AI Technical Summary

Problems solved by technology

However, existing stone-plastic products and their production, processing, recycling, etc. have many technical problems that need to be solved urgently. For example, stone powder should be as fine as possible, which can not only improve the filling effect of stone powder in plastic products, but also ensure the ability to increase strength. At the same time, the refined stone powder can avoid increasing the difficulty of recycling and granulating plastic products; after all, stone powder and plastic are incompatible systems, and the amount of stone powder added should not be too much. Too much will easily lead to a decrease in strength, or molding difficulties

Abstract

The invention belongs to the technical field of composite material and specifically relates to a stone-plastic compound fan blade and a preparation method thereof. The preparation method comprises thesteps: (1) adding limestone powder into coal gangue and performing roasting treatment to obtain roasted things; (2) dispersing a silane coupling agent into water, adding the roasted things in the step (1), performing ultrasonic dispersion treatment and performing drying and screening treatment to obtain plastic particles; (3) feeding the plastic particles, matrix resin and other additives into anextruding machine through a weight loss scale, wherein the matrix resin and the other additives are used for preparing the stone-plastic compound fan blade; evenly dispersing the plastic particles into the matrix resin through shearing and mixing of a screw rod to obtain a fused mixture, then extruding the fused mixture into a mould and cooling and shaping to obtain the stone-plastic compound fanblade. In the stone-plastic compound fan blade disclosed by the invention, the coal gangue is refined, the coal gangue is utilized as filler to be added into the matrix resin to prepare the stone-plastic compound fan blade, and the strength of the stone-plastic compound fan blade is improved.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a stone-plastic composite fan blade and a preparation method thereof. Background technique [0002] The working principle of the electric fan is to use the AC motor to convert electrical energy into mechanical energy. The AC motor drives the fan blades to rotate to promote air flow, promote the rapid evaporation of sweat on the surface of the human skin, and combine the principle of evaporation and heat absorption to make people feel cool. Compared with air conditioners, the power consumption of electric fans is very low, which is the best choice for cooling in summer. Generally speaking, when all configurations are the same, metal (usually aluminum alloy) fan blades are harder and more stable than plastic fan blades, and the air output is stronger and more stable; the cost of plastic fan blades Low cost is the key. If it is not a high-power fan, the cost...
