Pressed stiffening plate prepared by utilizing recovered reinforced plastic glass fibre scrap material and process thereof

Abstract

The invention relates to a pressed stiffening plate prepared by utilizing a recovered reinforced plastic glass fibre scrap material and a process thereof. The pressed stiffening plate takes the recovered reinforced plastic glass fibre scrap material as the major ingredient comprising the following components in percentage by weight: 12-16% of high-temperature resin, 65-70% of the reinforced plastic glass fibre scrap material and 18-22% of scrap particles and/ or polishing dust of a p-phthalate unsaturated polyester pouring material, and the moisture content of the reinforced plastic glass fibre scrap material is less than or equal to 1%; and the auxiliary material is a resin additive with the high-temperature resin amount of is 2-5%. The preparation process comprises: weighting the components for standby; adding the reinforced plastic glass fibre scrap material into a stirred tank first; stirring by utilizing a mixer; adding the scrap particles and/ or polishing dust of the p-phthalate unsaturated polyester pouring material into the stirred tank; then, adding the high-temperature resin; mixing evenly to form a stiffening plate premix; heating a mould until the temperature thereof is 160-170 DEG C; coating release agent in the mould; putting the stiffening plate premix into the mould, and flattening the stiffening plate premix; and pressing and shaping the stiffening plate premix by utilizing a press. The invention has the advantages of effectively recovering the plastic glass fibre scrap material, reducing environment pollution and saving the amount of outsourced stiffening plates.

Description

technical field [0001] The invention relates to the field of waste recycling and reuse of refractory materials, in particular to a pressed reinforcement plate prepared by recycling glass fiber reinforced plastic fiber waste and a process thereof. Background technique [0002] After the fiberglass waste is generated, it needs to occupy a large space due to its different sizes and shapes, and it cannot be degraded at all in the natural environment. The traditional treatment method is burning, the black smoke soars into the sky, and the smell is unbearable; the second is deep burying, which not only takes up a lot of space, but also never rots, and toxic substances will be precipitated. [0003] Today's society requires the use of ecological laws rather than mechanistic laws to guide the economic activities of human society. The difference between the traditional economy and the circular economy is that the traditional economy is a linear economy with a one-way flow of "resour...
