Embodiment 1

[0023] S101: cutting the EPS material every 500mm.

[0024] To prepare anti-cracking mortar, mix 400 parts of 42.5R ordinary Portland cement, 700 parts of river sand, 8 parts of industrial gelatin, 3 parts of wood fiber, 0.5 parts of German BASF superplasticizer (model F10), 1.5 parts of methyl hydroxypropyl cellulose, 10 parts of redispersible latex powder. The mass ratio of Deutsche Mark 5010, 8031H and 5044 in the redispersible latex powder is 3:1:6.

[0025] S102: Add water with a mass ratio of 0.4 to cement, and stir evenly.

[0026] S103: Making a grid cloth, arranging alkali-resistant glass fibers vertically and horizontally on the EPS material to make a grid cloth with a grid spacing of 10 mm.

[0027] S104: forming by machine, pouring cement mortar on the grid cloth, the pouring thickness is 5mm.

[0028] S105: Natural conservation, after 42 days of natural conservation, inspection and storage.

Embodiment 2

The mass ratio of Deutsche Mark 5010, 8031H and 5044 in the redispersible latex powder is 3:1:6.

[0032] S202: Add water with a mass ratio of 0.3 to cement, and stir evenly.

[0033] S203: making a mesh cloth, arranging alkali-resistant glass fibers vertically and horizontally on the EPS material to make a mesh cloth with a mesh spacing of 12 mm.

[0034] S204: forming by machine, pouring cement mortar on the grid cloth, the pouring thickness is 2mm.

[0035] S205: Natural conservation, after 45 days of natural conservation, inspection and storage.

Embodiment 3

Abstract

The invention provides anti-crack mortar. The anti-crack mortar consists of silicate cement, river sand, industrial gelatin, wood fibers, a water reducer, methyl hydroxypropyl cellulose and re-dispersible latex powder. The anti-crack mortar, an external wall decoration component with the anti-crack mortar and a preparation process of the external wall decoration component with the anti-crack mortar have the characteristics that the anti-crack mortar on a surface layer is resistant to impact and unlikely to break and fall off, the surface is smooth and no clearance exists in the middle; and the impact resistance of the external wall decoration component is higher than 5J, and the tensile property is over 0.1MPa.

Description

technical field [0001] The invention relates to a building component with high strength and good heat resistance, in particular to an anti-crack mortar and an exterior wall decoration component made of the anti-crack mortar. Background technique [0002] Polystyrene foam (Expanded Polystyrene referred to as EPS) is a light polymer. It uses polystyrene resin to add foaming agent, while heating to soften, generate gas, and form a foam plastic with a rigid closed-cell structure. Its processing method can be divided into pattern method and extrusion method according to the different foaming methods. This uniform and closed cavity structure makes EPS have the characteristics of low water absorption, good heat preservation, light weight and high mechanical strength. In the prior art, EPS is often used as a base material for building exterior wall decoration components to achieve weight reduction, strength improvement and thermal insulation effect. Specifically, a layer of adhes...
