Abstract

The invention relates to a high-stability UV adhesive, belonging to the adhesive field. As that brewer's grains are used as raw materials, the brewer's grains are mixed and soaked in alkali solution,so that the crude fibers in the brewer's grains are preliminarily defibrillated to form a support structure of a hollow shell layer. The production of the structure can improve the bite force betweenthe brewer's grains and the modified hydrotalcite component and the high molecular component, thereby achieving the effect of improving the internal mechanical properties; cetyltrimethyl ammonium bromide is used as modifier, the layered magnesium-aluminum hydrotalcite is modified, so as to be beneficial for high molecular viscous substances and other components to enter the interlayer structure, the interlayer structure of the hydrotalcite is spread out in the curing process to achieve the peeling effect, and the hydrotalcite is combined organically in the blending process of the gel made of polyethylene resin and the modified hydrotalcite, so as to effectively improve the stability and mechanical properties of the composite system. The invention solves the problems of poor stability and internal mechanical properties of the UV adhesive commonly used at present.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a high-stable shadowless adhesive. Background technique [0002] We know that in the field of advertising, the general way of posting advertisements is to first spray the advertisement content on one layer of the inkjet film with an inkjet printer, and then paste it on the wall with ordinary latex or double-sided tape on the other layer of the inkjet film. On one hand, on advertising boards and other carriers, this method has complicated construction procedures on the one hand, and on the other hand, when removing advertisements, the latex or double-sided tape used tends to leave residual glue, is not easy to peel off, and can only be used once . In addition, the above method can only achieve single-sided inkjet painting, and for transparent glass windows, if it is used as a carrier for advertising, it needs to be constructed externally, which will have a certain impact on the advertisi...
