Abstract

The invention relates to the field of composite materials and particularly discloses a novel pressure-sensitive adhesive composite material and a preparation method thereof. The novel pressure-sensitive adhesive composite material comprises a body paper layer and a face paper layer, wherein the body paper layer comprises Glassine body paper as well solvent-free solution and an environment-friendly adhesive which are sequentially coated on one surface of the Glassine paper. The preparation method comprises the following steps of: after processing the Glassine body paper by utilizing the solvent-free solution, coating the environment-friendly adhesive, immediately covering one glued face of body paper with the face paper after drying the Glassine body paper to a certain degree, carrying out press fit by utilizing a rubber roller and a rolling drum, and drying so as to obtain the novel composite material. According to the novel pressure-sensitive adhesive composite material and the preparation method, since the body paper is processed by utilizing a PE (polyethylene)-free film and silica paper is processed by utilizing the solvent-free solution, the production is safe, the health risk is avoided, the energy can be saved, and the vehicle speed of the coating can be increased; besides, the composite material is good in heat resistance and ageing resistance and hardly tilts in a use process, and phenomena such as shrinkage, corrugation, deformation and yellowing do not appear at the high and low temperatures, so that the service life of the composite material is long.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a novel pressure-sensitive adhesive composite material and a preparation method thereof. Background technique [0002] With the continuous development of society, composite materials have been more and more widely used in production and daily life, especially pressure-sensitive adhesive composite materials, which are used in more than a dozen industries, including medicine, food, daily chemical and other industries. At present, pressure-sensitive adhesive composite materials in the international market usually use base paper as the base paper, coat PE film on the surface of the base paper, and then coat silicone oil on the surface of the PE film. The working fluid of silicone oil is silicone oil with solvent, and its performance cannot reach The physical indicators of environmental protection, the volatilization of solvents during processing consumes heat energy, high energy co...
