Problems solved by technology

The construction of tile roofs is inseparable from cement-bonded mortar. In actual construction, most of the mortar is mixed with cement and sand on site, and the quality of mortar is unstable. Secondly, ordinary cement mortar is rigidly bonded, has poor flexibility and It is easy to produce hollowing and cracks, which will lead to cracking and water seepage of the mortar bonding layer; in addition, the traditional tile roof bonding mortar does not have the function of heat preservation

Abstract

The invention discloses tile type roof waterproof heat-insulating binding mortar. The tile type roof waterproof heat-insulating binding mortar consists of a powder material component and a liquid material component in the mass ratio of 1:0.8; the powder material component comprises the following components in parts by mass: 1 to 50 parts of cement, 20 to 80 parts of sand, 0.5 to 2 parts of dispersible latex powder, 0.5 to 5 parts of cellulose ether, 0.1 to 5 parts of a waterproof agent, 1 to 20 parts of glass fibres and 10 to 30 parts of glass micro-beads; the liquid material component is acrylate emulsion. The invention also discloses a preparation method of the mortar. The tile type roof waterproof heat-insulating binding mortar disclosed by the invention can be widely applied to construction of a characteristic town tile type roof and a common tile type roof, has water resistance, heat insulating property, toughness, crack resistance and durability that common cement mortar does nothave, and is convenient to construct.

Description

technical field [0001] The invention relates to the technical field of mortar, in particular to waterproof and thermal insulation bonding mortar suitable for tile roofs. Background technique [0002] In July 2016, the Ministry of Housing and Urban-Rural Development, the National Development and Reform Commission, and the Ministry of Finance jointly issued the "Notice on Carrying out the Cultivation of Characteristic Towns" and proposed that by 2020, about 1,000 characteristic towns should be cultivated. Most of the current construction of characteristic towns adopts the design concept of retro tile roofs. The construction of tile roofs is inseparable from cement-bonded mortar. In actual construction, most of the mortar is mixed with cement and sand on site, and the quality of mortar is unstable. Secondly, ordinary cement mortar is rigidly bonded, has poor flexibility and It is easy to produce hollowing and cracks, which will lead to cracking and water seepage of the mortar ...
