Description
Technical field
The present invention relates to a kind of application process of shoemaking waste in construction material, more particularly to a kind of shoemaking waste is in stone
Application process in cream building materials.
Background technology
Shoe-making industry produces substantial amounts of leftover bits every year, mainly polyamine foamed plastic, polyester fiber, rubber, poly- second
The material of the organic high molecular compounds such as alkene, polypropylene, nylon, resin, wherein upper be mainly textile cloth (including cotton,
Acrylic fibers, polypropylene fibre, spandex, non-woven fabrics, compound wire side cloth etc.), leather (natural skin, artificial turf, synthetic leather skin etc.), rubber plastic
With other materials etc., light weight, density is small, and volume is big.
At present, this shoemaking waste does not utilize effectively also and method of disposal, not only soil, water body to stacking ground etc.
Ecological environment causes very big harm, and also there are huge fire hazard.Landfill disposal is such as used, not only to take a large amount of soils,
And be difficult degraded, also result in the waste of resource.Used as boiler oil, poison gas can be produced, environment is polluted, influences sky
Makings amount.Such as by useless fiber recovery or rubber, plastics regeneration, and there are quality is numerous and diverse, industrialized utilization is difficult and passes through
The problems such as help ineffective.Therefore, how feasible, reasonable in economy technical solution on selection technique, preferably handled
Have become urgent problem using these waste materials.
The content of the invention
The present invention provides a kind of preparation method of energy-conserving profit waste type gypsum block, and shoemaking waste is carried out surface modification,
The organic material in shoemaking waste is improved with the compatibility of gypsum inorganic material and with reference to power, and pass through different material reasonable group
Close and the gypsum block construction material with multiple performance is made in process optimization.
A kind of preparation method of energy-conserving profit waste type gypsum block, concretely comprises the following steps：
1）Shoemaking waste is broken into the waste granules of below 5mm；
2）By ratio of weight and the number of copies, by 5~8 parts of potassium methyl silicate, 0.5~2 part of aluminum sulfate, 0.1~0.3 part of VAE lotions,
Mixed liquor is made in 0.5~1 part of diatomite and 50~70 parts of water, is added in 1~5 part of above-mentioned waste granules, mix is equal
Drying for standby after even；
3）By step 2）Obtained waste granules and 1~4 part of cullet comminuted steel shot are added in building gypsum slurry, and gypsum is made
Building block；
In the above-mentioned methods, the shoemaking waste is the leftover bits that upper material produces, and is by containing cotton, acrylic fibers, polypropylene fibre, ammonia
The textile cloths such as synthetic fibre, non-woven fabrics, compound wire side cloth, the mixture of the composition such as leather and rubber plastic.
In the above-mentioned methods, the cullet comminuted steel shot is obtained by thermosetting property cullet steel through broken, can be used as a kind of super
Staple fiber, its size≤1mm, chemical composition are：10~21%SiO2, 0.5~3%Al2O3, 5~9%CaO, 0.3~0.8%Fe2O3、
0.6~1.2%Na2O, other is organic resin component.
In the above-mentioned methods, the potassium methyl silicate is commercially available technical grade, liquid, solid contents 30~40%.
In the above-mentioned methods, the aluminum sulfate is commercially available technical grade, effective content more than 98%.
In the above-mentioned methods, the VAE lotions are commercially available technical grade, and solid content is 50~58%.
The positive beneficial effect of the present invention：The present invention changes the pore surface of shoemaking upper waste material using chemical means
Property, form one layer of enhancement layer in its material surface, it is possible to increase organic material and the phase of gypsum inorganic material in shoemaking waste
Capacitive and with reference to power, can reduce the density of gypsum material, improve its cracking resistance and sound-absorbing effect, increase its heat-insulating property,
The energy-saving heat-insulating gypsum block with multiple functions can be prepared.Cullet comminuted steel shot can improve the toughness and cracking resistance of building block
Performance.The method of the present invention improves application of the shoemaking waste in building materials of gypsum, has opened up shoemaking waste and has safely and effectively utilized
New way, avoid the pollution to environment, reduce cost of disposal, realize the recycling of waste.
