Abstract

The invention relates to a fiber insulation board preparation method. The fiber insulation board preparation method comprises the following steps of (1) evenly mixing first polyester short fibers and fibers A, (2) conducting opening and combing on the mixed fibers to form a fiber net, (3) evenly spraying phosphorous-nitrogen-based flame retardant or phosphorous-based flame retardant which is 2%-10% of the total mass of the fibers on the surface of the fiber net, and (4) obtaining a fiber insulation board after the fiber net processed through the step of (3) is needled, pressed in a rolling mode and set in a heat mode. The fiber insulation board preparation method is simple in technology, no adhesive is added in a production process, physical bonding is only formed through melting and adhesion of raw materials, no pollution is generated to environment, and the board does not release hazard substances under the influence of high temperature and belongs to environment-friendly type materials. In addition, holes exist among fibers, air can be stored in the fibers as insulation materials, and a good insulation effect is achieved. Needling holes are formed in the surface of the fiber board, a sound absorption function is achieved, and interference of environmental noise is effectively reduced.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of a novel fiber insulation board. Background technique [0002] The insulation materials used in the existing fiber insulation boards include inorganic insulation materials and organic insulation materials. [0003] Common inorganic thermal insulation materials mainly include glass wool, rock wool, expanded perlite, micro-nano insulation boards, etc. Although inorganic thermal insulation materials can meet the standard of fire protection class A, the use of glass wool is not environmentally friendly and can easily cause itching to the human body; the production of rock wool is harmful to the human body; expanded perlite has a large weight and high water absorption; micro-nano heat insulation The price of the board is expensive, so there will be disadvantages in its use. [0004] Common organic insulation materials mainly include polyurethane foam, polyst...
