Description

Corrosion-resistant, the functional green leather production method of resistance to deformation
Technical field
The present invention relates to field of leather, and in particular to a kind of corrosion-resistant, functional green leather production method of resistance to deformation.
Background technology
Leather industry is the traditional special advantage industry in China, is the pillar industry in China's light industry and Huimin Favorable to the people industry occupies indispensable status in national economy.In particular, 30 hair for many years since by reform and opening-up Exhibition, China has become the production center, trade centre and the Science & Technology Center of universally acknowledged world's leather, it is big to become world's leather State.
Although China is leather big country, but be not also leather power.Especially, though the environmental pollution of leather industry have it is larger The improvement and mitigation of degree, but still do not solve fundamentally.Distinct issues are still lime, sulfide, trivalent chromium, ammonia The pollutant of nitrogen, chlorion etc. is still eliminated far away, and the high problem of process hides solid waste containing chromium and wastewater discharge is still Unresolved, the maturity of resource technology is not high.According to statistics, China's leather industry waste water yield in 2014 is about 1.42m3, CODcr yields are about 42.71 ten thousand tons, and ammonia nitrogen yield is about 2.85 ten thousand tons.By administering, wastewater discharge is about 1.15 ten thousand Ton, 0.5%, the CODcr discharge capacitys for accounting for about national industrial wastewater discharge total amount are about 1.49 ten thousand tons, and ammonia nitrogen yield is about 3450 Ten thousand tons.Pollution in leather industry object is in addition to waste water, also a large amount of solid waste, in general, 1t ox-hides about generate the useless of 30~50m3 The solid waste such as the meat slag of water, the sludge of 150kg and about 400kg, skin slag, scurf.If not to the waste water of leather industry, given up Gas and solid waste is effectively treated, and is allowed to discharge, then will certainly cause strong influence to the health of environment and the mankind And threat.These problems have become the bottleneck for restricting development of China leather industry development.2014,《Process hides and fur manufacturing industry Wastewater discharge standard》(GB30486-2013) it issues and implements, higher want is proposed to environment and the ecological protection of leather industry It asks.And as the improvement of people's living standards, there is higher requirement to the corrosion resistance of leather shoes.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of corrosion-resistant, functional green leather production method of resistance to deformation, has Evil matter emissions are few, and have better corrosion-resistant, resistance to deformation leather production method performance.
To achieve the goals above, the present invention uses following technical scheme：A kind of corrosion-resistant, functional green skin of resistance to deformation Production method is removed from office, is included the following steps：It takes leather to pass through primary coat, tumbling, middle painting, fixed painting and rotary drum successively to handle up to leather Finished product, 1) primary coat described in is：According to mass fraction meter, 20~26 parts of nanometer grade silicas, 10~15 parts are changed under room temperature Property polysiloxanes aqueous lotion, 25-30 parts of anion polyurethane dispersion liquids sequentially add in 100-120 parts of deionized waters, heat up It to 30~40 DEG C, stirs evenly, with coating roller roller coating in scytoblastema surface, 20-25min is toasted at 80~90 DEG C, is down to naturally Room temperature, normal-temperature light is acrylic resin modified according to the lower nano-photocatalyst for being added 5~20 parts and 50~70 parts, and even application is in skin Remove from office surface, 70~80 DEG C of bakings；The grain size of the nanometer grade silica is 40~60nm；
