Problems solved by technology

With the advancement of production technology, people have higher and higher requirements for the performance and quality of anti-glare hardened film products. In addition to the basic performance requirements, some special properties are also required for the outermost hardened film, such as photovoltaic The anti-glare hardened film for power generation paper in the industry needs to have high light transmittance to better receive solar radiation, high hardness and high wear resistance to better protect devices, and anti-adhesive and release properties on the surface of the hardened film. There are also higher requirements to prevent dust, advertising stickers and other adhesive products from adhering to the film surface, which will affect the ability of the product to receive solar radiation, thereby affecting the effect of solar power generation
And for the anti-glare hardened film used on the outermost layer, if there are foreign objects on the surface of the product or other adhesive products are maliciously pasted by others, it will seriously affect the neatness and appearance of the product, and have a great impact on the follow-up cleaning work, making it difficult to satisfy downstream customers for a long time. Customer's requirements

Abstract

The invention relates to an anti-glare hardened film and a preparation method thereof. The hardened film comprises a silicone oil layer, an anti-glare hardened layer, a base material layer, and a hardened layer from top to bottom, wherein the thickness D1 of the silicone oil layer is the same as the anti-glare hardened layer. The average peak-to-valley depth Rz of the hardened layer is Rz-D1≥0.2 μm, and the water contact angle of the anti-glare hardened layer and the water contact angle of the silicone oil layer are 20°≤water contact angle of the silicone oil layer-water contact angle of the anti-glare hardened layer≤50 °. The hardened surface of the present invention is coated with a high-hardness anti-glare hardening solution and a silicone oil layer, so that the coating has excellent adhesive performance, and the coating has excellent anti-glare properties, high hardness, high wear resistance, and low release The characteristics of high release force can ensure that the product has good visual effect and scratch resistance, and at the same time, low release force can prevent others from arbitrarily pasting foreign objects on the film surface. The invention avoids the scratches caused by coating and winding, reduces the disadvantages such as scratches caused in the subsequent transportation and storage process, and better improves the apparent quality of the product.
