An electrician safety cap resistant to high and low temperatures and high in hardness and a preparing method thereof

Abstract

The present invention relates to the field of communications, in particular to a high-low temperature resistant high-hardness electrical safety helmet and a preparation method thereof, the components of which include: natural rubber, silicon rubber, polyurethane rubber, chlorinated polyethylene rubber, and tetramethylthiuram monosulfide , quaternary phosphorus salt, anti-aging agent, polycarbo resin, dioctyl phthalate, desulfurizer, p-methyl sulfate urea, diallyl phthalate; the rubber electrician safety helmet prepared by the present invention not only It has the advantages of strong antistatic ability, good aging resistance and water resistance, as well as high hardness and high and low temperature resistance; the vacuum of the dispersion cylinder makes the mixture more evenly dispersed, mixed more fully, and the product performance is more stable; the reaction kettle The interior is in a high-temperature vacuum state, which significantly improves the toughness, antistatic ability and water resistance of the prepared rubber electrician's safety helmet; the cooling in the water bath of the ice-water mixture makes the molding time of the prepared rubber electrician's safety helmet short, and the water resistance and property after molding Hardness is significantly improved.

Description

technical field

[0001] The invention relates to the field of communications, in particular to a high-low temperature resistant high-hardness electrical safety helmet and a preparation method thereof. Background technique

[0002] The safety helmet is a shallow dome hat made of steel or similar materials worn to protect the top of the head, and it is a protective product to prevent impact objects from hurting the head. Consists of shell, lining, lower chin strap and rear hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the striking object is mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. Impact absorption performance, puncture resistance performance, lateral rigidity, electrical insulation, and flame retardancy are the basic technical performance re...
