Embodiment 1

[0027] The present invention utilizes waste and old polyvinyl chloride to produce the method for fireproof light-weight thermal insulation wall board, and it comprises the following steps:

[0028] A. Prepare raw materials waste polyvinyl chloride, fly ash, 1801 stearic acid, dioctyl phthalate and magnesium hydroxide;

[0029] B. Sorting the waste PVC raw materials, sorting out waste paper, cards, glass containers and other visible sundries, after sorting, use a crusher or shearing machine or shred the waste PVC raw materials After coarse crushing, the waste PVC raw materials are screened and iron-removed magnetically separated. After screening and iron-removed magnetic separation, the waste PVC raw materials are cleaned to remove waste PVC raw materials. All kinds of oil, dust and sand are stained on it;

[0030] C. Send the cleaned waste polyvinyl chloride raw materials into the cyclone separator for mechanical centrifugal dehydration and drying, then let the waste polyviny...

Abstract

The invention provides a method for producing a fireproof lightweight heat preservation wall panel by using waste polyvinyl chloride. The method comprises the following steps: preparing raw materials, adding 210-230 parts by weight of pulverized fuel ash, 0.9-1.1 part by weight of 1801 type stearic acid, 2-4 parts by weight of dioctyl phthalate and 7-9 parts by weight of magnesium hydroxide based on 100 parts by weight of waste polyvinyl chloride raw material to a high-speed mixer, mixing and stirring mixed materials, heating to 110 DEG C-140 DEG C, then adding the mixed materials to a screw extruder, and maintaining the temperature of the screw extruder at 170 DEG C to 190 DEG C. The invention aims at providing the method for producing the fireproof lightweight heat preservation wall panel with high strength and good heat preservation and heat insulation properties by using waste polyvinyl chloride and the fireproof lightweight heat preservation wall panel product. According to the method provided by the invention, lots of waste polyvinyl chloride can be used as the raw material for producing the panel, so that waste polyvinyl chloride can be prevented from polluting the environments.

Description

technical field [0001] The invention relates to a method and a product for producing a fireproof light-weight thermal insulation wallboard by using waste polyvinyl chloride. Background technique [0002] Existing fire-proof lightweight thermal insulation wall panels generally have low strength, poor thermal insulation and thermal insulation performance, and it is difficult to meet the higher strength and energy-saving requirements of buildings. Due to low strength, poor thermal insulation and thermal insulation performance, It has to thicken the wall material to ensure the strength and energy-saving requirements. After use, it will occupy a large building area and waste the effective use of space. In addition, a large amount of waste polyvinyl chloride produced in life and production is difficult to deal with, resulting in serious pollution to the environment. Contents of the invention [0003] The purpose of the present invention is to provide a board body that can use a...
