Abstract

The invention belongs to the field of building materials, and particularly relates to an efflorescence-free heat-insulating and energy-saving wall board and a preparation method. The efflorescence-free heat-insulating and energy-saving wall board comprises the following raw materials in percentage by total weight: 73-76% of vitrified microbeads, 18-30% of a water-soluble adhesive and 3-5% of a hydrophobic agent. The preparation method comprises the following steps: A, adding the vitrified microbeads, the water-soluble adhesive and the hydrophobic agent into a stirrer, and uniformly mixing to obtain a mixture; B, adding the mixture obtained in the step A into a mould, and performing compression moulding by using a hydraulic press to obtain a board; and C, curing the board obtained in the step B through microwave drying to obtain the heat-insulating and energy-saving board. Compared with the conventional product, the heat-insulating and energy-saving board provided by the invention has the advantage of capability of effectively solving a wall efflorescence phenomenon; moreover, the heat-insulating and energy-saving wall board has fire-proof and heat-insulating functions; and the preparation method is simple.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermal insulation and energy-saving board for a non-efflorescent wall surface and a preparation method thereof. Background technique [0002] In the modern construction industry, the walls of buildings are prone to pan-alkali over time. Pan-alkali refers to the silicate concrete used in general home buildings or engineering buildings. After a period of time, the walls will appear Salt-like crystals. The rough room will be directly precipitated, and the decorated ones, paints, etc. will bulge, peel, and fall off. It does not fade for many years and seriously affects the appearance. This phenomenon is called "pan-alkali". Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a thermal insulation and energy-saving board that can effectively solve the phenomenon of efflorescence on the wall surface, and a...
