Abstract

The invention discloses a novel plastering mortar, comprising the following components by weight percent: 40% of cement, 45% of yellow sand, 5% of heavy calcium carbonate, 3.3% of talcum powder, 0.5%of lignocellulose, 0.2% of polypropylene fiber and 6% of master batch. The master batch comprises the following components by weight percent: 1.67%-8.33% of polymaleic anhydride, 5.83%-9.17% of hydroxypropyl methyl cellulose ether, 6.67%-10% of polyvinyl alcohol, 66.67%-86.67% of limestone and 0.42-0.83% of starch ether. The novel plastering mortar has advantages of excellent comprehensive adhesive ability, less excitant odor, fewer volatile organic compounds (VOC) and the like, reaches and exceeds a performance index of the plastering mortar in the standard JG158-2004, thereby promoting the development of producing energy-saving building materials, improving the level of saving energy and protecting environment and achieving good economical benefits and social benefits.

Description

technical field [0001] The invention relates to a novel plastering mortar, which belongs to the technical field of building materials. Background technique [0002] With the continuous and steady growth of my country's economic aggregate, the contradiction between energy supply and demand has become increasingly prominent, which has become a bottleneck restricting the sustainable and healthy development of my country's economy. After the reform and opening up, the rapid development of the construction industry has become the pillar industry of my country's economic development. With the increase of the completed area of ​​residential buildings, it will inevitably lead to the increase of building energy consumption. my country's annual urban and rural new housing construction area is nearly 2 billion square meters, of which more than 80% are high-energy buildings, and the existing buildings are nearly 40 billion square meters, and more than 95% are high-energy buildings.
