Embodiment

[0021] Embodiment: The polymer dry-mixed mortar of the present invention is a single-component dry powder mixed in advance and packaged in a fixed amount, for example, it can be packaged into a 25kg / bag. Powder during construction: water = 1:0.23 (weight ratio)

[0022] The weight ratio is as follows: Component Example 1 Example 2 Example 3 Example 4 Quartz sand: 65% 60% 60% 60% cement 20% 25% 23% 20% limestone powder: 8.85% 8% 9% 12% Starch Ether 3% 3% 3% 3.5% Bentonite Thixotropic Lubricant 1% 1.25% 2% 2% Silicone 1.5% 2.0% 2% 1.5% Hydrophobic Agent 0.15% 0.15% 0.2% 0.2% Methylcellulose 0.2% 0.2 % 0.3% 0.2% Cellulose Fiber 0.3% 0.4% 0.5% 0.6%

Abstract

The dry mixed polymer mortar consists of quartzite 60-65 wt%, cement 20-25 wt%, limestone powder 8-12 wt%, amylase 3-3.5 wt%, thixotropic bentonite lubricant 1-3 wt%, organic silicon compound 1.5-2.0wt%, hydrophobic agent 0.15-0.20 wt%, methyl cellulose 0.20-0.30 wt% and cellulose fiber 0.30-0.60 wt%. It is one kind of green furnishing and decorating material and has the features of light weight, high strength, high adhesion, being fireproof, etc.

Description

technical field [0001] The invention relates to a building plastering mortar, in particular to a polymer mortar. Background technique [0002] The existing polymer mortar contains toxic and harmful substances, and is made of cement plus acrylate or aldehyde organic substances. It is easy to crack after plastering, and has adhesion, waterproof and air permeability, impact resistance, toughness, and workability. , The disadvantage of poor weather resistance. The existing polymer mortar is made by the construction unit purchasing the raw materials separately, unpacking, weighing, mixing and mixing the separately packaged raw materials at the construction site. Due to various uncertain factors on the construction site If there are too many, workers will inevitably have inaccurate measurement problems, which will affect the construction quality. Contents of the invention [0003] The purpose of the present invention is to provide a polymer dry-mixed mortar to solve the proble...
