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.
