Embodiment 1

[0030] A raw material for wall surface spraying, comprising the following components in parts by mass: 180g of gypsum powder, 104g of water, 20g of soft clay, 20g of silicone resin, 6g of vitrified microbeads, 5g of water reducing agent, 3g of crosslinking agent, Expanded graphite 2g. The silicone resin is any one of methyltrichlorosilane, dimethyldichlorosilane or phenyltrichlorosilane. The water reducer is any one of fatty acid-based water-reducer, naphthalene-based water-reducer or sulfamic acid-based water-reducer. The crosslinking agent is any one of dicumyl peroxide, benzoyl peroxide or di-tert-butyl peroxide.

[0031] Such as figure 1 , figure 2 and image 3 As shown, the wall surface includes a wall base layer 1, a first layer of wall surface 2 and a second layer of wall surface 6 from the inside to the outside, the first layer of wall surface 2 includes a new glass fiber cloth containing airgel, and the new The glass fiber cloth is bonded to the base layer 1 of ...

Embodiment 2

[0047] Example 2 Compared with Comparative Example 1, no soft clay was added in Comparative Example 1, and the waterproofness of the wall surface was relatively weak. Among them, the vitrified microbeads played a certain waterproof effect, but the effect was relatively limited, causing moisture to enter the wall surface Inside, so that the wall material has partially fallen off.

[0048] Embodiment 2 Compared with comparative example 2, the wall surface sprayed by comparative example 2 is wet and has poor thermal insulation. Vitrified microbeads are not added in comparative example 2, which causes the water resistance of the sprayed raw material to be greatly reduced. Simultaneously, although there is expansion in the sprayed raw material Graphite, but with limited insulating properties.

[0049] Compared with Example 2 and Comparative Example 3, the wall surface sprayed in Comparative Example 3 has obvious cracks. In comparative example 3, there are separate vitrified microb...

Abstract

The invention relates to the technical field of wall surface treatment and discloses a wall surface spraying raw material and a spraying method. The wall surface spraying raw material is prepared fromthe following components in parts by mass: 90 to 96 parts of a gypsum powder, 52 to 60 parts of water, 10 to 26 parts of soft clay, 10 to 20 parts of organic silicon resin, 3 to 6 parts of glazed hollow beads, 2 to 3 parts of a water reducing agent, 1 to 2 parts of a cross-linking agent and 1 to 2 parts of expanded graphite. The spraying method using the wall surface spraying raw material comprises the following steps: firstly, pretreatment of a fiberglass fabric; secondly, treatment of a first-layer wall surface; thirdly, treatment of a second-layer wall surface; fourthly, post treatment ofthe whole wall surface. According to the spraying method disclosed by the invention, water resistance, insulation property and crack resistance of wall surface spraying are improved.

Description

technical field [0001] The invention relates to the technical field of wall surface treatment, in particular to a wall surface spraying raw material and a spraying method. Background technique [0002] In the current construction field, the interior and exterior walls of a building are decorated to make the building beautiful and practical. At present, there are two ways to decorate the wall: coating or painting and sticking tiles and stones. The former generally has poor thermal insulation and moisture resistance, and is prone to problems such as cracking, falling off, fading, and mildew. The latter has high construction costs, long paving and pasting operation cycle, difficult to control the flatness, easy to fall off the brick body, and prone to water seepage. Therefore, a new type of wall surface treatment method has appeared now, that is, the wall surface spraying treatment method. First, the spraying raw materials are mixed, and then added to the air compressor to ca...
