For 8-12 μm of chopped oxidization fiber fiber.
Further, described adhesive is that the markets such as acrylic compounds, polyvinyl alcohol, phenolic, ureaformaldehyde class or wood glue class are common
Water-soluble resin glue one or more of mixtures with arbitrary proportion.
Further, described adhesive is organic fiber, and the glass fibre, oxidization fiber fiber are by the organic fiber warm
It is mutually bonded after molten.
Further, the organic fiber is the mixture of polyethylene, one kind of polypropylene or polyester or arbitrary proportion.
In addition, including the following steps: will be above-mentioned the present invention also provides the production method of a kind of sound-absorption and heat-insulation paper or felt
Sound-absorbing insulation material carries out dispersion slurrying, molding, sizing, drying, winding acquisition finished product.
In addition, the present invention also provides sound-absorption and heat-insulation paper or sound-absorption and heat-insulation felt using above method production.
Its physics of inorfil, good mechanical property, flexibility the beneficial effects of the present invention are: oxidization fiber fiber compares
Height, the paper (felt) produced after mixing with inorganic glass fiber using wet process papermaking process, is just provided with inorganic glass fiber
The characteristic that paper (felt) does not have overcomes all-glass paper (felt) easy to tear, not impact resistance, not withstand pressure, not wear-resisting, mechanical strong
Low, the disadvantages of being also easy to produce glass fiber dust is spent, further improves sound absorbing performance, heat-proof quality, heat-resisting alternation performance, significantly
Application range and application field are improved, and is provided with some excellent properties of organic material.
