Shale heat-preserving heat-insulating wall putty

Abstract

According to the element analysis of shale mine, shale has such fine physical and chemical performances as high strength, heat insulation, thermal retardation, sound absorption, fire resistance, resistance to water, corrosion attack, antiknock, frost resisting, strong absorbability and on the like. On this basis, a thermal retardation and heat insulation wall lacquer putty which is well matched with the wall paint is prepared with shale powder being the filler instead of the filler of the general wall lacquer putty. The shale raw materials are abundant in source, low in processing cost and simple in synthesis operation. The shale thermal retardation and heat insulation wall lacquer putty is characterized by high bond strength, excellent cracking resistance, strong weather resistance, thermal retardation, heat insulation and the like. The invention extends the application field of the shale mine.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a shale heat-insulating wall putty which can be applied to the fields of industrial building materials and the like. Background technique [0002] Construction putty is a wall material that has developed rapidly in recent years. Its predecessor is the mortar applied on the wall, which is composed of cement, lime paste and sand or gravel, mixed with water to form mortar or gravel slurry, and then applied to the wall to make the wall smooth. The wall finish is easy to crack, fall off, discolor and has poor durability, so it cannot be painted. With the rapid development of my country's construction industry, the quality of wall decoration is getting higher and higher, and construction putty instead of mortar has gradually developed. At present, there are many kinds of construction putty, and the quality is uneven. The most common one is the putty made of 107 glue, cem...

AI Technical Summary

Problems solved by technology

However, the bonding strength provided by the gelling property of cement hydration products is not enough, and the thermal stability of cement hydration products is poor, easy to dry shrinkage, deformation, cracking, high brittleness, poor durability, and the flatness of scraping coating cannot meet the requirements, so it is necessary Modification of these traditional construction putties to improve their performance

[0004] The current interior wall latex paint products range from flat to glossy, and the sales price ranges from 5 to 40 yuan / kg. It is obviously inappropriate to use the same putty as the bottom treatment material for paints with such a large quality difference

At present, the putty on the market may not have a logo for high-grade paint coating or ordinary paint coating, but only for interior wall or exterior wall paint coating.
