Problems solved by technology

[0002] The existing laminating process uses LEPD to melt directly on the paper through the high-temperature melting of the film head of the laminating machine, seal the gaps in the paper, and then coat it with silicon. The thermal performance is not very good, and the flame retardant effect is not good

Abstract

The invention discloses high-temperature-resistant paper which is prepared from the following raw materials in parts by weight of dry substances: 70-100 parts of low-density polyethylene plastic particles, 10-50 parts of high-density polyethylene plastic particles, 1-5 parts of brominated flame retardants, 3-10 parts of hot melt glue and 2-5 parts of stabilizers. The invention also discloses a preparation process of the high-temperature resistant paper. Given the shortcomings of the original technology, the density of the low-density polyethylene is increased, and the coating density is increased along; and therefore, the water vapor transmission rate is reduced, the brightness, stiffness and tensile strength of the flame retardant paper are improved, high-quality flame retardant paper is obtained, and customers are highly satisfied.
