Embodiment 1

[0020] A modified powder capable of improving the stability of polymer cement waterproof coatings, which is made of the following components in mass percentage: nano-silicon carbide 5%, kaolin powder 5%, nano-boron carbide 5%, fly ash 5%, 0.02% micron alumina, 0.01% graphene, 0.2% modified starch, 0.3% potassium carbonate, 0.05% rare earth light-changing agent, and the balance is nano-silica;

[0021] The preparation method is as follows:

[0022] 1) Mix the above materials evenly, bake in a baking equipment at a temperature of 86-95°C for 30-40 minutes, then quickly cool to room temperature, crush through a 60-mesh sieve, and obtain a mixed powder for use;

[0023] 2) Use absolute ethanol as the dispersion medium for the mixed powder, wherein the mass ratio of the mixed powder to absolute ethanol is 1:30, and ultrasonically disperse on an ultrasonic cleaning machine for 1 hour;

[0024] 3) Put the ultrasonically dispersed mixed powder into a nylon ball mill tank, use agate b...

Abstract

A modified powder capable of raising stability of a polymer-cement waterproof coating is characterized by being prepared from the following ingredients (by weight): 5% of nano-silicon carbide, 5% of kaolin powder, 5% of nano-boron carbide, 5% of fly ash, 0.02% of micro-alumina, 0.01% of graphene, 0.2% of modified starch, 0.3% of potassium carbonate, 0.05% of a rare-earth light conversion agent and the rest of nano-silica. As the powder of the polymer-cement waterproof coating is specially prepared and modified, the prepared polymer-cement waterproof coating has good stability, large elongation, high bonding strength and good water resistance, alkali resistance and weather fastness, can be directly constructed on a water-free base surface, and is widely applied in waterproofing of low-activity bases of kitchens, rest rooms, balconies, basements and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a modified powder capable of improving the stability of polymer cement waterproof coatings. Background technique [0002] At present, the bonding interface of some building components used in the construction field at home and abroad often has surface cracking, falling off, and even damage to the component body due to the influence of various factors, resulting in doubled building safety hazards. The specific manifestations are as follows: 1. In the external wall thermal insulation project and its decoration project, the pasted thermal insulation board and decorative board (brick) often appear to fall off from the external wall of the building; 2. The wall cement plastering of the building envelope Surface cracking, hollowing, and cracking will occur in the layer, thermal insulation leveling layer, finishing layer, roof concrete waterproof layer, etc.; , caulking materials, cau...
