Abstract
The invention relates to a waste wool jute low-temperature melting method used for sound-absorption heat-insulation construction materials. Leftovers formed in the wool carding process of a wool spinning enterprise are used, and the slag of the leftovers is removed, and the leftovers are combed and 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 jute and low melting point fiber with the melting point of 110 Celsius degrees, and therefore the heat-insulation and sound-absorption materials applied to the construction material standard are manufactured through sizing and compressing procedures. The waste wool jute low-temperature melting method used for the sound-absorption heat-insulation construction materials is low in energy consumption and short in technical process.
Description
Technical field
The present invention relates to a kind of low temperature fusion method based on waste and old wool and jute, 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 are as primary raw material, and supporting by the arm appropriate jute can " turn waste into wealth ", reduces the waste of resource.But at present that the method energy consumption of wool and jute 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 the low temperature fusion process of a kind of waste and old wool and jute.This method is to sneak into the low-melting fiber of 8%-15% in the wool of handling well and jute aggregate, makes the adiabatic sound absorption material of suitable building field use by the method for compression and cutting.
The specific embodiment
The aggregate of wool, jute 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 aggregate of wool and jute, make the adiabatic sound absorption material of suitable building field use by the method for compression and cutting.
