Problems solved by technology

In the field of plastic building materials, PVC decorative skirting is the most widely used in the traditional plastic-based decorative skirting, because it is the cheapest and can meet the surface texture and color requirements through surface skin, but because of its low hardness, it is relatively Easy to deform, easy to wear, easy to break
[0003] The traditional PVC decorative baseboard mainly uses calcium carbonate powder as filler to solve the disadvantages of low hardness, easy deformation, easy wear and breakage of PVC baseboard. It mainly comes from limestone mines. However, in recent years, with the environmental resources The increasing depletion of the country, the country has also strictly restricted the mining of mines, which also promotes the development of alternative resources for limestone minerals.

Abstract

The invention relates to a method for preparing an environment-friendly PVC decorative skirting line by using desulfurized ash. In this method, the desulfurization ash is weighed according to the formula and put into a high-speed mixer for stirring; then stearic acid and paraffin are added to the above-mentioned high-speed mixer for blending, and then a stabilizer and waste PVC powder are added to continue blending; finally, the uniformly mixed material Put it into the feed hopper of the twin-screw extruder, and extrude the finished PVC decorative skirting board through the twin-screw extrusion production line. The present invention has the following characteristics and advantages: the product has good toughness at low temperature, and the product has high impact resistance, high strength, heat deformation resistance, warpage resistance and low water absorption; compared with conventional heavy calcium filled products of building materials, the product has The comprehensive mechanical properties are excellent, and the cost is similar to its density; the desulfurization ash used has a good thermal stabilization effect, which can be used as a filler and a thermal stabilizer; the preparation method is simple, the material is easy to obtain, and it can produce excellent environmental and economic benefits.

Description
