preparation example Construction

[0043] The specific embodiment part of the present invention also provides a kind of preparation method of above-mentioned adhesive glue, and described method comprises the following steps:

[0044] (1) Propylene glycol methyl ether acetate, cyclohexanone, and tetramethylbenzene are mixed to obtain a mixed solvent, and tertiary hydroxyl chloride resin and acrylic resin are added in the mixed solvent to obtain a resin solution;

[0045] (2) adding fumed silica to the resin solution obtained in step (1), grinding and dispersing to obtain a semi-finished adhesive;

[0046] (3) Adding a defoamer to the adhesive semi-finished product obtained in step (2) to obtain an adhesive for in-mold decoration.

[0047] In order to facilitate understanding of the present invention, the present invention enumerates the following examples. It should be clear to those skilled in the art that the embodiments are only for helping to understand the present invention, and should not be regarded as spe...

Embodiment 1

[0049] A preparation method of adhesive glue for in-mold decoration, said preparation method comprising the following steps:

[0050] (1) 5% propylene glycol methyl ether acetate, 40% cyclohexanone, and 20% tetramethylbenzene are mixed to obtain a mixed solvent, and 25% tertiary hydroxychloride resin and 5% acrylic acid are added to the mixed solvent under stirring at 800r / min Resin, continue to stir 2h, obtain resin solution;

[0051] (2) Add 4% fumed silica to the resin solution obtained in step (1) under stirring at 600r / min, continue stirring for 15min, grind and disperse, and obtain a semi-finished adhesive;

Abstract

The invention relates to an adhesive for in-mold decoration. The adhesive for in-mold decoration is prepared from, by mass, 5-10% of propylene glycol methyl ether acetate, 30-40% of cyclohexanone, 15-20% of tetramethylbenzene, 20-25% of ternary hydroxyl chloride vinyl acetate resin, 5-10% of acrylic resin and 2.5-5% of assistant. The adhesive has excellent adhesive force, a cross-cut tester test is carried out, the 5B grade is reached, good printability is achieved, no poor printing phenomena such as orange peel and poor defoaming are generated, and good temperature resistance and high temperature and high humidity resistance are also achieved.

Description

technical field [0001] The invention belongs to the field of materials, and relates to an adhesive and a preparation method thereof, in particular to an adhesive for in-mold decoration and a preparation method thereof. Background technique [0002] In-Mould Decoration (IMD) has been rapidly adopted in the plastic processing industry around the world since it was industrialized in Japan. Its decorative design is beautiful, diverse, low in cost, free of spraying and other advantages, which make the IMD process very popular. The IMD process can also design 3D patterns, which cannot be replaced by the traditional spraying process; at the same time, IMD is a spray-free process, and the ink utilization rate is much higher than that of the spraying process. As the country and society have higher and higher environmental protection requirements, IMD will gradually Replace part of the spraying process. With the gradual development of IMD technology, it has gradually developed from ...
