Embodiment 1

[0046] A new formula for improving the Vicat softening temperature of PVC building formwork, which is made of the following ingredients in parts by weight: 75 parts of type 5 PVC resin, 65 parts of plastic steel powder, 25 parts of light calcium powder, 2.39 parts of stabilizer, CPVC resin 12.5 parts, 9 parts of basalt glass fiber, 4 parts of processing aid, 0.9 part of white foam, 0.4 part of yellow foam, 6.5 parts of foam regulator, 0.56 part of internal lubrication, 0.75 part of external lubrication, and 0.15 part of high temperature lubrication. The stabilizer is a composite lead salt stabilizer. The basalt glass fiber is formed by melting basalt rock at 1488°C and then drawing it with a platinum-rhodium alloy drawing bushing. The white foam is sodium bicarbonate. The yellow foam is azodicarbonamide. The foaming regulator is an acrylic foaming regulator; the processing aid is an acrylic processing aid. The internal lubrication is zinc stearate; the external lubrication ...

Abstract

The invention discloses a novel formula for improving the vicat softening temperature of a PVC building template, relates to the technical field of building templates, and is prepared from the following components: 5-type PVC resin, plastic steel powder, light calcium powder, a stabilizer, CPVC resin, basalt glass fibers, a processing aid, white foam, yellow foam, a foam regulator, an inner lubricant, an outer lubricant and a high-temperature lubricant. According to the novel formula for increasing the Vicat softening temperature of the PVC building template, the mechanical property of the PVC building template is greatly improved by optimizing the formula components and the dosage of each component, and particularly the tensile property is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building templates, in particular to a new formula for increasing the Vicat softening temperature of PVC building templates. Background technique [0002] In the current building construction, the process of using wood-glued formwork and wooden squares is very common. The average turnover times of wood-glued formwork is 3 to 8 times, and the turnover times of wooden squares is 1 to 2 floors. It cannot be recycled after use. For this reason, the Ministry of Housing and Urban-Rural Development vigorously advocates the promotion of building formwork to replace wood with "plastic", so various new building plastic formworks have emerged as the times require. There are roughly two types of plastic materials, the first is PP polypropylene material, and the second is PVC polyvinyl chloride material. Due to the high cost of PP polypropylene materials, it is difficult to promote them in large quantities. Althoug...
