Problems solved by technology

However, the conventional polymer cement waterproof mortar has low compressive strength, large shrinkage rate, poor acid and alkali resistance, and poor corrosion resistance. Moreover, the coating strength is low due to insufficient scientific formula design, which cannot guarantee the safety of the next construction. , Secondly, the price of polymer is relatively expensive, and the addition of a large amount of polymer leads to an increase in the price and cost of cement mortar

Abstract

The invention discloses cement-based polymer waterproof mortar which is characterized by being prepared from, by weight, 5-10 parts of 3-chloro-2-hydroxy propane sulfonic acid ionized modified hyperbranched polyamino acid, 2-5 parts of a fatty acid-based addition polymer, 0.5-2.5 parts of calcium borogluconate, 1-3 parts of nano alumina sol, 10-15 parts of pelelith powder, 100 parts of Portland cement, 3-7 parts of palygorskite powder, 3-5 parts of glass fiber powder, 3-8 parts of industrial solid waste powder, 20-30 parts of a styrene-acrylic emulsion, 1-3 parts of sodium laureth sulfate modified crosslinked super absorbent resin, 80-120 parts of fine sand and 80-100 parts of water. The invention also discloses a preparation method of the cement-based polymer waterproof mortar. The cement-based polymer waterproof mortar has the advantages of good impermeability, low water absorption rate, high bending strength and bonding strength, convenient construction, aging resistance and remarkable waterproof performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cement-based polymer waterproof mortar and a preparation method thereof. Background technique [0002] With the development of the economy and the acceleration of urbanization, more and more people have entered the big cities, and many small and medium-sized cities are gradually moving towards modernization. Behind the construction of these modern cities, the construction of large-scale construction projects is inseparable. Mortar is one of the most widely used construction materials in the construction process of these construction projects, and is widely used in masonry and plastering of buildings. [0003] Mortar is made by mixing inorganic gelling material, fine aggregate and water in proportion. There are a large number of capillary pores and hydrophilic hydroxyl groups inside this material, which is easy to absorb water in a humid environment and cause frost da...
