High-flame-retardance conductive foam gum and preparation process thereof

Abstract

The invention discloses high-flame-retardance conductive foam gum and a preparation process thereof. By virtue of scientific and orderly structure design, proportioning of base materials and operationprocedures, the prepared foam gum has both excellent flame retardance and conductivity. An overall thickness of a foam layer unit is 0.1 to 0.4 mm, so that the foam gum prepared in the invention hasthe buffering performance, also has the characteristic of ultrathin thickness, and is wider in application range. By arranging a PET conductive buffering foam layer base material and an EVA conductivebuffering foam layer base material, the foam layer unit is diversified in composition and is wider in application and excellent in buffering effect.

Description

technical field [0001] The invention belongs to the technical field of foam adhesive preparation, in particular to a highly flame-retardant conductive foam adhesive and a preparation process thereof. Background technique [0002] Buffer foam adhesive is a material with shock absorption, sound absorption and sealing effect, which is prepared from foam material as the base material through composite release materials. It is widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile phones Insulation, paste and sealing of accessories, industrial instruments, computers and peripheral equipment, auto parts, audio-visual equipment, toys, cosmetics, craft gifts, medical instruments, electric tools, office stationery, shelf display, home decoration, acrylic glass, ceramic products, etc. , anti-slip and cushioning shockproof. [0003] Currently, there are mainly the following problems: [0004] 1. Because the foam needs to have f...

AI Technical Summary

Problems solved by technology

[0004] 1. Because the foam needs to have flame retardant and conductive effects according to the functional requirements in the application process, the foam on the market usually has no obvious flame retardant and conductive properties, or the effect of combining the two is not satisfactory

[0005] 2. Traditional PE, PU and melamine foam have good cushioning and sound-absorbing properties, but due to the limitation of processing technology, it is impossible to obtain a high expansion ratio and ultra-thin cushioning foam material layer

The traditional processing technology can only get the buffer foam material layer above 1mm

[0006] 3. Because the foam substrate used in the traditional foam adhesive is too single, the application area of ​​the foam adhesive is narrow and the cushioning performance is not good.
