Problems solved by technology

[0004] When the base paper is produced, a large amount of titanium dioxide (about 35% on average, up to 45%) needs to be added to meet the whiteness requirements, thereby improving opacity, and it is necessary to consider the absorption and permeability of the base paper to choose various types of titanium dioxide. The cost of additives and paper fiber itself is not high, but the comprehensive formula of ingredients and production process makes the price of the base paper very high
In order to reduce the purchase cost of base paper, we directly purchase low-whiteness white paper and only coat it with melamine glue. The opacity of the decorative white paper can only reach about 0.75-0.88, and its covering ability to the original color of furniture is very poor.

Embodiment 1-9

[0049] Embodiment 1-9: A coating glue solution for decorative paper, consisting of melamine glue and titanium white solution, the components included and the corresponding quality are shown in Table 1, and prepared by the following steps:

[0050] S1: Pour water and titanium dioxide into a mixing tank and stir evenly to obtain a mixed solution A;

[0051] S2: Add wetting agent and dispersant to mixture A, and grind once in a horizontal grinder to obtain mixture B;

[0052] S3: adding zeolite powder and water-soluble amino acid into the mixed solution B, stirring and mixing evenly to obtain titanium white solution;

[0053] S4: Mixing the titanium dioxide solution and the melamine glue to obtain a coating glue solution.

[0054] Table 1 embodiment 1-9 component and corresponding mass (kg)

[0055]

[0056] In the above examples, Chemours Titanium Dioxide R-796+ was used as the titanium dioxide, 80-100 mesh as the zeolite powder, and PE-100 was used as the wetting agent.

Embodiment 10

[0066] Embodiment 10: a kind of preparation method of coating glue, comprises the following steps:

[0067] S1: Pour water and titanium dioxide into a mixing tank and stir evenly to obtain a mixed solution A;

[0068] S2: Grind the mixed solution A twice in a horizontal grinder, then add the wetting agent and dispersant to the mixture A, and grind it once in the horizontal grinder to obtain the mixture B;

[0069] S3: adding zeolite powder and water-soluble amino acid into the mixed solution B, stirring and mixing evenly to obtain titanium white solution;

[0070] S4: Mixing the titanium dioxide solution and the melamine glue to obtain a coating glue solution.

Embodiment 11

[0071] Example 11: A preparation method of coating glue, the difference from Example 10 is that in S2, before adding the wetting agent and dispersant to the mixture A, the mixture A is ground three times in a horizontal grinder.

Abstract

The invention discloses a coating glue solution for decorative paper and a preparation method of the coating glue solution, belongs to the technical field of decorative paper production and aims to solve the problem that existing coating glue cannot improve the opacity of body paper. The coating glue solution is composed of melamine glue and a titanium white solution according to the weight part ratio of 1:(0.1-0.2), wherein the titanium white solution comprises, by weight, 45-55 parts of water, 45-55 parts of titanium dioxide, 3-5 parts of dispersing agent, 0.5-1.2 parts of wetting agent and2.5-5 parts of acrylic resin. According to the preparation method, through mixing of the titanium white solution and the melamine glue in cooperation with the dispersing agent and the wetting agent, the milk-white coating glue solution is obtained; and when the surface of the body paper is coated with the titanium dioxide, the whiteness and opacity of the body paper are improved, so that the decorative white paper with qualified opacity is obtained.

Description

technical field [0001] The invention relates to the technical field of decorative paper production, in particular to a coating glue solution for decorative paper and a preparation method thereof. Background technique [0002] Decorative paper is an essential raw material in many building materials, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards and floors. It mainly plays the role of providing pattern decoration and covering to prevent the bottom glue from seeping out. Among the decorative papers, there is a mainstream product of white decorative paper, which can be directly pasted on the surface of furniture. The finished product needs to have a high whiteness and an opacity above 0.9 to cover the original color of the furniture. [0003] In the prior art, it is generally used as the base paper by directly purchasing white paper that reaches the standard of whiteness. When using the base paper to prepare the...
