preparation example Construction

[0017] A preparation method for a container plate, comprising:

[0018] Prepare the first resin. The first resin is selected from unsaturated polyester resins. The unsaturated polyester resin can be selected from at least one of phthalic acid type unsaturated polyester, isophthalic acid type unsaturated polyester, bisphenol A type unsaturated polyester and vinyl ester type unsaturated polyester . For example, the unsaturated polyester resin may be specifically, for example, type 191 resin, type 196 resin, type 197 resin, or type 198 resin.

[0019] Prepare curing agent. The curing agent is selected from methyl ethyl ketone peroxide, and the unsaturated polyester resin is triggered by the methyl ethyl ketone peroxide to accelerate the curing of the unsaturated polyester resin.

[0020] Get accelerators. The accelerator is selected from colorless cobalt water, and the colorless cobalt water is a colorless accelerator for curing molding of unsaturated polyester resin at 20-2...

Embodiment 1

[0056] After mixing 28kg of bisphenol A type unsaturated polyester, 1kg of methyl ethyl ketone peroxide, 0.06kg of colorless cobalt water, 3kg of aluminum hydroxide and 3kg of magnesium hydroxide, at a temperature of 50 ° C, the above The mixture of materials flows naturally into a layer of uniform thickness, which is the resin pool.

[0057] 32 kg of short basalt fiber filaments with a length of 5 cm were scattered in the resin pool. 9kg of gel coat resin and 2kg of titanium dioxide were evenly mixed to obtain the second resin. The second resin is spray-coated on the surface of the short basalt fiber.

[0058] After the surface of the second resin is covered with a film, roll extrusion is carried out.

[0059] The extruded product of the press roll is heated in the first heating section at a temperature of 80°C, the second heating section at a temperature of 80°C and the third heating section at a temperature of 50°C, and used in the first heating section and the second hea...

Embodiment 2

[0061] After mixing 33kg of bisphenol A type unsaturated polyester, 2.7kg of methyl ethyl ketone peroxide, 0.09kg of colorless cobalt water, 4.5kg of aluminum hydroxide and 3kg of magnesium hydroxide, at a temperature of 50°C, The mixture of the above materials flows naturally into a uniform thickness adhesive layer, which is the resin pool.

[0062] 40 kg of short basalt fiber filaments with a length of 5 cm were scattered in the resin pool. 11kg of gel coat resin and 3kg of titanium dioxide were evenly mixed to obtain the second resin. The second resin is spray-coated on the surface of the short basalt fiber.

[0063] After the surface of the second resin is covered with a film, roll extrusion is carried out.

[0064] The extruded product of the press roll is heated in the first heating section at a temperature of 78°C, the second heating section at a temperature of 80°C and the third heating section at a temperature of 50°C, and used in the first heating section and the s...

Abstract

The invention provides a container plate and a preparation method thereof, and relates to the field of basalt fiber. The preparation method of the container plate comprises: mixing the first resin and a curing agent to obtain a resin pool, laying cloth in the resin pool, scattering basalt fibers in the resin pool and distributing them on the cloth, spraying the second resin on the basalt fibers, and The second resin covers the film, roll extrusion and thermoforming. The container board uses basalt fiber as the skeleton material, which has the characteristics of good flame retardancy, strong corrosion resistance and light weight of basalt fiber, and at the same time, has high mechanical strength.

Description

technical field [0001] The invention relates to the field of basalt fibers, and in particular to a container board and a preparation method thereof. Background technique [0002] Basalt fiber has excellent properties: [0003] ⑴Chemical properties: basalt fiber contains K 2 O, MgO, and TiO 2 , so that basalt fiber has better acid resistance, alkali resistance and water resistance than alkali-free glass fiber; [0004] (2) Physical properties: Basalt is a refractory ore with a melting temperature of 1500°C and a sintering temperature of 1060°C, which makes basalt fiber have excellent high and low temperature resistance. In addition, basalt fiber also has good sound insulation and heat insulation properties And electrical insulation properties; most importantly, the tensile strength and elastic modulus of basalt fiber are higher than that of alkali-free glass fiber or glass fiber, and have better mechanical strength. [0005] At present, although the existing container mat...
