Nano PVC flame-retardant waterproof tarpaulin and preparation method thereof

Abstract

The invention discloses nano PVC flame-retardant waterproof tarpaulin and a preparation method thereof. The nano PVC flame-retardant waterproof tarpaulin is prepared by the steps that a synthetic fiber base cloth is dipped with PVC nano flame-retardant plasticizing paste, particles with very small nano-penetrant penetrate completely into the fiber gaps of the base cloth, and then the base cloth isflattened by a flattening machine and is heated and plasticized by a drying oven to prepare into a covering film with smooth two sides, so that the tarpaulin is quite high in water permeability resistance. The problems that in the prior art, the tarpaulin covering film is easy to fall off and skin is broken are solved. According to the formula, synthetic plant fatty acid ester with the flame retardant property, and polishing slag with flame retardant and smoke suppression performance are added, so that the problem that the flame retardant performance is reduced due to the addition of a largenumber of small molecule plasticizers in the prior art is solved. The polishing slag is added in a large amount as inorganic filler, so that the production cost is reduced, the flame-retardant and smoke suppression performance of the PVC flame-retardant waterproof tarpaulin is improved, and the problem of environmental pollution caused by waste landfill due to difficult recycling of stone, ceramictiles and artificial stone polishing residues is solved.

Description

technical field [0001] The invention relates to the field of waterproof materials, and mainly relates to a nano-PVC flame-retardant waterproof, tarpaulin and a preparation method. Background technique [0002] PVC flame retardant and waterproof, tarpaulin is an indispensable protective equipment for industry, agriculture, engineering projects, and outdoor covering. The waterproof and tarpaulins of the prior art are based on synthetic fiber canvas, coated with PVC paste resin, mixed with plasticizers, anti-mold agents, flame retardants and other raw materials, and plasticized at high temperature. become. The bonding strength between synthetic fibers and PVC is low. After a period of use, the PVC on the inner surface of the tarpaulin is easy to fall off and break. The chlorine content of PVC is as high as 56, and it has good flame retardancy. However, due to the addition of flammable small molecule plasticizers, the flame retardancy of the material is reduced. In order to me...

AI Technical Summary

Problems solved by technology

The PVC nano-flame-retardant plasticized paste of the present invention is added with a nano-penetrating agent, and the extremely small particles can completely penetrate into the fiber gaps of the synthetic fiber base cloth, and are flattened by a flattening machine and heated and plasticized by a heating oven to make double-sided Flat and smooth covering film, the covering film is integrated with the synthetic fiber base cloth, has high water permeability, and solves the problem that the PVC covering film on the inner surface of the waterproof tarpaulin in the prior art is easy to fall off and break.
