Problems solved by technology

Although the body made of these metal materials can meet the requirements of strength, rigidity, etc., its production cost is high, the production cycle is long and the body is too heavy, which causes a large energy consumption during use.
In the prior art, some cars are also made of carbon fiber, but the price of carbon fiber is too expensive, which is not conducive to widespread promotion

preparation example Construction

[0025] The invention provides a kind of preparation method of basalt composite material, comprises the following steps:

[0026] a) mixing the resin material with the curing agent to obtain a colloidal solution;

[0027] b) fully contacting the colloidal solution obtained in step a) with basalt fibers under vacuum conditions, and then curing to obtain a basalt composite material;

[0028] The monofilament diameter of the basalt fiber is 6 μm to 15 μm, and the surface density is 270 g / m 2 ~330g / m 2 ;

[0029] The mass ratio of the colloid solution to the basalt fiber is (2.6-4.3):7.5.

[0030] In the present invention, firstly, the resin material and the curing agent are mixed to obtain a colloidal solution. In the present invention, the resin material is preferably selected from one or more of vinyl resins, epoxy resins, polyurethane resins and phenolic resins, more preferably epoxy resins or phenolic resins. The present invention has no special limitation on the source o...

Embodiment 1

[0054] Wipe the surface of the mold with 1.5 parts by weight of release agent, and then lay 75 parts by weight of cut basalt fiber cloth on the mold, then cover the release cloth in turn, spread the diversion net, lay the vacuum film, and then vacuumize To a vacuum degree of 0.092MPa ~ 0.095MPa;

[0055] The phenolic resin of 25 parts by weight and the hexahydrophthalic anhydride of 5 parts by weight are mixed uniformly in the resin tank to form a colloidal solution, and then the above-mentioned colloidal solution is immersed in the mold through a draft tube to make the basalt fiber cloth in the mold Fully contact with the colloidal solution;

[0056] After the above-mentioned mold is completely immersed in the colloidal solution, put it into an oven and cure it at 50°C for 2 hours, then take out the mold and demold it to obtain a basalt composite material;

[0057] The obtained basalt composite material is scored, cut, polished, repaired and assembled to further obtain a toy...

Embodiment 2

[0059] Wipe the surface of the mold with 1.5 parts by weight of release agent, and then lay 75 parts by weight of cut basalt fiber cloth on the mold, then cover the release cloth in turn, spread the diversion net, lay the vacuum film, and then vacuumize To a vacuum degree of 0.092MPa ~ 0.095MPa;

[0060] Mix 25 parts by weight of epoxy resin and 5 parts by weight of 4,4'-diaminodiphenylmethane in a resin tank to form a colloidal solution, and then immerse the above colloidal solution into the mold through a draft tube, so that The basalt fiber cloth in the mold fully contacts with the colloidal solution;

[0061] After the above-mentioned mold is completely immersed in the colloidal solution, put it into an oven and cure it at 90°C for 2 hours, then take out the mold and demold it to obtain a basalt composite material;

[0062] The obtained basalt composite material is scored, cut, polished, repaired and assembled to further obtain a toy car body.

Abstract

The invention provides a preparation method of a basalt composite material. The preparation method comprises the following steps: a) mixing a resin material with a curing agent to obtain a colloidal solution; and b) fully contacting the colloidal solution obtained in step a) with basalt fibers under a vacuum condition, and then performing curing to obtain the basalt composite material, wherein themonofilament diameter of the basalt fibers is 6-15 [mu]m, and the areal density is 270-330 g/m<2>; and a mass ratio of the colloidal solution to the basalt fibers is (2.6-4.3):7.5. Compared with theprior art, the preparation method allows the basalt composite material to be prepared by adopting the basalt fibers as a matrix material and adopting specific technologies and conditions; and the basalt composite material obtained by the preparation method has the advantages of light mass, high strength, high extension and moderate price, and is suitable for being applied as a toy car body material.

Description

technical field [0001] The invention relates to the technical field of composite materials, and more specifically relates to a basalt composite material and its preparation method and application. Background technique [0002] In recent years, with the intensified consumption of non-renewable energy such as steel and petroleum, the development of resources has become more and more tense, so it is particularly important to develop materials that can replace steel. [0003] Basalt fiber is a kind of inorganic environmental protection green high-performance fiber, which not only has good stability but also has good electrical insulation, corrosion resistance, combustion resistance, high temperature resistance, high strength and other excellent properties. In addition, the production process of basalt fiber produces less waste and less pollution to the environment. After the product is discarded, it can be directly transferred to the ecological environment, realizing the true se...
