Problems solved by technology

[0005] The inside of the coated fabric used in the prior art is generally coated with polyurethane elastomer or nitrile rubber and its composite glue, but because the polyurethane elastomer coating or nitrile rubber and its composite glue coating are easy to carry out two-way substances with the stored oil. Exchange, that is, oil molecules leak through the inner coating of polyurethane elastomer coating or nitrile rubber and its composite rubber coating to cause oil leakage, and at the same time, small molecules such as additives and auxiliary agents in the inner coating are leached by oil The oil is sucked into the inner coating to pollute the oil, so the soft oil tanks made of known coated fabrics have at least the following disadvantages: poor oil resistance, easy to seep out of the oil; Coating leached out into stored oil causing oil contamination
[0006] In addition, it is known that soft oil tanks made of coated fabrics generally have poor weather resistance. For example, under high temperatures above 60°C and / or ultraviolet radiation, the coated fabrics are prone to rupture and cause damage to the soft oil tanks, making them unusable
Moreover, under the condition of high temperature and high surface tension, the two-way penetration of the above-mentioned oil material and the inner coating material is more serious, and the oil material exuded and diffused to the outer coating of the coated fabric is subjected to high temperature, high surface tension and ultraviolet rays. The combined damage of the soft oil tank will aggravate the aging of the coated fabric of the soft oil tank and drastically reduce its service life

Embodiment 1

[0036] Example 1: Preparation of super oil resistant coated fabric

[0037] First, the fiber reinforcement layer woven into high-strength polyester square fabric is dipped (121 parts of epoxy resin E81, 10 parts by weight of phenol-blocked MDI, 40 parts by weight of 40% butylpyridine latex, 50 parts by weight of water) and processed at 230 ° C. After the qualitative type, the polyether thermoplastic polyurethane elastomer (produced by Yantai Wanhua Polyurethane Co., Ltd.) is melt-coated on the upper primer layer to form an outer coating, and the polyester thermoplastic polyurethane elastomer (Yantai Wanhua Polyurethane Co., Ltd. Produced by the company) is melt-coated on the lower base coat to form an inner coat to prepare oil-resistant coated fabrics. The inner coating of this oil-resistant type coated fabric is scraped and coated with two-component polyurethane adhesive (100 parts by weight of polyethylene adipate glycol and 8 parts by weight of toluene diisocyanate and 30...

[0038] Example 2: Preparation of super oil resistant coated fabric

[0039] Prepare as described in Example 1, except that the polyvinyl fluoride film produced by Zhejiang Lantian Environmental Protection High-Tech Co., Ltd. is used instead of the PVF film produced by DuPont get as figure 1 Super oil resistant coated fabric shown.

Embodiment 3

[0040] Example 3: Preparation of super oil resistant coated fabric

[0041] First, the fiber reinforced layer woven into high-strength nylon square fabric is dipped (1 part of epoxy resin E812, 10 parts by weight of phenol-blocked MDI, 40 parts by weight of 40% butylpyridine latex, 50 parts by weight of water) and treated at 230 ° C. After heat-setting, the composite glue of nitrile rubber and polyvinyl chloride is pasted on the upper and lower primer coats to form an outer coat and an inner coat respectively, and an oil-resistant coated fabric is prepared. The inner coating of this oil-resistant type coated fabric is scraped-coated with acrylonitrile-butadiene rubber-based adhesive (40-100 parts by weight of nitrile, 30 parts by weight of ammonia water catalytic phenolic resin, 25 parts by weight of magnesium oxide, 5 parts by weight of tricumyl peroxide parts by weight, 10 parts by weight of carbon black, 800 parts by weight of ethyl acetate), after drying for 60 seconds a...

Abstract

The invention discloses a method for preparing ultra oil-resistant coated fabric and ultra oil-resistant coated fabric prepared by using the method. The preparation method mainly includes the steps offorming an oil-resistant diffusion layer on an internal coating of the oil-resistant coated fabric. A fluororesin film, preferably a polyvinyl fluoride film or a polyvinylidene fluoride film, can beused as the oil-resistant diffusion layer. The obtained ultra oil-resistant coated fabric has excellent oil resistance and weather fastness, and a membraneous oil tank made from the coated fabric hasextremely slight pollution to stored oils.

Description

technical field [0001] The invention relates to the field of materials, in particular to a method for preparing an oil-resistant coated fabric, and the resulting product and application thereof. Background technique [0002] As fuel, oil is an important energy material for civil and military use, and the storage and transportation of oil are extremely important. Oil storage devices such as metal oil tanks and oil pipelines for long-distance transportation are expensive, and because of factors such as their weight, large volume, and difficulty in fixing, they can only be used for fixed purposes and are not suitable for mobile use. [0003] In order to adapt to the convenient use of civilian and military oil, a variety of light soft oil tanks have been developed. These oil tanks are generally made of organic polymer materials, with large storage volume, foldable, easy to use, easy to transport, and relatively low cost. Low. As long as the oil is filled into it, it can be use...
