Problems solved by technology

However, due to the low surface chemical activity of polyester fiber, the technical key of sticking to rubber has not been solved, so that the existing production process cannot be realized, thus limiting the application of polyester fabric as a skeleton material on rubber dam bags

Embodiment Construction

[0060] Below in conjunction with accompanying drawing and with dam height dam height 1.6 meters, internal pressure ratio is 1.3 double-anchor formula 29 meters long rubber dam dam bag as embodiment, specifically elaborates the manufacturing process of the present invention:

[0061] A. Pretreatment of polyester fabric:

[0062] Select the PP1010 plain polyester canvas with both warp and weft strength indicators of 100kN / m and soak it in the pretreatment solution of water-soluble epoxy resin and acid curing agent for 100s; the formula ratio is as follows:

[0063] The ratio (mass ratio) of water-soluble epoxy resin WSR618: curing agent WSR905: water is 100:80:300;

[0064] After dipping, the heat treatment temperature of the polyester fabric is kept at 130°C for 150s.

[0065]

[0066] B. Viscosification treatment of polyester fabric:

[0067] Immerse the polyester canvas pretreated in step A in the resorcinol-formaldehyde-latex (RFL) viscosity-increasing treatment solution ...

Abstract

The invention relates to a production process of rubber dam bags, and particularly relates to a production process for manufacturing rubber dam bags by using polyester fabric as a framework material. Through dipping pretreatment of polyester fabric with water-soluble epoxy resin and tackifying process of the polyester fabric with resorcinol-formaldehyde-latex (RFL), transition matching with a sizing material of an adhesion layer and process parameter matching of the whole vulcanization process of the sizing material, the technical problems of low chemical polarity on the surface of the polyester fabric and difficult direct adhesion with the rubber are solved. Compared with the prior art, the rubber dam bags provided by the invention have the advantages of high strength, low elongation, good shape, light weight, aging resistance, good water resistance and convenience in transportation, installation and maintenance of dams, and possibility for producing rubber dam bags with high performance and improving the height of rubber dams is provided.

Description

technical field [0001] The invention relates to a production process of a rubber dam bag. Background technique [0002] Compared with traditional concrete dams, rubber dams have many characteristics such as saving three materials, low cost, short construction period, flexible use, good earthquake resistance, and convenient management. They can be used for flood control, irrigation, power generation, water supply, shipping, tide protection, gardening Water conservancy projects such as landscaping and movable cofferdams. The rubber dam bag is the functional main part of the rubber dam, and its skeleton material has experienced the development process from cotton canvas, vinylon fabric to nylon fabric. At present, nylon canvas is the most common in engineering applications. For example, the rubber dam bags produced by the former Shenyang Fourth Rubber Factory since 1973 and used at home and abroad are all made of resorcinol-formaldehyde-latex once. The impregnated nylon canva...
