Problems solved by technology

However, composite Portland cement is added to its composition, and the silicate is a weak acid and strong alkali salt, which undergoes a hydration reaction with water to form free calcium, silicic acid and hydroxide, which leads to the fact that the cement is often exposed to rainwater. The parts are prone to efflorescence, affecting the appearance of the building and causing quality problems

Abstract

The invention discloses multifunctional paste-shaped plaster and a preparation method thereof. The multifunctional paste-shaped plaster is prepared from 30-45 parts of quartz sand, 25-35 parts of packing, 0.2-0.5 part of water retention thickening agent, 20-40 parts of emulsifying agent, 0.5-1 part of coalescing agent, 0.1-0.15 part of preservative, 0.2-0.3 part of defoaming agent and 1-2 parts of anti-cracking fibers. The preparation method includes the steps that the quartz sand, the packing, the water retention thickening agent and the wood fibers are weighed first, and then are evenly stirred after being mixed, so that a mixed material is obtained; afterwards, a certain quantity of silicone-acrylic emulsifying agent is weighed and added into a stirring machine to be stirred, the defoaming agent, the coalescing agent and the preservative are added while stirring is carried out, and the mixture is fully and evenly mixed; then the mixed material which is well mixed before is added to be fully mixed and evenly stirred. The plaster does not contain cement, and thus the efflorescence condition can be avoided when solidified plaster meets rainwater.

Description

technical field [0001] The invention relates to the field of construction, and more specifically relates to a multifunctional paste-like cement and a preparation method thereof. Background technique [0002] Clay is a muddy plastic solid with strong adhesive properties. This type of plastic solid is generally composed of solid or liquid adhesives with adhesive properties and powder fillers with certain functions. Appropriate pigments and Accessories. [0003] The Chinese patent application number is 201210453312.9, which discloses a polymer cement, which is a single-component, dry powder, water-based, processed through scientific proportioning, and integrates waterproof, bonding, plugging and leveling functions. An integrated non-toxic and tasteless water-based self-leveling cement-based rigid-flexible waterproof paste plugging and leveling material, which belongs to cement-based polymer water-based dry powder waterproof mortar. However, composite Portland cement is added ...
