Abstract
The invention relates to a waste wool low-temperature melting method used for sound-absorption heat-insulation building materials. Leftovers formed during the wool carding process of a wool spinning enterprise are used by the waste wool low-temperature melting method used for the sound-absorption heat-insulation building materials, and slag of the leftovers is removed, and the leftovers are combed and are sorted; or used wool products are opened and loosened, impurities of the wool products are removed, and the wool products are sorted, then the wool products are mixed with moderate low melting point fiber with the melting point of 110 Celsius degrees, and therefore heat-insulation sound-absorption materials applied to construction material standard are made through sizing and compressing procedures. The waste wool low-temperature melting method used for the sound-absorption and heat-insulation building materials is low in energy consumption and short in technical progress.
Description
Technical field
The present invention relates to a kind of low temperature fusion method based on waste and old wool, belong to building and field of textiles.
Background technology
Development speed and the scale of Building Trade in China occupy first place in the world, the annual newly-increased building area of China is up to hundred million square metres of 18-20, but belong to the highly energy-consuming building more than 95%, year energy consumption surpasses 1/4th of national total energy consumption, and the materials for wall heat-insulating property is poor is main cause.Traditional thermal insulation material mainly contains the mineral wool materials such as rock wool, glass wool, aluminium silicate wool; The organic foam plastics such as polyurethane, polystyrene, phenolic resins, rubber and plastic.Wherein, rock wool and glass wool belong to inorganic mineral class material, and its main raw material are inorganic minerals, and these mineral are all the nature differentiation of 10000000 year, and are non-renewable; The mineral wool material needs to consume a large amount of energy in the manufacturing process of high-temperature fusion " fibroblast "; Use phenolic resins as cementing agent when moulding, environment is had certain pollution; Produce and use procedure in, easily cause the producer, constructor and user's respiratory tract infection and allergic; The mineral wool material can not be recycled after use, because they are nondegradable nature of glass refuses, common processing method is landfill, but after landfill, they not only can not be degraded, and organic binder wherein also causes long-term pollution to underground water.The thermal insulation material of organic is such as the main raw material(s) of the foamed plastics such as polyurethane, polystyrene, phenolic aldehyde, rubber and plastic is all the downstream product of petroleum industry, its cost is higher, price fluctuation is larger, fire resistance is relatively poor simultaneously, when it uses as thermal insulation material, only have thermal-insulation function and do not have the sound absorption function.Leftover bits and pieces in producing take wool spinning and waste and old wool fabric can " be turned waste into wealth " as primary raw material, reduce the waste of resource.But at present that the method energy consumption of wool set moulding is large, long flow path.
Summary of the invention
For the problem of above-mentioned existence, the purpose of this invention is to provide a kind of low temperature fusion process of waste and old wool.This method is to sneak into the low-melting fiber of 8%-15% in the wool aggregate of handling well, makes the adiabatic sound absorption material of suitable building field use by the method for compression and cutting.
The specific embodiment
Wool aggregate and low-melting fiber are 85: 15 according to weight ratio, mix.
Claims (1)
1. sneak into the low-melting fiber of 8%-15% in the wool aggregate, make the adiabatic sound absorption material of suitable building field use by the method for compression and cutting.
