Embodiment 1

[0032]The production process of the lightweight environment-friendly leveling putty using construction waste stone powder of the present invention is as follows:

[0033] According to the weight shown in Example 1 in Table 1, white cement, slaked lime, light aggregate, waste stone powder and antibacterial and anti-mildew composite auxiliary agent are taken, and these components are mixed, and evenly stirred by a machine, to obtain the use building of this embodiment. Lightweight and environmentally friendly leveling putty made of waste stone powder, packed in paper bags or in bulk.

[0034] Take 100 kg of the above-mentioned lightweight environmental protection leveling putty, add 30 kg of water to dilute, stir mechanically or manually until the mixture is uniform, and reach the viscosity (empirical viscosity) suitable for mechanical spraying or manual construction, then mechanized spraying can be carried out.

[0035] Perform performance testing according to national standard...

Embodiment 2

[0037] Get each component according to each component weight in embodiment 2 shown in table 1, and repeat the production process described in embodiment 1 (only each component weight changes) to obtain light-weight environmental protection leveling putty; Repeat embodiment 1 described The construction method, dilution weight ratio is putty: water=100: 35, and carry out performance test according to the standard described in embodiment 1, test result is as shown in the corresponding data of embodiment 2 in table two.

Embodiment 3

[0039] Get each component according to each component weight in embodiment 3 shown in table 1, and repeat the production process described in embodiment 1 (only each component weight changes) to obtain light-weight environmental protection leveling putty; Repeat embodiment 1 described The construction method, dilution weight ratio is putty: water=100: 40, and carry out performance test according to the standard described in embodiment 1, test result is as shown in the corresponding data of embodiment 3 in table 2.

Abstract

The invention discloses light and environment-friendly leveling putty, which is prepared by mixing the following components in part by weight: 20 to 25 parts of cement, 3 to 5 parts of hydrated lime, 10 to 15 parts of light aggregate, 60 to 65 parts of waste stone powder of fineness of 25 to 100 meshes and 1 part of antibacterial and mildewproof composite assistant, wherein the light aggregate is inorganic vitreous hollow microporous material of which the fineness is lower than 100 meshes; and each kilogram of the antibacterial and mildewproof composite assistant is prepared by mixing 0.4 kilogram of antibacterial and mildewproof component, 0.1 kilogram of water-retaining agent, 0.3 kilogram of redispersible polymer powder and 0.2 kilogram of air entraining agent. The waste stone powder made of building waste can be recycled, so the comprehensive utilization of building waste can be promoted and the economic, ecological and social benefit can be improved. The putty is light and improved in cracking resistance; being well compatible with a basic layer, the putty makes the leveling easy and can improve the construction efficiency and construction effect; and the putty is more suitable for molded and mechanical construction and can make the construction process simple and reduce construction price per unit square meter. The light and environment-friendly leveling putty also has the functions of reducing growth of mould and bacteria and is suitable for all indoor decorative surface leveling and polishing projects.

Description

technical field [0001] The invention relates to a building material, in particular to a lightweight environment-friendly leveling putty. Background technique [0002] At present, my country's rapid urbanization process has not only brought high-rise buildings to the city, but also brought hundreds of millions of construction waste. Construction waste refers to the dregs, spoils, waste materials, residual mud and other wastes generated during the construction, laying or demolition, and repair of various buildings and structures by construction units or individuals. According to estimates, new buildings generate about 500-600 tons of construction waste per 10,000 square meters, and the waste generated by demolition of old buildings is even more alarming, about one ton of construction waste per square meter. Since the cost of abiding by the law is far greater than the cost of breaking the law, the legal and arbitrary disposal of construction waste has become a common phenomeno...
