Problems solved by technology

However, the high glue content of sisal fiber, especially the high lignin content, makes the fiber breaking strength higher, the rigidity is large, and the elasticity and elongation are small. Weaving is inconvenient. On the other hand, the waterproof cloth obtained is hard, which affects the scope of use.

Abstract

The invention discloses sisal waterproof cloth, which is prepared as follows: weaving sisal fiber into base cloth, then putting the base cloth into epoxy soybean oil for soaking for 3 to 5 minutes, taking the base cloth out, coating the front side and the back side of the base cloth with a coating material, putting the base cloth into a drying oven for plasticizing at 80-90 DEG C to obtain the sisal waterproof cloth, wherein the coating material comprises the following raw materials in parts by weight: 100 parts of polyvinyl chloride paste resin, 8 parts of titanium dioxide, 20 parts of water, 1 part of pentachlorophenol, 6 parts of polyoxyethylene castor oil, 10 parts of pentaerythritol and 30 parts of dimethyl phthalate. By multiple times of injection of a sulfuric acid solution and vacuumizing operation and combined treatment of a sodium persulfate solution, a sodium hydroxide solution and ultrasonic wave, colloid in sisal fiber can be thoroughly removed, and the obtained waterproof cloth is soft.

Description

technical field [0001] The invention relates to a waterproof cloth. More specifically, the present invention relates to a tarpaulin woven from sisal fibers. Background technique [0002] Sisal is a perennial tropical hard leaf fiber crop, which has the advantages of long fiber, tough texture, friction resistance, tear resistance, salt and alkali resistance, corrosion resistance, low temperature resistance, and little flexibility in dry and wet environments. If sisal fibers are used to make tarpaulins, the mechanical properties of tarpaulins will be greatly improved, and the application of sisal hemp will also be expanded. However, the high glue content of sisal fiber, especially the high lignin content, makes the fiber breaking strength higher, the rigidity is large, and the elasticity and elongation are small. Weaving is inconvenient, and on the other hand, the obtained tarpaulin is hard in texture, which affects the scope of use. Therefore, urgently need to design a kin...
