Abstract

The invention discloses a dehumidifying rotor manufacturing environmental pulp fiber composite board. The dehumidifying rotor manufacturing environmental pulp fiber composite board is composed of, by weight percentage, 30%-40% of non-asbestos mineral fiber, 8%-20% of carbon fiber, 8%-20% of polyester fiber, 5%-15% of wood pulp, 5%-15% of straw pulp, 5%-15% of bamboo pulp, 8%-15% of brominated flame retardant, 5%-10% of sizing agent and 5%-10% of auxiliaries. The dehumidifying rotor manufacturing environmental pulp fiber composite board is prepared from the environmentally-friendly raw materials and can improve the strength and tenacity, and meanwhile through the fire retardant, prolong the service life of dehumidifying rotors.

Description

technical field [0001] The invention relates to the field of manufacturing dehumidification rotors, in particular to an environment-friendly pulp fiber composite paperboard for manufacturing dehumidification rotors. Background technique [0002] Rotary dehumidifiers are often used in underground buildings, pharmaceuticals, food, operating rooms and other occasions. They operate in conjunction with air conditioning systems to bring the environment to the required temperature and humidity. As the core component of the rotary dehumidifier, the raw material of the dehumidification wheel, that is, the quality of the cardboard directly determines its dehumidification effect. However, the existing cardboard often has the problems of low strength and poor toughness. [0003] At the same time, nearly 80% of the flame retardants used in the dehumidification wheel are halogen-containing flame retardants, among which polybrominated diphenyl ethers and polybrominated biphenyls are the r...
