Abstract
The present disclosure provides a fire extinguishing air bubble film filled with a gaseous fire-extinguishing medium, and a manufacturing method therefor. The fire extinguishing air bubble film includes a double-layer air bubble film base material and buffer air bubbles distributed in the double-layer air bubble film base material and internally filled with the gaseous fire-extinguishing medium, where the air bubble film base material is prepared from polyethylene as a base material and auxiliary materials in a specified weight ratio.
Claims2
A fire extinguishing air bubble film filled with a gaseous fire-extinguishing medium, comprising a double-layer air bubble film base material (1) and buffer air bubbles (2) distributed in the double-layer air bubble film base material (1) and internally filled with the gaseous fire-extinguishing medium, wherein the air bubble film base material (1) is prepared from polyethylene as a base material and auxiliary materials in a specified weight ratio;
- wherein the auxiliary materials comprise a resin, a biodegradable additive, a plasticizer, a flame retardant, an anti-block agent, and a whitening agent;
- wherein the polyethylene, the resin, the biodegradable additive, the plasticizer, the flame retardant, the anti-block agent, and the whitening agent have a weight ratio of (5-65):(5-35):(1-20):(1-10):(0.1-5):(0.1-3):(0.1-2);
- and
- wherein the polyethylene is any one or a mixture of three selected from the group consisting of low-density polyethylene, linear low-density polyethylene, and high-density polyethylene;
- the resin is any one selected from the group consisting of a PVC (polyvinyl chloride)-SC5 resin and a PVC (polyvinyl chloride)-SG4 resin, with a degree of polymerization at 1,000 to 1,200;
- the biodegradable additive is a BDP (biodegradable plastics) fully-biodegradable additive;
- the plasticizer is any one selected from the group consisting of dibutyl phthalate, dioctyl phthalate, tricresyl phosphate, and chlorinated paraffin;
- the flame retardant is a DOPO (9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide) flame retardant;
- the anti-block agent is a PE film anti-block agent;
- and the whitening agent is any one selected from the group consisting of a fluorescent whitening agent OB (2,5-bis(5-tert-butyl-2-benzoxazolyl)thiophene) and a fluorescent whitening agent OB-1 (styryl bisbenzoxazole).
