Problems solved by technology

[0003] The existing PVC board production process includes mixing, banburying, open refining, cutting of fabrics and transparent materials, mold laying, hot pressing, laminating, tempering, curing and static molding, and then according to customer requirements, different moldings can be made. Specifications of products to meet different needs, it can be seen that the production process of the existing PVC board is complicated
[0004] The pressing time of PVC sheet is generally determined according to the experience of the operator. Different plate thicknesses and different operators have different control over the time, resulting in large fluctuations in product quality.

Embodiment 1

[0020] A production method for environmentally friendly PVC wall building materials, comprising the following steps:

[0021] S1: Preparation of PVC base layer: Weigh each component according to the parts by weight, mix each component evenly and put it into the reaction kettle, heat to the material temperature of 135-140°C, stir evenly, and extrude through a twin-screw extruder To the inside of the mold, the working temperature of the twin-screw extruder is 170-180 ℃, and the PVC base material cools down naturally with the plate mold; when the temperature drops to normal temperature, the mold is disassembled and cut to obtain the PVC base layer;

[0022] S2: Preparation of PVC foam layer: weigh each component by weight, weigh each component by weight, mix each component evenly and put it into the reactor, heat until the material temperature reaches 125-130°C, Then quickly transfer the material to the stirring tank for cooling and stirring, and the temperature in the stirring t...

Embodiment 2

[0029] The production method of environmentally friendly PVC wall building materials remains the same as in Example 1, and its working conditions are further limited. The heating temperature of the material in S1 is 138 ° C ± 1 ° C, and the working temperature of the twin-screw extruder is 175 ° C ± 1 ° C. The heating temperature of the material in S2 is 127°C±1°C, the cooling temperature of the stirring tank is 50°C±1°C, the working temperature of the twin-screw extruder is 176°C±1°C, and the roller temperature of the twin-roll plasticizer in S3 At 152℃±1℃;

[0030] At the same time, the materials of the PVC base layer are composed of the following parts by weight: 37 parts of PVC resin, 13 parts of acetyl trioctyl citrate, 7 parts of stearic acid, 10 parts of perlite powder, 13 parts of ethyl acetate, 25 parts of carbon fiber, 1.1 parts of calcium stearate, 5.5 parts of tribasic lead sulfate, 3.2 parts of dioctyl phthalate, 16 parts of corundum powder, 6 parts of titanium di...

Abstract

The invention discloses an environment-friendly PVC wall building material and a production method thereof. The production method comprises the following steps: S1, preparing a PVC base layer; s2, preparing a PVC foaming layer; s3, gluing and pressing the PVC base layer and the PVC foaming layer; and S4, side edge glue sealing. The environment-friendly PVC wall building material is prepared through the method. According to the invention, under the material composition of the base layer and the foaming layer, single-piece production is realized, the preparation difficulty and process requirements are reduced by a thinner layer body structure, and meanwhile, the wall panel body has good performances of corrosion resistance, heat insulation, water resistance, fire resistance and the like; the environment-friendly requirement of the building material market can be met, it can be guaranteed that the material is as stable as an original building material, and the market prospect is huge.

Description

technical field [0001] The invention relates to the technical field of wall building materials, in particular to an environment-friendly PVC wall building material and a production method thereof. Background technique [0002] PVC is a resin resistant to acid, alkali and salt. Because of its good chemical properties and relatively low price, it is widely used in chemical, building materials, light industry, machinery and other industries. PVC rigid board is a widely used product in the industry, especially for thermal insulation materials. [0003] The existing PVC board production processes are mixing, banburying, open-mixing, fabric and transparent material cutting, mold laying, hot pressing, film coating, tempering, curing and static molding, and then according to customer requirements, different shapes can be formed. The products of different specifications can meet different needs. It can be seen that the production process of the existing PVC board is complicated. ...
