Embodiment 1

[0034] Such as figure 1 As shown, the preparation method of the epoxy and PVC composite flexible veneer material described in this embodiment, first, prepare two components of epoxy coating respectively, wherein the weight percentage of component A is composed of: 55% epoxy resin E -44, 30% talc, 5% butyl glycidyl ether, 3% carboxy-terminated nitrile rubber, 0.3% polyacrylate copolymer, 0.3% polyorganosiloxane, 2.4% polydimethylsiloxane and 4% color paste. The weight percentage of component B is composed of: 93% polyamide 300 type (amine value 465mgKOH / 100g, viscosity 6-20pa.s / 25°C) and 7% 2,4,6-tris(dimethylaminomethyl )phenol. Mix A component and B component at a weight ratio of 10:3 to prepare an epoxy coating.

[0035] Utilize the coating machine to uniformly coat the epoxy coating on the glass fiber cloth layer of the PVC glass fiber cloth composite coating layer, the thickness of the epoxy coating is generally between 0.1-0.7mm, and then bake at 90°C for 20 Minutes, ...

Embodiment 2

[0037] Such as figure 1 As shown, the preparation method of the epoxy and PVC composite flexible veneer material described in this example first prepares two components of epoxy coating respectively, wherein the weight percentage of component A is composed of: 50% epoxy resin E- 51. 30% talc, 8% butyl glycidyl ether, 5% liquid nitrile rubber, 0.5% polyether modified silicone oil, 0.2% silicone, 1.3% polydimethylsiloxane And 5% color paste. Component B consists of 97% modified alicyclic amine curing agent (amine value 400-600mgKOH / 100g, viscosity 300-600mpa.s / 25°C) and 3% benzyldimethylamine. Mix A component and B component at a weight ratio of 10:2 to prepare an epoxy coating.

[0038] Utilize the coating machine to evenly coat the epoxy coating on the glass fiber cloth layer of the PVC glass fiber cloth composite coating layer. Minutes, and finally cooled, trimmed, and rolled to make a flexible veneer material composited with epoxy and PVC.

Abstract

The invention discloses a method for preparing an epoxy and polyvinyl chloride (PVC) composite flexible faced material, which comprises the following steps of: preparing an epoxy coating by weighing, baiting and stirring, uniformly coating the epoxy coating on the surface of glass fiber cloth of a PVC glass fiber composite coating through a coater, then baking for 15 to 20 minutes at the temperature of between 90 and 120 DEG C, and finally cooling, trimming and coiling to obtain the epoxy and PVC composite flexible faced material. Specific raw materials and proportion of the raw materials are adopted in the method; and the produced epoxy and PVC composite flexible faced material has excellent physical and chemical properties of epoxy resin such as abrasion resistance, scouring resistance, grease dirt resistance, ageing resistance, strong chemical resistance, strong adhesive force and the like. Because the PVC coating with good flexibility is used as a bottom material coating, flexibility and easy sticking property of the faced material are increased. By using glass fibers as a material skeleton, the material is further enhanced, and the problems of frangibility, easy cracking and the like of most faced materials are solved.

Description

technical field [0001] The invention relates to a veneer material, in particular to a flexible veneer material compounded with epoxy and PVC and a preparation method thereof. Background technique [0002] Epoxy coatings are thermosetting materials known worldwide for their superior performance and wide range of applications. Epoxy resin wall, floor and other coatings rely on mechanical or manual coating of epoxy resin coatings on the surface of walls, floors, etc. and wait until it is completely cured, so as to form a seamless, dust-free, strong, high-quality coating on the surface of the ground. Wear-resistant, acid and alkali corrosion-resistant protective layer, but this construction method is more complicated, and the curing time of epoxy coating is long after construction, and harmful substances are volatilized during the curing process. In addition, PVC is a thermoplastic material with good plasticity, flexibility, and resilience. But the composite of epoxy resin and...
