Problems solved by technology

[0007] At present, there is no clear production technology and related research and development for all-heat fresh air paper. The manufacturers mainly use paper made of wood pulp fibers using special processes, but the moisture permeability, air tightness, tear resistance, The ability of anti-aging and anti-mildew is uneven. At present, the heat exchange efficiency of the product is low, which is not enough to save environmental protection
The main reason is that the gap between fibers is not well controlled, and only water vapor molecules with smaller particle sizes can pass through, and other harmful gas or odorous gas molecules with larger particle sizes cannot pass through.

Embodiment 1

[0061] The composition of raw materials is as follows:

[0062]

[0063] The preparation method is as follows:

[0064] (1) The sea-island fibers are pretreated with sodium hydroxide solution, the concentration of the sea-island fibers is 6%, heated and stirred at 95°C for 30 minutes, and then washed with water for later use. The treatment of the sea-island fibers directly affects the moisture permeability;

[0065] (2) After the sea-island fiber after treatment, bleached kraft softwood pulp, and broadleaf bleached chemical wood pulp are mixed, they are put into a beater and diluted with water for beating, and the beating degree is 24.5 ° SR to obtain a slurry;

[0066] (3) Mix the slurry obtained in step (2) with wet strength agent PAE, paper stiffness agent methyl methacrylate, antifungal and fungicide isothiazolinone derivatives, aluminum sulfate, stir and mix for 1 hour, and mix The slurry is copied and dried by an inclined wire paper machine to obtain semi-finished ba...

Abstract

The invention belongs to the technical field of papermaking and particularly relates to brand-new fresh-air paper and a preparation method thereof. The brand-new fresh-air paper is prepared from the following raw materials: sea-island fiber, bleached sulfate softwood pulp, bleached broad-leaf chemical wood pulp, a wet strength agent, an adhesive, a moisture-absorption additive and an aid. The brand-new fresh-air paper is good in moisture permeability and is capable of well replacing moisture; the paper is good in gas tightness and capable of blocking carbon dioxide, harmful gas and viruses; the paper is good in evenness and high in binding force, has good tear resistance and stiffness and is convenient to form; and the paper has sufficient ageing resistance and mold resistance, a formed product can be well used, and the secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a full heat fresh air paper and a preparation method thereof. Background technique [0002] Since the energy crisis in the 1970s, buildings have been built more and more airtight to reduce the loss of indoor heat or cooling, but the consequence is that indoor harmful air is generated due to insufficient fresh air. The gas cannot be properly diluted and released, resulting in an indoor environment with a high degree of chemical pollution and bacteria and fungal reproduction. It is a generally accepted fact that the air pollution levels in an air-conditioned, poorly ventilated space are several times higher than in the air outside. The concentration of air pollution indoors is higher than outdoors, and most people spend 85% to 90% of their time indoors, which makes them vulnerable to diseases caused by these air pollutions. In recent years, more and more people li...
