier in the tank penetrates into the billet under the action of the external ambient air pressure. The billet extrusion roller pressure is 0.6 MPa; the extrusion speed is 0.2 m / s, and the processing temperature is room temperature. The infiltrated billet is then extruded by a pair of regulating extrusion rollers to make the modifier content of the billet reach the requirement of 10% of the total weight of the material. The liquid modifier in the tank is a mixed solution of 25% aqueous isocyanate emulsion plus 5% boric acid-borax aqueous solution.

[0032] The blanks treated above are superimposed and placed on a rigid flat plate, and the blanks are separated by thin metal plates. Then add a flat weight on the top of the billet (stack), and apply a pressure of 1 MPa on the weight, while...

Abstract

The invention discloses a method for manufacturing light-weight building boards by using recovered textile fibers, which comprises the following steps: using the mixture of cotton fibers and various synthetic fibers obtained through the process of crushing and opening waste textiles as raw materials, and then passing The raw material of waste spinning felt is made by non-woven process; the raw material of waste spinning felt is cut into blanks of certain specifications, and then the blanks are made into lightweight and high-strength building boards through vacuum infiltration and high temperature fixing process with modifiers . To sum up, the present invention collects and processes various waste daily-use textiles to make light-weight and high-strength building boards, which not only solves the problem of waste textile disposal, but also reduces construction costs and energy consumption.

Description

technical field [0001] The invention relates to a manufacturing process of lightweight building boards, in particular to a method for manufacturing lightweight building boards by utilizing recycled textile fibers. Background technique [0002] Textiles are one of the most used textile materials in the world, and they are also indispensable daily necessities for people. However, there is also a huge amount of discarded textile materials every year, and how to reuse these discarded textile materials has become one of the problems that must be solved. [0003] In modern buildings, the modularization and lightweight of building construction is one of the important ways to increase construction speed and reduce construction cost and energy consumption. In modern buildings, the currently popular fast-installed building wall panels are mainly composed of steel plate sandwich foamed plastic materials. The main disadvantage of these materials is that they are flammable (although ...
