The invention also provides a preparation method of the epoxy resin package adhesive. The epoxy resin package adhesive has the advantages of being low in viscosity, strong in operability, and high in reliability, and resisting high temperature and high humidity; the surface of a cured material has a matt effect; the packed LED brightness is high and soft, and the heat yellowness resistance and the UV yellowness resistance are superior.

The invention discloses a matte forming film, a preparation method thereof and a matte packaging material. The matte forming film comprises a matte layer, a core layer and a corona layer which are sequentially arranged, the weight ratio of the matte layer to the core layer to the corona layer is (0.8-1.2): (6-8): (1.5-2.2), and the matte layer, the core layer and the corona layer are prepared through a co-extrusion process. The matte packaging material comprises a plastic base material layer, a gloss oil layer and a matte forming film. According to the matte forming film, the preparation method of the matte forming film and the matte packaging material, the matte forming film can enable the packaging material to present a high-grade matte effect, cracking or appearance change does not occur during secondary forming, and the matte forming film is good in tensile strength, good in light transmission, long in corona retention time and capable of being well adhered to printing ink and glue. The matte forming film can replace matte ink to cover the surface of a pattern, can be used as a wear-resistant protective layer while providing a three-dimensional and matte high-grade effect, andprovides protection for a gloss oil pattern and a plastic base material layer.

Disclosed are a surface treating agent for a pearlylustre BOPP film and a preparation method therefor. The surface treating agent is prepared from the following raw materials in parts by weight: 2~4 parts of waterborne polyacrylate emulsion, 0.5~1.5 parts of waterborne anionic polyurethane dispersion, 1.2~2.5 parts of curing agent, 0.1~0.3 parts of ammonia water, 0.02~0.05 parts of wetting agent, and 6~10 parts of water. The surface treating agent forms a hard but flexible coat after cross-linking and curing on the surface of the BOPP film, and has outstanding adhesion force, water resistance and chemical resistance. By using the surface treating agent to modify the surface of the pearlylustre BOPP film, the pearlylustre of the BOPP film can be shielded, and the glossiness of the product can be reduced.

The invention discloses a preparation method of paper pulp with walnut shell as a raw material. The raw materials of the paper pulp comprise the following components, in parts by weight: 400-450 parts of walnut shell, 1-4 parts of a heat initiator, 1-4 parts of a defoaming agent, 2-8 parts of an oxidant, 10-20 parts of bentonite, 10-30 parts of oyster shell powder, 2-8 parts of medical stone powder, 2-8 parts of limonene, 2-8 parts of distillers' grain residue, 4-20 parts of toosedarin-containing plant insecticide, and 0.2-0.4 part of an auxiliary agent. According to the invention, waste is utilized, and the paper pulp is energy-saving and environmentally friendly. The paper pulp has special insect-resistant and antibacterial functions, and has long service life and high cleanness. With the paper pulp, worm damage and bacterium growth can be effectively prevented, such that collection and preservation are facilitated. The paper pulp has high safety, and the method has an important significance. The method can be widely popularized for application.

The invention discloses a whiteboard film matte UV paint and a preparation method thereof. The whiteboard film matte UV paint comprises the following components in parts by weight: 30-40 parts of high-functional polyurethane acrylate resin, difunctional polyurethane acrylate resin 5-10 parts of resin, 10-20 parts of UV reactive diluent, 3-5 parts of UV photoinitiator, 5-10 parts of silicone micropowder, 0.5-1 part of dispersant, 0.1-0.5 parts of leveling agent, 20-20 parts of solvent 30 servings. The invention uses high-functional urethane acrylate resin and difunctional urethane acrylate resin as main materials, adds organosilicon powder, and cooperates with other components to obtain matte UV paint for white board film. The whiteboard film matte UV coating has a matte effect, anti-glare, and is easy to write and erase. The whiteboard pen is easy to wet when writing, does not produce ink shrinkage, the font is clear, and easy to wipe, high hardness, high scratch resistance , good durability, very suitable for matte treatment and hardening treatment on the surface of whiteboard film.

The polyvinyl alcohol composition contains polyvinyl alcohol, a plasticizer, olefin-maleic anhydride copolymer microspheres, a lubricant and optional auxiliary agents; the plasticizer contains component A, component B and component C; the component A is one or more of glycerol, ethylene glycol, polyethylene glycol and pentaerythritol; the component B is magnesium chloride, magnesium nitrate, calcium chloride, copper sulfate and sodium acetate One or more; the component C is water. The present invention can make polyvinyl alcohol with a wide range of alcoholysis degree to be biaxially stretched into a film, and the obtained polyvinyl alcohol matte film has a matte effect, and also has suitable mechanical strength, surface wetting tension and Translucency.

The invention discloses a multi-dimensional decorative original edge wood grain ceramic brick and a preparation method thereof. The method comprises: A. pressing and forming a blank, and placing it in a roller kiln for drying to form a ceramic brick body; B. Matte surface glaze is applied on the brick body to form a matte surface glaze layer; C. Inkjet printing is performed on the matte surface glaze layer and deep ink is applied to form a composite layer of pattern decoration and deep ink; D. After pattern decoration and deep ink A matte transparent glaze is applied on the ink composite layer to form a matte transparent glaze layer; E 1 1. Apply dry glaze on the matte transparent glaze layer to form a dry glaze layer; F. Put it into a kiln for firing and molding to obtain multi-dimensional decorative original edge wood grain ceramic tiles.
