Embodiment Construction

[0007] Prepare raw materials according to the technical scheme of the present invention, and configure raw materials by the following percentages: polyvinyl butyral 70%, iron oxide red 10%, aluminum hydroxide 4%, calcium carbonate 4%, talcum powder 4%, laterite 4%, quartz sand 4%.

[0008] Slice polyvinyl butyral and put it into an internal mixer, heat up to melt. Add calcium carbonate, talcum powder, aluminum hydroxide, red iron oxide, laterite, and quartz sand in sequence, and stir to mix evenly. Cool down and extrude through an extruder.

[0009] Among them, the main raw material polyvinyl butyral elastomer is the basic waterproof adhesive material. Because a large amount of polyvinyl butyral leftovers are mixed in color, the present invention introduces iron oxide red to make the waterproof material uniform in color. In order to make the waterproof material have excellent fireproof performance, the present invention uses high-quality and low-cost aluminum hydroxide as a...

Abstract

This invention relates to a waterproof material for construction, especially poly (vinyl butyral) waterproof material. The waterproof material is composed of: poly(vinyl butyral) 60-80 wt.%, Fe2O3 8-10 wt.%, Al(OH)3 3-5 wt.%, CaCO3 3-5 wt.%, talcum powder 3-5 wt.%, laterite 3-5 wt.%, and quartz sand 3-5 wt.%. The product has such advantages as good waterproof property and low price. Part of the raw materials are recovered wastes, thus this invention is environmentally friendly.

Description

technical field [0001] The invention relates to a waterproof material for construction engineering, in particular to a waterproof material formed by polyvinyl butyral, which belongs to the technical field of waterproof materials for construction engineering. Background technique [0002] At present, most of the existing general-purpose waterproofing materials for buildings are SBS waterproofing membranes, random-grade propylene waterproofing membranes and EPDM waterproofing membranes. The production cost and sales price of the above-mentioned waterproof materials are generally high. As the international crude oil price continues to rise, this disadvantage becomes more and more obvious. Chinese Invention Patent Publication No. 1472266A discloses "A Polyvinyl Butyral Anti-acid and Alkali Erosion Resistance Paint", Chinese Invention Patent Publication No. 1422930A discloses "A New Waterproofing Agent", the technical solutions disclosed in the above two ...
