Problems solved by technology

[0005] However, the present invention believes that these existing decorative lines still have problems such as lack of thermal insulation performance, or are bulky, difficult to install, low in strength, and poor in weather resistance. Therefore, it is necessary to further develop EPS molding lines. The application of EPS modeling lines is of great significance

Abstract

The invention belongs to the technical field of exterior wall molding moldings, and in particular relates to EPS molding moldings and a preparation method. The EPS molding lines include: 250-380 parts of cement; 660-775 parts of quartz sand; 18-26 parts of rubber powder; 1.1-2.4 parts of hydroxypropyl methylcellulose; 1.5-3.5 parts of wood fiber; 1.5 parts; 1‑3 parts of water reducer; 1‑4 parts of thickener; 3‑8 parts of calcium formate. The EPS molding line of the present invention is mainly bonded to the wall surface with polymer mortar, has a long service life, is firmly bonded, and avoids hidden dangers of anchor bolt fixing method construction and anchor bolt corrosion.

Description

technical field [0001] The invention belongs to the technical field of exterior wall molding moldings, and in particular relates to EPS molding moldings and a preparation method. Background technique [0002] EPS decorative line is a new type of exterior wall decorative line and component, which has the advantages of convenient installation and economy. At present, the traditional exterior wall decoration lines mainly include concrete cast-in-place lines, 4C prefabricated lines, and gypsum lines; for example, patent document 201711175140.2 discloses a gypsum line and its preparation method, which is made of the following materials in parts by weight: gypsum powder 25-30 parts, 30-35 parts of clear water, 4-8 parts of starch, 8-13 parts of glue, 13-18 parts of white cement, 1-4 parts of hydroxypropyl methylcellulose ether, 2-5 parts of acrylic acid solution, 1-3 parts of calcium stearate, 1-2 parts of sodium benzoate, 8-13 parts of expansion agent, 7-11 parts of auxiliary ag...
