Manufacturing method of rubber and chemical fiber synthetic waterproof sheet and product thereof

Abstract

The invention relates to a manufacturing method of a rubber and chemical fiber synthetic waterproof sheet and a product thereof, and the rubber and chemical fiber synthetic waterproof sheet is formed by compounding three layers of material, wherein the middle layer is a chemical fiber cloth or felt composite layer, and the chemical fiber cloth or felt composite layer is a waterproof layer enabling polymer synthetic rubber composite material and chemical fiber cloth or felt to infiltrate and adhere mutually; when in manufacturing, the chemical fiber cloth or felt of the middle layer is firstlyplaced in a dip coating groove for enabling the chemical fiber cloth or felt to soak polymer synthetic rubber waterproof rubber material, and the middle sheet layer is further manufactured; and two layers of the chemical fiber cloth or felt are stuck on two surfaces of the middle sheet layer respectively, thereby forming the three-layer compound synthetic waterproof sheet. The polymer synthetic rubber waterproof rubber material takes rubber as main material, and a high polymer and other auxiliary materials are added for manufacturing the waterproof rubber material; the auxiliary materials comprise an accelerant, filling material, a softener, a cross-linking agent or an anti-aging agent; and the middle sheet layer can be manufactured by one of three forms respectively, namely the cold working method, the hot working method and the rolling method.

Description

technical field [0001] The present invention relates to a waterproof material production method and its products, in particular to a rubber chemical fiber synthetic waterproof sheet production method and its products; it is mainly used in the field of building waterproof materials and waterproof engineering, especially waterproof (roll) sheets application in practical engineering. Background technique [0002] Waterproof sheets (coils) and waterproof coatings are the main two series of waterproof materials, and waterproof sheets play a leading role in the application of building waterproofing in my country, and play an important role in building waterproofing projects. Wide range of waterproof materials. [0003] The current varieties of building waterproof sheet (roll) materials have developed from a single asphalt felt in the 1950s to dozens of new high-end and high-end waterproof sheets. Commonly used waterproof sheet (roll) materials can be generally divided into accord...

AI Technical Summary

Problems solved by technology

Its disadvantages are; (1) open flames at the construction site are likely to cause safety accidents

(2) These asphalt tellurites and plastic ointments can emit pungent toxic odors and seriously pollute the environment

Its disadvantages are: (1) Dangerous

The blowtorch is filled with gasoline, which can easily cause explosions and fires, and cause injury to workers. There are many such accidents and many serious losses have been caused.

(2) Damaged sheet

[0015] The polymer rubber waterproof sheet (roll) material is the most ideal material in the whole waterproof sheet (roll) material. It not only has enough deformation ability to adapt to the project, but also has aging resistance. It is also the best, but because the construction quality is often not guaranteed, which seriously affects the waterproof quality of the project, so the usage of this kind of sheet (coil) material has dropped sharply in recent years.

[0016] The reasons why the construction quality of rubber sheets cannot be guaranteed are as follows: (1) The surfaces of rubber sheets (rolls) on the market are all smooth, so it is difficult to stick them firmly

(2) In order to resist aging, most sheet (coil) materials (such as EPDM rubber coils, etc.) choose materials with a relatively saturated molecular structure of rubber, so the compatibility with adhesives is relatively poor, which affects the adhesion. Effect

(3) Most of the adhesives on the market now choose highly corrosive benzene-based fluxes, and benzene-containing adhesives are prohibited products on construction sites, and are also unpopular products for construction workers. Based on the above three reasons, the rubber is waterproof Sheet development curbed

[0019] The self-adhesive method can realize the cold construction method, no exhaust gas emission, and protect the environment of the construction site and the personal safety of the construction workers. Therefore, it has developed rapidly in recent years, but there are also the following weaknesses: (1) The construction method is not easy to master. Carefully paste it a little crookedly (this happens often) I want to take it off and resurface it, the coil has been deformed

(2) Low temperature cannot be used for construction, and construction below 10°C will become a problem, and it cannot be pasted

(3) The torn isolation bottom (membrane) is not only a waste, but also creates a lot of construction waste

Weaknesses are: (1) The waterproof layer fails to combine with the base layer and the waterproof task is entirely borne by the waterproof sheet. With such a large waterproof area, such a thin waterproof sheet (roll) material (generally ≤ 2mm) only needs one leak point, the entire The waterproof function of the waterproof layer is completely lost

(2) The coil itself is also damaged by mechanical fixing

(3) Because the entire waterproof layer is not pasted with the base layer, the waterproof layer is easily damaged and aged
