Novel energy-saving and environment-friendly waterproof plastering gypsum and preparation method thereof

Abstract

The invention relates to the field of industrial waste utilization and building materials, in particular to novel energy-saving and environment-friendly waterproof plastering gypsum and a preparation method thereof. The novel waterproof plastering gypsum is prepared from the following components in percentage by weight: 45 to 60 percent of natural gypsum, 20 to 35 percent of quartz sand, 8 to 15 percent of mineral ash residue, 3 to 8 percent of calcium elevator, 1.5 to 3 percent of waterproof agent, 0.3 to 0.6 percent of gypsum water reducing agent and 1.2 to 3 percent of additive. The preparation method comprises the following steps: weighing proportioning accessories according to a formula; mixing the accessories and putting into a stirring reactor; sufficiently and uniformly stirring to obtain the waterproof plastering gypsum. The novel energy-saving and environment-friendly waterproof plastering gypsum disclosed by the invention has the beneficial effects that after a product is immersed into water for two times and then is dried, the strength is till kept unchanged; mineral waste residues are used as raw materials, so that recycling of wastes is realized, and energy-saving and environment-friendly properties are obtained; when the plastering thickness is smaller than 40mm, the novel energy-saving and environment-friendly waterproof plastering gypsum can be directly applied to a treated base layer, and is high in viscosity and free of hollowing and cracking; after use, the indoor temperature and the indoor humidity can be effectively controlled and adjusted; the novel energy-saving and environment-friendly waterproof plastering gypsum has excellent heat-insulating property, heat-insulating function and water resistance.

Description

Technical field [0001] The invention relates to the field of industrial waste utilization and building materials, in particular to a novel energy-saving, environment-friendly and waterproof plaster and a preparation method thereof. Background technique [0002] The extensive use of new energy-saving wall materials, the introduction of new wall materials using mine waste slag as raw materials. At the beginning of the implementation, wall materials made by mixing with gypsum and lime, etc., due to their strong water absorption and lack of adhesion , The wall is prone to hollowing, powder falling and other phenomena. At the same time, the existing products are stirred with water during use. After the unused plaster is solidified, if water is added again and stirred, the strength of the product itself will be lost and cannot be used, resulting in waste. Summary of the invention [0003] Combining the shortcomings of the prior art, the purpose of the present invention is to provide a n...

Problems solved by technology

[0002] With the wide utilization of new energy-saving wall materials, new wall material products using mine waste residue as raw materials have been introduced. At the beginning of implementation, wall materials made by mixing them with gypsum, lime, etc., due to their strong water absorption and lack of adhesion , The wall is prone to hollowing, powder falling, etc. At the same time, the existing products are mixed with water when they are used. If the unused plaster plaster is cured and then mixed with water again, the strength of the product itself will be lost, and it cannot be used, resulting in waste.
