A kind of total heat exchange graphene paper film

Abstract

The invention provides a kind of total heat exchange graphene paper film, raw materials include plant fiber slurry, high molecular polymer, flame retardant, antibacterial agent and graphene water-based slurry; the plant fiber slurry is imported coniferous wood pulp or A mixed slurry of imported softwood pulp and hardwood pulp; the graphene water-based slurry: the active ingredient content is 5-15%, and the viscosity is 1000-6000mpa.s; raw materials also include polyacrylamide, cationic starch, carboxymethyl At least one of the base cellulose sodium, the addition amount is 2-5% relative to the dry fiber content. The raw material also includes at least one of polyacrylamide, cationic starch, and sodium carboxymethyl cellulose, and the added amount is 2-5% relative to the dry fiber amount. The mass ratio of the high molecular polymer to the flame retardant is 1:4-10. The air permeability of the total heat exchange graphene paper film of the present invention is ≤0.2μm / Pa·s, and the moisture permeability is ≥1000g / m 2 24h.

Description

A kind of full heat exchange graphene paper membrane technical field The invention belongs to special paper technical field, relate in particular to a kind of full heat exchange graphene paper film. Background technique Air conditioner works indoors in a building, if airtight is not ventilated, and indoor and outdoor ventilation is not performed for a long time, the air will become It gets dirty, so it needs to be constantly exchanged with fresh outdoor air. The total heat exchanger is the key to the energy exchange of the fresh air system. The key factor, the use of total heat exchanger to complete the energy exchange between indoor and outdoor air is a commonly used method at home and abroad. The effect influencing factors of total heat exchanger mainly include the following: Sensible heat: the heat absorbed or released along with the temperature change of moist air, utilizes fresh air, exhaust air temperature difference to recover sensible heat. heat.
