Abstract

The invention discloses plastering mortar for the exterior wall external insulation of a phenolic aldehyde foam board, and a preparation method thereof. The plastering mortar for the exterior wall external insulation of the phenolic aldehyde foam board is prepared from the following components in parts by weight: 350 to 450 parts of sulphate aluminum cement, 500 to 600 parts of quartz sand, 50 to100 parts of zeolite powder, 4 to 6 parts of cellulose ether, 25 to 30 parts of rubber powder, 15 to 20 parts of bentonite, and 2 to 3 parts of short fiber. The plastering mortar provided by the invention is simple in formula and reasonable in matching ratio; the synergism of the components is good, so that the activity and the workability are improved; the plastering mortar is easy to float in site by workers, so that the operability is high. The mortar contains a certain amount of active silica and disilicon trioxide which can be acted with hydration product calcium hydroxide of the cement so as to generate a low-alkaline condensate with a stable property, and a gel material is formed, so that the strength is improved. The alkalinity of the cement is slowly neutralized, so that a pH value in the plastering mortar is reduced; during the application process, the mortar contact an acid phenolic aldehyde board so as to obtain better strength, so that the risk of cracking and falling between the mortar and the phenolic aldehyde board can be reduced, and the better safe connectivity is obtained.

Description

technical field [0001] The invention relates to the field of plastering mortar materials, in particular to a plastering mortar for external thermal insulation of external walls of phenolic foam boards and a preparation method thereof. Background technique [0002] The current urban construction attaches great importance to the energy-saving design of buildings, and the country has invested a lot of money in the construction of energy-saving and thermal insulation for the outer walls of old residential areas in urban areas. Phenolic foam inherits the flame retardancy and structural stability of phenolic resin itself. It has the characteristics of fire resistance and flame retardancy, no dripping in case of fire, good dimensional stability in alternating hot and cold environments, and acid and alkali corrosion resistance. It has achieved great achievements in the field of building energy conservation. Great development. [0003] The construction of external wall insulation te...
