Problems solved by technology

But the coated fabric of the prior art can not have good water resistance and anti-ultraviolet ability, and long-term use outdoors is easy to age, only the problem such as fabric surface coating falls off, and the strength of general coated fabric is not high, long-term There will be tears and holes after time use

Embodiment 1

[0028] A water-resistant non-woven fabric with epoxy resin coating in this embodiment includes a base layer, and the base layer includes at least two layers of non-woven fabrics, and the adjacent non-woven fabrics have a size of CNP50-5× 5, and the adjacent non-woven fabric layers are filled with glue as an adhesive, and the outside of the base layer is also wrapped with a waterproof base layer, and the waterproof base layer is hydroxymethyl bisphenol A epoxy resin. The woven fabric is a blended non-woven fabric of polytetrafluoroethylene fiber and polyparaphenylene terephthalamide fiber, in which the mass percentage of polytetrafluoroethylene fiber is 37-51%, and polytetrafluoroethylene diamide fiber is 37-51%. The mass percentage of the diamine fiber is 49%-63%, and the glue components are ethylene-vinyl acetate copolymer, butyl rubber, butylphenol resin, dibutyl phthalate and calcium carbonate.

[0029] Preparation method of the present invention, concrete steps are:

Abstract

The invention discloses a method for preparing a water-resistant non-woven fabric material with an epoxy resin coating. The method comprises the following steps: 1) preparing a hydroxymethyl bisphenol A epoxy resin material required by a waterproof base layer, adding a flexibilizer carboxyl liquid nitrile rubber in the hydroxymethyl bisphenol A epoxy resin material to form the waterproof base layer for standby; 2) using a raw material to prepare a fabric glue for standby; 3) taking a polytetrafluoroethylene fiber polymer and a poly-p-phenylene terephthamide fiber polymer, then blending the materials to prepare non-woven fabrics for standby; 4) preparing the base layer; 5) placing the prepared base layer in a phenylethyl salicylate solution for standing, then taking the base layer out and placing the base layer under normal temperature; and 6) uniformly smearing the prepared waterproof base layer at the external part of the base layer, performing secondary hot pressing, and finally cutting and moulding to obtain the product. A solidification object obtained by solidifying an epoxy resin composition obtained by the waterproof base layer has the excellent moisture resistance and heat resistance.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a method for preparing water-resistant non-woven fabrics with epoxy resin coating. Background technique [0002] Because of the cheap price, people usually use colored plastic films to make waterproof and rain-proof ceilings, but the strength of the plastic films is too low, it is easy to be scratched, and the shading is not good. Later, impermeable fabrics were invented to waterproof, Rain protection, strong and durable. There are many types of fabrics with waterproof function in the market. Although some types have good waterproof effect, they have poor flexibility, poor air permeability, and lack of oil resistance. [0003] However, in the existing technical solutions, more coated fabrics are used. The coated fabric is a kind of textile, and the coating adhesive material forms a single-layer or multi-layer coating in situ on one side of the fabric or on the front and back sid...
