Problems solved by technology

This problem occurs because the main component of the glue used to impregnate the veneer paper and the veneer film is phenolic impregnated glue, and the phenolic impregnated glue is dark red, it is difficult to lighten it, so that the glue impregnated with such glue The color of the face paper and face mask is black or dark brown
However, the wood color of the wooden floor is light yellow, so the black and dark brown veneer paper and veneer film are pasted on the surface of the wooden floor. When the surface is damaged due to abnormal reasons during use, the veneer paper and veneer film will be damaged. The light yellow color of the bare exposed wood forms a strong color contrast and affects the appearance

Embodiment 1

[0013] In this embodiment, the impregnated phenolic glue used has a solid content of 44-48%, a pH of 9-10, and a viscosity of 23-30cp / 30°C (centipoise). Titanium dioxide contains more than 93% titanium. Iron oxide yellow is a 320 mesh powder with a purity of 98%. Oleic acid is refined industrial oleic acid, acid value: 190-220mgKOH / g saponification value: 190-220mgKOH / g. The dispersant is a common dispersant, preferably sodium methylene dinaphthalene sulfonate. The toughening agent is polyvinyl acetate emulsion.

[0014] Such as figure 1 As shown, impregnate 100 parts of phenolic glue, 20 parts of titanium dioxide, 1.2 parts of oleic acid, 1.5 parts of iron oxide yellow, 0.2 parts of dispersant, and 0.3 parts of toughening agent. Stir and mix the above materials for 25 minutes to obtain light yellow liquid viscous glue , and then impregnated with non-woven fabric in the above glue, squeezed by double rubber rollers, dried to remove 35% of the water to a semi-dry state, and...

The dispersant is a common dispersant, preferably sodium methylene dinaphthalene sulfonate. The toughening agent is polyvinyl acetate emulsion.

[0017] Such as figure 1 As shown, impregnate 100 parts of phenolic glue, 15 parts of titanium dioxide, 1.4 parts of oleic acid, 1.5 parts of iron oxide yellow, 0.3 parts of dispersant, and 0.3 parts of toughening agent. Stir and mix the above materials for 30 minutes to obtain light yellow liquid viscous glue , and then impregnated with non-woven fabric in the above glue, squeezed by double rubber rollers, dried to remove more than 35% of the water, and then to a...

Embodiment 3

[0019] In this embodiment, the dispersant used is a common dispersant, preferably sodium methylene dinaphthalenesulfonate. The toughening agent is polyvinyl acetate emulsion.

[0020] Such as figure 1 As shown, impregnate 80 parts of phenolic glue, 20 parts of titanium dioxide, 1.0 part of oleic acid, 1 part of iron oxide yellow, 0.1 part of dispersant, and 0.2 part of toughening agent. Stir and mix the above materials for 20 minutes to obtain light yellow liquid viscous glue , and then use non-woven fabrics to soak in the above glue, squeeze through double rubber rollers, dry to remove 35% of the water, and then stick to the container wooden floor to get the same light yellow surface effect as wood.

Abstract

The present invention aims to provide a kind of glue formula for impregnating veneer paper and veneer film and the method that this glue is used for wood floor film, the color of the veneer paper and veneer film impregnated with this glue is light yellow, and the color of wood similar or identical. In order to achieve the above object, the glue of the present invention includes the following components by weight fraction: 80-120 parts of impregnated phenolic glue, 15-25 parts of titanium dioxide, 0.7-1.4 parts of oleic acid, 1-2 parts of iron oxide yellow, dispersed Agent 0.1-0.3 parts, toughening agent 0.2-0.5 parts. The invention solves the problem of color transformation of red phenolic aldehyde impregnated glue, and makes the color of the veneer film similar to or consistent with the color of the wood itself, which not only protects the wood on the surface of the wooden floor, but also improves the appearance of the surface, avoiding the appearance of the wooden floor. Due to abnormal damage, the color contrast is too large to affect the appearance.

Description

technical field [0001] The invention relates to a glue used for impregnating a container floor veneer film and a construction method thereof. Background technique [0002] In the past, the veneer paper and veneer film pasted on the surface of the wooden floor of the container were almost all black and dark brown, and there were no light colors, especially light yellow that was similar to the color of wood. This problem arises because the main component of the glue used to impregnate the veneer paper and the veneer film is phenolic impregnating glue, and the phenolic impregnating glue is dark red, it is difficult to lighten it, so that the veneer impregnated with such glue The color of the face paper and face mask is black or dark brown. However, the wood color of the wooden floor is light yellow, so stick black and dark brown veneer paper and veneer film on the surface of the wooden floor. When the surface is damaged due to abnormal reasons during use, the veneer paper and ...
