Embodiment 1

[0017] Embodiment 1: Preparation of PVC decorative film surface treatment agent

[0018] Each component is weighed according to the following weight percentage:

[0019]

[0020] Wherein, the matting agent is silica matting powder; the hand feeling agent is silicone or acrylic slip agent; the curing agent is aziridine crosslinking agent cross-linked with isophorone diisocyanate The compound of the linking agent, the mass ratio of the aziridine crosslinking agent to the isophorone diisocyanate crosslinking agent is between 1:10 and 1:2; the scratch-resistant agent is silicone oil; the The leveling agent is a polyether modified organosilicon compound; the defoamer is an acrylic modified compound.

[0021] Stir the water-based polyurethane emulsion evenly until no solid phase substance is precipitated at the bottom of the emulsion, then add defoamer, matting agent, hand feeling agent, scratch-resistant agent and leveling agent to the water-based polyurethane emulsion, stir fo...

Embodiment 2

[0022] Example 2: Preparation of ultra-matte scratch-resistant PVC decorative film

[0023] 1) Take two or three kinds of PVC base film, PVC printing middle layer film and PVC matting mask and compound them sequentially to obtain a PVC composite film, and then use a matte wheel to perform preliminary embossing and matting treatment to control the glossiness at 20~ between 60°;

[0024] 2) Using a coating machine, the PVC decorative film surface treatment agent prepared in Example 1 is coated on the surface of the PVC composite film, and the thickness of the coating is adjusted by using the upper rubber roller and the scraper, and the thickness of the coating is controlled at 0.02 ~0.10mm to ensure good toughness and tensile properties of the treated layer;

[0025] 3) Utilize the coater body of furnace to cure and dry the PVC composite film after the surface treatment agent for PVC decorative film is surface-coated, in order to ensure that the surface treatment agent is compl...

Abstract

The invention discloses a PVC (polyvinyl chloride) decorative film surface treating agent and a PVC decorative film treated with the same. The surface treating agent comprises the following components in percentage by weight: 80.0-92.0% of water-based polyurethane emulsion, 2.0-4.0% of flatting agent, 0.5-1.5% of defoaming agent, 0.5-1.0% of hand feeling agent, 4.0-8.0% of curing agent, 0.1-0.3% of scraping inhibitor, 0.3-1.3% of leveling agent and 2.0-10.0% of water. The PVC decorative film treated with the surface treating agent has the advantages of excellent matte performance, scraping resistance, favorable compatibility with other decorating materials, and the like, and feels soft.

Description

technical field [0001] The invention relates to a PVC decorative film surface treatment agent, a PVC decorative film surface-treated by the surface treatment agent and a preparation method thereof. Background technique [0002] The traditional matte series PVC decorative film is made of multiple layers of PVC films with different properties. In order to achieve a matte effect, a layer of matte film is usually attached to the surface, and then embossed at high temperature to achieve matte effect. Purpose. Although this method has a certain matting effect and function, it is still difficult to achieve an ultra-matte gloss effect. [0003] Matte series PVC decorative films are mostly used in home decoration, home appliances, furniture, automotive interiors and other products, so it needs to be able to cope with various wiping, slight collisions and wear in the process of material processing and application in daily life, and the product's scratch resistance The better the rub...
