Problems solved by technology

This type of board can make excellent use of waste industrial plastics to make recycled resources, but because the resin fiber is a mixture of polymer and glass fiber, it is not easy to be bonded by ordinary adhesives, even if it is barely bonded, this type of board It is very easy to have bad phenomena such as particle loosening and low internal bonding strength, and the stretch resistance, waterproof and wear resistance are extremely poor

Embodiment 1

[0042] A resin composite plate, comprising the following raw materials in weight percentage: 30-50% of plastic powder, 40-55% of resin fiber powder, 8-25% of BR, 3-5% of fiber adhesive, and 0.2-0.4% of triphenyl phosphite.

[0043] In order to achieve the best effect of the board, the weight percentage of each raw material should be kept as follows: plastic powder 30, resin fiber powder 50, BR14.6, fiber adhesive 5, triphenyl phosphite 0.4. Production method: in the present embodiment, as shown in accompanying drawing 1, the present invention takes resin fiber powder as main raw material, adds plastic powder as auxiliary raw material, and fully mixes after two powder materials are dried respectively, then adds BR cement, fiber glue Mixture and modifier triphenyl phosphite, each powder is fully mixed, placed in a mold with a gauge pressure of 10KPa to 20Kpa at 190°C to 250°C, and pressed into a mold. The formed board is made of BR adhesive , Fiber adhesive glued and added a pro...

Embodiment 2

[0045]A resin composite board, comprising the following raw materials in weight percent: 20-30% plastic powder, 50-70% resin fiber powder, 7-20% adhesive, and 2-15% modifier; the adhesive is phenolic resin, and the The modifying agent is a mixture of aluminum hydroxide, calcium stearate and nano-calcium carbonate.

[0046] The optimum weight percentages of the above raw materials are: plastic powder 20, resin fiber powder 50, phenolic resin 15, aluminum hydroxide 4, calcium stearate 3, nanometer calcium carbonate 8.

[0047] In this embodiment, the modifier calcium stearate and nano-calcium carbonate are used to effectively increase the toughness of the board and prevent the board from being easily crushed due to excessive rigidity, and the nano-calcium carbonate is used as a fine filler to effectively fill the plastic powder The gap between the resin fiber powder and the resin fiber powder makes the bonding effect of the board better and can form a smooth surface on the surfa...

Embodiment 3

[0049] A resin composite board, comprising the following raw materials in weight percent: 20-30% plastic powder, 30-50% resin fiber powder, 8-25% adhesive, and 15-20% modifier; the adhesive is phenolic resin, and the The modifier described above is wood fiber powder.

[0050] The optimum weight percent of above-mentioned raw material is: plastic powder 20, resin fiber powder 50, phenolic resin 15, wood fiber powder 15.

Abstract

The composite resin plate is made of material including plastic powder 20-60 wt%, resin fiber powder 30-70 wt%, adhesive 7-25 wt% and modifier 0.2-25 wt%. The adhesive is one or several of cis-butadiene adhesive, fiber adhesive, BR, phenolic acid resin and uric acid resin; and the modifier is one or several of lignocellulose powder, aluminum hydroxide, calcium stearate, triphenyl phosphite and nanometer calcium carbonate. The present invention adds proper adhesive and modifier in treating waste resin fiber powder and uses plastic powder as supplementary material to make the composite resin plate heat resistant, fireproof, waterproof, anticorrosive, mildewproof, tension resistant, wear resistant and widely applicable.

Description

technical field [0001] The invention relates to the technical field of composite sheet manufacturing, in particular to a composite sheet formed by pressing industrial waste. Background technique [0002] At present, with the promotion of the world economy, various industries have been greatly developed, especially in the communication electronics industry, which has brought about serious electronic waste pollution problems while driving the national economy of our country. Industrial waste --- resin fiber powder, because the main component of resin fiber is a mixture of polymer and glass fiber, and these polymers are difficult to be reduced and decomposed after polymerization and curing. The environmental treatment of industrial waste that cannot be degraded naturally has brought great difficulties. There are also composite boards made of other industrial wastes (waste plastics), such as the patent document named as Chinese Patent No. 03212613.1, which reports the use of di...
