Abstract
The invention discloses a kind of preparation methods of the hollow bulky grain material of bivalve layer, using can water swelling resin as kernel, the most moisture of resin kernel elder generation pre-absorption, preparation is added with the hypostracum reinforced solution of a small amount of staple fiber, resin kernel for having been approached saturation absorbs, and web is formed in resin core surface, form hypostracum；Using balling technique, on surface, package can form the cementing material of intensity；After material hardening forms intensity, particle again passes by the solution containing penetration material with viscosity, and particle superficies is allowed to form a crust layer；It is conserved by the way of drying, releases the moisture of water-absorbing resin completely, form thermal curing, and formed hollow.The features such as prepared bivalve layer particulate material has good anti-dropping capability, has both specific strength height, and thermal and insulating performance is good, fire resistance is high, crack resistance is good.
Description
Technical field
The invention belongs to environmental treatments, building thermal insulation material field, it can also be used to agricultural ridging material, and in particular to a kind of
The preparation method of the hollow bulky grain material of bivalve layer.
Background technique
In recent years, as global water resources pollution is on the rise, biofilter obtains extensively in the technique of sewage treatment
Using.Haydite is a kind of shaggy porous mass as a kind of filtrate, and microorganism adhesion is good, has certain adsorption energy
Power is used widely in water process as biofilter material and matrix.
There is 103496866 B of patented product CN at present, disclosed hud typed unburned lightweight aggregate is as a kind of unburned pottery
Grain, has been applied, but this hud typed unburned lightweight aggregate toughness is poor in terms of building heat preservation, environmental treatment, in bulk
When with forklift be easily destroyed leak out EPS kernel；If, due to the presence of its kernel, particle overall porosity is lower, mistake as filtrate
Filter ability is inadequate.A kind of slug type light hollow haydite, uses the side of sintering disclosed in 102936127 A of patented product CN
EPS core removal in haydite is reached hollow by formula, but this mode energy consumption for preparing haydite is big, and haydite toughness is poor.
The beautiful China's research of the Huang of Liaoning building Professional School is prepared for a kind of more shell baking-free ceramicites, but this baking-free ceramicite density is larger,
Specific strength is lower, and porosity and water absorption rate are low, if filter capacity is insufficient as biofilter material.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of preparation method of the hollow bulky grain material of bivalve layer, prepared
The bivalve hollow bulky grain material of layer have that crack resistance is high, the high (intensity under unit intensity, i.e., identical close of light weight, specific strength
Under degree, intensity is high；Or under same intensity, density is low), good toughness, the characteristics such as thermal insulation property and fire resistance are good, in particle
Sky, porosity is higher, has good filter capacity.
Technical scheme is as follows:
A kind of preparation method of the hollow bulky grain material of bivalve layer, comprising the following steps:
Step 1) carries out pre- full water process to it using water absorbing resin particle as kernel, water extent control of satisfying 75~
90%；
Step 2) configures hypostracum reinforced solution, is placed in hypostracum for water saturated water-absorbing resin has been inhaled made from step 1)
In reinforced solution, stirring；
Step 3) selects portland cement sill or phosphate cement sill as cementing material, will be through step 2) place
The water-absorbing resin and cementing material of reason wrap up shelling using balling technique；
Step 4) carries out 1~4h of natural curing to the water-absorbing resin of step 3) package shelling obtained；
Step 5) configures outer shell reinforced solution, sprays the outer shell to the step 4) material surface obtained conserved
Reinforced solution；
Step 6) material that handles through step 5) is carried out it is closed, drying maintenance to get.
Preferably, the partial size for having inhaled water saturated water-absorbing resin is 2~7mm.
Preferably, the hypostracum reinforced solution is made of by weight percentage following raw material: 10~30% sodium metasilicate,
0.5~5% silicon dioxide powder, 5~30% industrial starch, 0.5~2% fibrous material, remaining is water.
Preferably, the fibrous material is polypropylene fibre, 2~3mm of length.
Preferably, the outer shell reinforced solution is made of by weight percentage following raw material: 5~20% sodium metasilicate, 0
~3% silicon dioxide powder, remaining is water.
Preferably, the temperature of step 6) the drying maintenance is 100~150 DEG C.
The present invention has the advantage that
(1) combustible material is free of, the fire resistance of aggregate is effectively increased as inner nuclear material using water-absorbing resin.It adopts
It with 100~150 DEG C of drying maintenance method, is on the one hand dehydrated water-absorbing resin kernel, to form hollow structure, reduces close
Degree；On the other hand, internal evaporation water can make Shell Materials form sufficient steam curing, be conducive to improve bulky grain
The specific strength of material.
(2) later period using the solution containing strengthening material as water-absorbing resin adsorbs liquid, and the ratio that aggregate can be improved is strong
Degree is conducive to aggregate early stage transport.
(3) aggregate premature brittle, easily rupturable feature can be obviously improved mixed with fiber in the strengthening material of hypostracum.
(4) outer layer also uses the solution containing strengthening material, and spraying particles or roller coating contain the solution of penetration material, allows particle
Surface forms a crust layer.
(5) kernel is resin, if because the presence of no oxygen, will not burn when high temperature, and melting as building thermal insulation material
When change, then absorption heat is needed to alleviate the rate of propagation of fire to reduce the spread speed of heat.
(6) porosity of the hollow bulky grain material of bivalve layer prepared by the present invention is big, and macroporosity can guarantee good heat preservation
Performance, for being remarkably improved the thermal insulation property of product in insulating product；The water absorption rate of material can also be effectively improved, is absorbed water
For rate through detecting up to 17% or more, drainage capacity is strong.
