Abstract

The invention discloses low-carbon environmental-friendly high-elasticity-modulus fine decoration mortar which contains the following components in parts by weight: 30-60 parts of cement, 45-80 partsof quartz sand, 1-5 parts of redispersible powder, 0.3-1 part of basalt fiber, 1-2 parts of a composite phase change material, 0.1-0.3 part of an antifoaming agent, 0.5-1 part of cellulose ether and 0.1-0.5 part of a water repellent, wherein the composite phase change material is an octadecane composite material adsorbed by silica gel; and a mass ratio of the silica gel to octadecane is (3.5-4.5):1. The invention further discloses a preparation method of the decoration mortar. The decoration mortar prepared by the invention is excellent in stability, excellent in cracking resistance, excellentin mechanical property, excellent in durability and excellent in insulating property, and the preparation conditions are mild.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a low-carbon, environment-friendly and high-elastic mold fine home decoration decorative mortar. Background technique: [0002] Generally, wall plastering mortars with a certain decorative effect are collectively called decorative mortars, which are mainly divided into interior wall plastering mortars and exterior wall plastering mortars. Exterior wall decorative mortar is greatly affected by factors such as temperature, humidity, and sunlight, and the probability of problems in engineering applications is greater, so it is more concerned in actual use. They usually consist of cement, fillers, pigments, additives and organic polymer binders. [0003] Decorative mortar is widely used as a substitute for paint and ceramic tiles, and is used as a decorative material for building exterior walls. It has a three-dimensional appearance with a natural and unique decorative effect, air permea...
