Embodiment 1

[0099] With respect to 100 parts by weight of the crosslinkable silyl group-containing polymer (manufactured by Kaneka Co., Ltd., Kaneka MS Polymer S303H) (recorded as MS in Table 1) as the component (A), it was measured as a plasticizer agent, that is, 50 parts by weight of polypropylene glycol with a number average molecular weight of 3000, 160 parts by weight of colloidal calcium carbonate, 54 parts by weight of ground calcium carbonate, 20 parts by weight of titanium oxide as a white pigment, 2 parts by weight of a thixotropy imparting agent, and The mixture was mixed in a planetary mixer, and vacuum dehydration was performed at 120° C. for 2 hours. After cooling to below 50°C, 3 parts by weight of vinyltrimethoxysilane as a dehydrating agent and 3 parts by weight of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane as an adhesion-imparting agent were mixed. parts by weight, 2 parts by weight of a tin-based curing catalyst, and kneaded in a state substantially free of moistur...

Embodiment 2

[0104] The composition of Example 1 was applied in the gap of the mortar wall material at a position 2 mm lower than the surface, and the remaining procedures were the same as in Example 1. As in Example 1, the thickness of the water-based paint, the fracture under tensile stress, and the color change of the coating film were observed, and they were maintained as in Example 1. The results are shown in Table 1.

Embodiment 3

[0106] In the composition of Example 1, a crosslinkable silyl group-containing polymer (crosslinkable silyl group-containing polyurethane-based polymer, described as ISPU in Table 1) was used as the component (A), and the rest Procedure is identical with embodiment 2. In addition, as in Example 2, the thickness of the water-based paint, the fracture under tensile stress, and the color change of the coating film were observed, and all remained good. The results are shown in Table 1.

Abstract

The invention relates to an indoor wall surface structure and a manufacturing method thereof. The indoor wall surface structure comprises a plurality of wall materials, connectors and coating films, wherein the connectors are used for sealing and connecting the adjacent wall materials, and the upper surfaces of the wall materials and the connectors are coated with the coating films. The connectorscomprise lower filling layers and upper filling layers, and the lower filling layers are cured products of sealing materials containing polymers with cross-linked silyl. The upper filling layers arelocated on the lower filling layers, and the upper surfaces of the upper filling layers and the upper surfaces of the wall materials are located in the same plane. The wall materials and the upper filling layers are each of a porous structure. According to the indoor wall surface structure, the whole wall can be provided with the plane without pits.

Description

technical field [0001] The present invention relates to an indoor wall surface structure and a method of manufacturing the indoor wall surface, especially a method of filling the joints of the indoor wall surface with a sealing material containing a polymer containing a cross-linkable silyl group and then applying a paint, And how to maintain the beauty of the wall. Background technique [0002] In the final treatment of the interior walls of the living space, the following method is adopted: After the wall panels (wall materials) are vertically installed, the gap between the wall panels is filled with a filler material formed by dispersing inorganic substances in water, Afterwards, a water-based adhesive mixed with talcum powder is applied to the entire wall, and after the material is cured, the entire surface is polished and then painted. Although the final treatment effect of this method is beautiful, there are many processes, and the labor and time of the operator are s...
