Abstract

The invention discloses a preparation method of a silica gel film capable of being bonded with other plastic materials, which comprises the following steps: S1, preparing a bottom film: producing a TPU (Thermoplastic Polyurethane) hot melt adhesive base film for later use by adopting a TPU hot melt adhesive raw material through a vacuum hot press molding technology; S2, preparing an adhesive: taking a thermosetting adhesive to dilute the viscosity, and standing for later use; S3, preparing liquid silica gel: taking AB double-component liquid silica gel according to a certain ratio, putting theAB double-component liquid silica gel into a stirring kettle, stirring for 10 minutes, and standing for later use; S4, defoaming: putting the prepared liquid silica gel into a vacuum defoaming machine, and defoaming the liquid silica gel for 2 hours; and S5, coating and laminating. The silica gel film is scientific and reasonable in structure and safe and convenient to use. The base film is prepared, the liquid silica gel is applied to form a film, and the base film and the film forming silica gel are adhered, such that the whole stability of the product can be ensured, the peeling due to insufficient adhesion fastness is avoided, the adhesion fastness stability is improved, the process is simplified, the process control is easily achieved, the processing convenience can be substantiallyimproved, and promotion and application are facilitated.

Description

Technical field [0001] The invention relates to the technical field of silica gel membranes, in particular to a silica gel membrane capable of bonding other plastic materials and a preparation method thereof. Background technique [0002] In the past ten years, due to its excellent physical properties and environmental protection performance, silica gel materials have been rapidly developed in the automotive industry, electrical and electronic industries, and textile fields. Liquid silica gels contain nitrogen, phosphorus, sulfur, tin, lead, mercury, and alcohol. After contact or mixing, the liquid silicone cannot be cured or cured completely. Therefore, in the plastic materials industry, how to bond the silicone with the plastic material is a difficult problem. Summary of the invention [0003] The present invention provides a silica gel film capable of bonding other plastic materials and a preparation method thereof, which can effectively solve the problem of how fastness of the...
