Modified nano-attapulgite clay inorganic thermal-insulation mortar coated with plant ash and preparation method thereof

Abstract

The invention discloses a modified nano-attapulgite clay inorganic thermal-insulation mortar coated with plant ash. The thermal-insulation mortar comprises the following raw materials in parts by weight: 50-60 parts of 42.5-level ordinary Portland cement, 20-30 parts of modified carbide slag, 10-20 parts of plant straw powder, 10-20 parts of nano-attapulgite clay, 40-50 parts of plant ash, 10-15 parts of starch emulsion, 2-3 parts of distearoyl isopropoxy aluminate, 10-15 parts of vitrified microspheres, 2-4 parts of redispersible latex powder, 0.5-1.5 parts of hydroxyethyl cellulose ether, 0.5-1 part of glass fiber, and 1-2 parts of polypropylene fiber. According to the invention, the produced thermal-insulation mortar is excellent in thermal insulation property and construction performance, high in intensity, good in weatherability, green and environment-friendly, and has extremely great market space and development prospect in the field of the building energy-saving application in China.

Description

technical field [0001] The invention relates to a building material, in particular to a plant ash-coated modified nano-attapulgite inorganic thermal insulation mortar and a preparation method thereof. Background technique [0002] With the popularization of building energy conservation and the continuous improvement of people's demand for the comfort of living environment, the external wall insulation system has been paid more and more attention by people. The most widely used external wall insulation system in my country's energy-saving building market is mainly composed of interface mortar, thermal insulation mortar, crack-resistant plastering mortar, alkali-resistant glass fiber mesh cloth, flexible and resistant putty and coatings. At present, thermal insulation mortars have common problems such as large capacity, large thermal conductivity, and easy cracking and hollowing, which affect the overall appearance and thermal insulation effect. , poor impact resistance and o...
