A new type of heat-resistant and flame-retardant foam and its preparation process

Abstract

The invention discloses a new type of heat-resistant and flame-retardant foam, which is characterized in that it comprises: PET ultra-thin buffer foam layer base material, antibacterial layer, moisture-proof layer, heat-resistant and flame-retardant layer, aluminum foil cloth and embossed release Model paper; the outer side of the PET ultra-thin buffer foam layer substrate is surrounded by an antibacterial layer; the outer side of the antibacterial layer is surrounded by a moisture-proof layer; the outer side of the moisture-proof layer is surrounded by a heat-resistant flame-retardant layer; the heat-resistant The outer side of the flame retardant layer is surrounded by aluminum foil cloth; one side of the aluminum foil cloth away from the heat-resistant flame retardant layer is provided with embossed release paper. The present invention is provided with a heat-resistant flame-retardant layer, an antibacterial layer and a moisture-proof layer so that the foam has excellent heat-resistant flame-retardant, antibacterial and moisture-proof effects. And keeping the overall thickness of the PET ultra-thin cushioning foam layer substrate at 0.25~0.4mm makes the polymer foam described in the present invention more able to have light and thin characteristics while shock absorption, and expands the application of foam Scope, to solve the practical application needs.

Description

technical field [0001] The invention belongs to the technical field of foam preparation, and in particular relates to a novel heat-resistant and flame-retardant foam and a preparation process thereof. Background technique [0002] Buffer foam is a material with shock absorption, sound absorption and sealing effect prepared by composite release material with foam material as the base material. It is widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories, Insulation, paste, sealing, anti-slip of 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. And cushion shockproof. [0003] In terms of cushioning and shock absorption of electronic products, especially the shock absorption at the bottom of electronic d...

AI Technical Summary

Problems solved by technology

[0005] 1. Traditional PE, PU and melamine foams have good cushioning and sound-absorbing properties, but due to the limitation of processing technology, it is impossible to obtain a high foaming ratio and ultra-thin cushioning foam material layer. The traditional processing technology can only obtain 1mm The above buffer foam material layer;

[0006] 2. Since the current industrial working environment is mainly cold and humid, and many application environments of foam are often not ideal, it is easy to breed bacteria, causing foam to be corroded, and the paper tubes on the market are not antibacterial and moisture-proof. Efficacy, which reduces the application range of foam;

[0007] 3. Since the foam is a plastic product, and the ignition point of the plastic is low, it is very easy to be ignited by sparks during the application process, thus causing a fire, and the foam on the market has no flame-retardant effect;

[0008] 4. Due to the wide range of foam applications and large losses, the used foam is often discarded directly, which not only causes environmental problems, but also causes insufficient resource utilization and waste of resources
