Description
Technical Field
The invention belongs to the field of hot melt adhesive films, and particularly relates to a hot melt adhesive film with a light storage effect.
Background
The hot melt adhesive film is produced by a coating method, the adhesive film needs to be matched with a layer of release material for supporting, and the release material is usually silicone oil paper. Even if some manufacturers call hot melt adhesive bare films, release paper is not attached to products in the market, but the products are produced by a coating method fundamentally, and the paper is rolled up and reused independently by cloth falling in the later stage. Even if the release paper can be used for 3 times, the demand of the release paper is reduced, about 250 tons of waste paper pollution can be generated by one coating machine every year, a large amount of silicone oil, whitening agent and other components are contained, and the production mode of the coating method matched with the release paper needs to be further changed. Whereas cast hot melt adhesive films are certainly the best choice. More importantly, the coating method uses the release paper as a support, and the release paper has thickness errors, so that the requirement on the thickness of the adhesive film is very accurate for customers, the fluctuation of the finished adhesive film is very large, and the finished adhesive film is difficult to control within 5 um. Because the fluctuation range of the release paper itself also exceeds 5um thickness. The influence of the release paper on the thickness of the product can be avoided without adopting a tape casting method for supporting the release paper, and the product with higher requirement on the production precision can be further produced.
Most common hot melt adhesive films in the market are soft rubber (TPU, polyester and the like) serving as main materials, the hardness is low, the mechanical strength is poor, the light storage effect is not achieved, and further improvement is needed.
