Embodiment 1

[0042] The specific steps of a production process of an anti-wicking architectural membrane are as follows:

[0043] (1) Preparation of base cloth

[0044] The polyester yarn is woven into a base cloth by a double warp and double weft weaving method; the base cloth is twisted in the weft direction during the preparation process. The structural parameters of the base fabric are: yarn thickness: 1000D in the warp direction, 1000D in the weft direction; fabric density: 30 threads / inch in the warp direction, and 30 threads / inch in the weft direction. The grammage of the base cloth is 263 grams per square meter.

[0045] (2) Preparation of pvc slurry

[0046] The formula of the pvc slurry is as follows (parts by weight): 95 parts of pvc paste resin, 60 parts of epoxy soybean oil, 2.5 parts of barium zinc stabilizer, 7 parts of flame retardant, 0.3 part of anti-ultraviolet agent, 9 parts of nanometer calcium, 0.3 part of mildew-proof and antibacterial agent.

Embodiment 3

[0068] The specific steps of a production process of an anti-wicking architectural membrane are as follows:

[0069] (1) Preparation of base cloth

[0070] The polyester yarn is woven into a base cloth by a double warp and double weft weaving method; the base cloth is twisted in the weft direction during the preparation process. The structural parameters of the base fabric are: yarn thickness: 1500D in the warp direction, 1500D in the weft direction; fabric density: 30 threads / inch in the warp direction, and 34 threads / inch in the weft direction. The grammage of the base cloth is 421 grams per square meter.

[0071] (2) Preparation of pvc slurry

[0072] The formula of described pvc slurry is as follows (parts by weight): 100 parts of pvc paste resin, 62.5 parts of epoxy soybean oil, 2.75 parts of barium zinc stabilizer, 8 parts of fire retardant, 0.4 part of anti-ultraviolet agent, 10 parts of nanometer calcium, 0.4 parts of anti-mold and antibacterial agent.

Abstract

The embodiment of the invention discloses a production technology of an anti-wicking building membrane, and relates to the technical field of building materials. The production technology comprises the following specific steps of (1) preparing a base cloth; (2) preparing PVC slurry; (3) penetrating the pvc slurry on the base cloth; (4) carrying out pvc film adhesion on the base cloth subjected tothe step (3) through a coating machine; and (5) drying the base cloth after the step (4), then transferring the base cloth into a surface machine through a guide wheel, and coating the base cloth witha polyvinylidene fluoride coating layer to obtain the anti-wicking building membrane material. The production technology is simple in step; the production cost of the building membrane materials is greatly decreased; compared with a traditional product, the prepared building membrane material has the advantages of being resistant to wicking performance, and outstanding in air tightness, effectively reducing the pore diameter characteristic of a fabric and the wicking effect caused by the fabric structure, and solving the problems of cracking, mildewing and the like of the materials caused bythe fact that external moisture enters the interior through the wicking effect; the durability of the product is improved; and the service life is greatly prolonged.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of building materials, in particular to a production process of an anti-wicking building membrane. Background technique [0002] As an emerging industry, architectural membrane materials have strong advantages and broad market prospects. With their advantages of lightness and beauty, light transmission and energy saving, safety and durability, artistic environmental protection, etc., they are widely used in various large-scale construction projects, such as large stadiums. , commercial public facilities, amusement parks, exhibition halls, airport halls, railway stations and other large facilities. Architectural membrane is known as the fifth building material after steel, cement, wood and glass. It can not only be used in the application fields of original building materials, but also in areas where the original building materials are difficult to apply, such as large-span In terms...
