Preparation method of polymer quick-drying early-strength corrosion-resistant mortar

Abstract

The invention relates to the technical field of mortar manufacturing and application, and discloses a manufacturing method of polymer quick-drying early-strength anti-corrosion mortar. The method comprises the following raw materials: 160-180 parts of sulphoaluminate cement, 50-60 parts of calcined gypsum powder, 80-90 parts of Portland cement, 0.5-1 part of a polycarboxylate superplasticizer, 3-6 parts of a rheological additive, 5-10 parts of hydroxyethyl methyl cellulose ether and an acrylic polymer. According to the manufacturing method of the polymer quick-drying early-strength corrosion-resistant mortar, the acrylic polymer is added into the quick-drying early-strength corrosion-resistant mortar according to the mixing ratio of 4: 1, and compared with a common mortar layer, besides quick drying and early strength, internal gaps are obviously filled due to the addition of the special acrylic polymer, the mortar is high in impermeability and breaking strength, so that the problems of poor impermeability and low breaking strength of a mortar layer due to more gaps during construction of the existing mortar are effectively solved.

Description

technical field [0001] The invention relates to the technical field of mortar production and application, in particular to a production method of polymer quick-drying early-strength anti-corrosion mortar. Background technique [0002] Mortar is a bonding substance used in building bricks. It is made of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) Mortar), lime mortar and clay mortar. Mortar is used for masonry and plastering projects, and can be divided into masonry mortar and plastering mortar. The former is used for masonry and component installation of bricks, stones and blocks, while the latter is It is used for plastering on walls, floors, roofs and beam-column structures to meet protection and decoration requirements. [0003] Mortar has been widely used nowadays. With the development of economy and society, more and more places and sites have put forward requirements for corrosion resistance, such as sewage pools in sewage tre...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for making polymer quick-drying, early-strength and anti-corrosion mortar, which has the advantages of filling internal gaps and good practicability, and solves the problem of existing mortars during construction. Many gaps lead to poor impermeability and low flexural strength of the mortar layer
