Problems solved by technology

[0006] The technical problem to be solved by the present invention: the current ordinary FRP materials are easy to cause damage under burning, high temperature and other environments, and at the same time, the interlayer strength is borne by resin, and the strength is low. In addition, the mutual friction of ordinary FRP materials will generate static electricity. , if the static electricity is not effectively released, sparks will be generated, resulting in the defect of spontaneous combustion of the material, and a preparation method of high-strength antistatic FRP material is provided

example 1

[0022]Weigh 80g of wollastonite and put it into a high-temperature furnace, calcinate at 850°C for 1 hour, grind and discharge the material to obtain calcined wollastonite powder, and mix the calcined wollastonite powder and deionized water at a mass ratio of 1:3 Place in a four-necked flask equipped with a thermometer, a condenser and a stirrer, and stir for 10 minutes in an ice-water bath at 0°C. After stirring, add 2 mL of anhydrous tin tetrachloride dropwise to the four-necked flask, and continue stirring for 24 minutes. The reaction solution was obtained, and the pH value of the reaction solution was adjusted to 8-10 with ammonia water with a mass fraction of 15%. After adjustment, the temperature was raised to 25° C., and kept for 35 minutes to obtain a precipitate, and the filtrate was filtered to obtain a filter residue, which was washed with deionized water. Filter the residue 3 times, and finally put it into an oven, dry it at 75°C for 20 minutes, put it into a high-t...

Abstract

The invention relates to the technical field of preparation of high polymer materials, in particular to a preparation method of a high-strength and anti-static fiber reinforced plastic material. The high-strength and anti-static fiber reinforced plastic material is prepared from modified epoxy resin as a matrix, glass fibers and modified wollastonite powder as reinforcing agents as well as phthalic anhydride, p-phenylenediamine and other components for assistance; cyanate ester resin and self-made silica sol are used for modifying bisphenol A epoxy resin, then silica sol is prepared with a tetraethoxysilane hydrolysis method, so that high-temperature resistance of the fiber reinforced plastic material is improved; besides, the self-made silica sol prepared from tetraethoxysilane and othersubstances has good electrical conductivity, static electricity on the surface of the fiber reinforced plastic material can be carried away, static removal effect is realized, and antistatic propertyof the fiber reinforced plastic material is improved; the glass fibers are added to the matrix continuously, the glass fibers are connected through staggered matrix molecular chains, accordingly, strength of the fiber reinforced plastic material is improved, and the fiber reinforced plastic material has broad application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a preparation method of high-strength antistatic FRP material. Background technique [0002] FRP, also known as glass fiber or fiber reinforced plastic, is a composite material made of high molecular weight epoxy resin or unsaturated polyester resin as a matrix, glass fiber, carbon fiber or boron fiber as a reinforcing material, and made through a composite process. . It is the largest and most widely used composite material in the world, and it occupies a dominant position in the use of composite materials. [0003] FRP has many advantages that other materials cannot match, such as: small specific density, high specific strength, easy forming, corrosion resistance, high temperature resistance, good electrical insulation, etc., has been used in aerospace, railways, decorative buildings, home furniture, etc. , advertising display, craft gifts, building m...
