Gas mask composite material and production technology thereof

Abstract

The invention discloses a gas mask composite material. The gas mask composite material comprises the following raw materials in parts by weight: 55 to 65 parts of chlorinated butyl rubber, 10 to 20 parts of mixed three-dimensional network graphene, 5 to 10 parts of carbon black, 4 to 8 parts of dioctyl sebacate, 2 to 6 parts of an anti-aging agent, 1 to 3 parts of an accelerator EDC1 and 15 to 25parts of zinc chloride. According to the gas mask composite material, the bentonite in the modified chlorinated butyl rubber is of a layered structure, firstly, the bentonite is calcined and activatedto enhance the surface activity of the modified chlorinated butyl rubber, then the modified chlorinated butyl rubber and the nano modified liquid are stirred and react together, the nano modified liquid firstly adopts a coupling agent to modify nano silicon dioxide so that the nano silicon dioxide has an organophilic effect, and then the bentonite is modified through the coupling agent in the nano modified liquid so that the nano silicon dioxide is firstly attached in the layered structure of the bentonite, the nano silicon dioxide is high in activity and high in specific surface area and canbe used as an intermediate point to graft chlorinated butyl rubber and organic bentonite.

Description

technical field [0001] The invention relates to the technical field of gas mask mask materials, in particular to a gas mask mask composite material and a production process thereof. Background technique [0002] A gas mask is a personal special labor protection product, and it is also an individual protective product. It is worn on the head to protect people's respiratory organs, eyes and face, and is a personal protective equipment to prevent poisonous gases, dust, bacteria, toxic and harmful gases or steam and other toxic substances. . Gas masks are widely used in petroleum, chemical industry, mining, metallurgy, military, fire protection, emergency rescue, health and epidemic prevention, technology and environmental protection, machinery manufacturing and other fields, and can also play an important role in cities with severe smog and photochemical smog. Respiratory protection. Gas masks can be divided into full-face masks and half-masks in terms of shape, and full-face...

Problems solved by technology

[0003] The materials used in the existing gas mask masks have high gas permeability, and the weather resistance of the material is not good, which is easy to cause cracks, which further affects the gas permeability

[0004] The existing Chinese patent document publication number: CN104341685A discloses that it belongs to the technical field of gas mask masks, and is specifically a flame-retardant corrosion-resistant gas mask mask body rubber formula, which is composed of the following components by weight: 100 parts of chlorinated butyl rubber, 8-12 parts of zinc oxide, 0.3-0.5 parts of magnesium oxide, 1.5-2.0 parts of accelerator ZDC, 2-3 parts of anti-aging agent, 0.5-2 parts of chlorinated paraffin, 30-40 parts of reinforcing carbon black, phthalate 3-6 parts of dioctyl formate and 1.2-2 parts of stearic acid. The raw material uses chlorinated butyl rubber as the base material. Although chlorinated butyl rubber itself has weather resistance and low air permeability, other raw materials in the rubber compound are relatively Conventionally, the performance of the synthesized material is obvious, so further improvement is still needed
