Abstract

A mortar base material comprises the following raw materials: cement, quartz sand, waterproofing agent, 0.1-0.15 parts of defoaming agent, water, hydroxyethyl cellulose, double fly powder, styrene-acrylic emulsion, bactericide and anti-mold agent. A method for preparing a mortar base material is also proposed, comprising the following steps: after dry mixing cement, quartz sand, hydroxyethyl cellulose and Shuangfei powder, adding water for stirring and mixing; obtaining mixture a; mixing waterproofing agent, defoaming agent Add the agent, styrene-acrylic emulsion, bactericide and anti-fungal agent to the water in order to stir and mix; obtain the mixture b; add the mixture b to the mixture a and stir to obtain the slurry; pour the slurry into the test mold and scrape it flat, put Curing with the mold in the curing box, take out the test mold and remove the mold to obtain the test piece; put the test piece in saturated lime water for curing, take it out and rinse it with water, dry it, and then cool it to room temperature to get the mortar base material. The invention is easy to form, low in cost, and low in shrinkage rate and water absorption rate, so that the wall surface is dry and not easy to be damp and moldy.

Description

technical field [0001] The invention relates to the field of mortar base materials, in particular to a mortar base material and a manufacturing method thereof. Background technique [0002] Waterproof coating film is a building waterproof material made of cement and fine aggregate as the main component, polymer emulsion or redispersible latex powder as modifier, and an appropriate amount of additives. It has a certain degree of extensibility, waterproofness, and strong bonding ability with the base surface. It is widely used in exterior walls, roofs, basements and toilets, etc. where waterproofing is required. When tiny cracks occur in the base mortar or concrete, the waterproof coating film applied on it should have a certain ability to fill the cracks, so as to resist the failure of the waterproof function caused by the spread of cracks. However, in the preparation process of the existing mortar base material, there are high production costs, complicated preparation proce...
