Flame retardant silica gel foam adhesive tape

Abstract

The invention discloses a flame retardant silica gel foam adhesive tape, which comprises 70%-90% of flame retardant silica gel foam, 0.2%-1.3% of an adhesive, 1%-5% of a high temperature resistant material, 5%-15% of a flame retardant glue, and 5%-15% of a release film. The flame retardant silica gel foam adhesive tape has strong flame retardance, meets the simple process requirement of low cost manufacturing, and is convenient for large-scale popularization and use. The product is convenient for bonding and firm in itself, has a novel structure, and is easy to use. The product has superior performance and flame retardance, and is suitable for thermal insulation, vibration isolation, sound insulation and other applications. The adhesive tape has the characteristics of excellent compressionresistance to permanent deformation, low flame, low smoke, low smoke toxicity and the like.

Description

technical field [0001] The invention relates to a flame-retardant silicone foam adhesive tape. Background technique [0002] Foam is a material made of foamed plastic particles, referred to as foam. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, PORON, CR, EVA, bridging PE, SBR, EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, convenient use, free bending, ultra-thin volume, and reliable performance. Foam tape is made of EVA or PE foam as the base material, coated with solvent-based (or hot-melt) pressure-sensitive adhesive on one or both sides, and then coated with release paper. It has the function of sealing and shock absorption. It has excellent sealing performance, compression deformation resistance, flame retardancy, wettability, etc. Products are widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile ph...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of electronic products, the performance requirements are becoming more and more stringent. Foam products are widely used in electronic products. The existing foam products are mainly ordinary PU foam and hot melt adhesive are pasted together by mold heating. It is made of EVA or PE foam as the base material, coated with solvent-based pressure-sensitive adhesive on one or both sides and then coated with release paper. It has the functions of sealing, cushioning and shock absorption, but the existing foam exists The installation and fixation of the foam is inconvenient to use, and the foam is easy to shift if the fixation is not firm, which affects its cushioning protection; the cushioning performance of the foam itself is poor, and it cannot meet the needs of the use of electronic products. Therefore, silicone foam products meet their needs

[0004] However, the traditional silicone foam tape has poor flame retardancy, especially the selection of its raw material components makes it more expensive and complicated, which cannot meet its comprehensive needs.
