Description
Technical field
A kind of the radiation polycondensation melamine resin material and preparation method of the filling of high solid waste, by 1%-4% melamine resin and
The inorganics filled material of 99%-96% forms.Material waterproofing, the non-ignitable flexural strength with 15MPa or more, 2GPa-5GPa
Elasticity modulus, can continuous extrusion.Efficiently use Industrial Solid Waste.Product has cost and environment-friendly advantage.
Background technique
Inorganic filler ratio is increased to improve intensity and elasticity modulus, reduce the hot spot technology that production cost is plastic applications.
Such as PVC industry increases strength reduction cost as filler using calcium carbonate, flyash and passes through to formula, stuffing surface modification, technique
It improves and the additive amount of equipment improvement filler material is continuously improved to 80% or more.But incident plasticizing is difficult, and equipment is quick
The problems such as abrasion and additive toxicity, while intensity and elasticity modulus also offset from demand section, gradually lose using valence
Value.Therefore Polymer Industry inorganic filler be more than 90% it is very rare.Melamine resin has excellent intensity, water-fast, resistance to
It waits, non-ignitable performance, the materials such as excellent colloid, foam can be prepared by the modification such as phenol, alcohol.Powder melamine resin and cellulose
Fiber and a small amount of inorganic filler can be pressed into exquisite articles.But inorganic fill is greater than 90% and still keeps going back for good strength
It did not saw.Having in Industrial Solid Waste much has hydration activity, dissolves in water and the material that recrystallizes but in macromolecule material
Material field is all ignored, or is not utilized, and traces it to its cause and is difficult to introduce water during thermoplastic material plasticizing forming
Composition, although thermosetting plastics can introduce water composition acidity polycondensation reaction condition and most hydration reactions needed for weak base
Property condition be difficult to coordinate and the compositions such as curing agent, regulator seriously affect the hydration reaction of inorganic material, and it is uncontrollable, very
Difficulty accomplishes that polycondensation reaction is synchronous with hydration reaction.Filler is needed in order to reach 15MPa or more intensity and 2GPa-5GPa elasticity modulus
It forms complete aquation crystalline solid and forms ideal three-dimensional structure with the complete melamine resin condensation polymer interted, and this difference
Step causes the crystallization of filler aquation to be crystallized body blocking by resinite blocking or polycondensation, can not form complete structure.This difference
The trouble and be fatal to the destruction of intensity that step manufactures, therefore conventional method is unable to get the system of this structural integrity,
It is all often failure in experiment.
Summary of the invention
With the radiation device of controllable radiation power, realization is controllable without curing agent melamine resin polycondensation reaction, and can follow
The hydration reaction of filler forms synchronization, to obtain aquation crystalline solid and intert complete melamine resin condensation polymer and formed preferably
Three-dimensional structure is the core of the technical program.
The melamine resin synthesis that calcium hydroxide solution adjusts agent is had studied, 100 seconds sides to 100 millisecond periods are had studied
The radiant power output that wave, triangular wave, biradial pipe sine wave control.Have studied 2450MHz, 900MHZ microwave and 780nm-
The near-infrared light waves of 3um wavelength can obtain ideal three-dimensional structure.Have studied steel mill's grain slag, clinker, flyash, gangue,
Desulphurization, carbide slag, solid waste gypsum, the hydration reaction of silicon ash and fraction compositions aquation synchronous reaction, it is determined that 15W/
The radiant power domain of Kg-1.5KW/Kg.Have studied influence of the melamine resin to above-mentioned filler aquation and to integral material object
Manage Index Influence, it is determined that melamine resin total amount accounting can obtain physical index in 1%-4% and economic indicator is all ideal
Material.Have studied the preceding basic demand to idiosome of radiation: it must be the mixture of raw materials of well dispersed homogeneous, and total Body Water is answered
Meet filler hydration reaction demand, and idiosome flatness, finish, shape have to comply with requirement, parallel double-screw has been selected to squeeze
Machine completes mixing plasticizing out, and screw slenderness ratio is in 32:1 or more, and there are two the above fluxing zones, have obtained ideal mixing
Material, squeezes out to have obtained the idiosome for meeting basic demand through die orifice.Before irradiating raw material be finely dispersed water, it is melamine resin, inorganic
Filler, via radiation, dehydration, to have obtained filler hydration reaction after curing complete, the well-crystallized and normal filler aquation of overlap joint is anti-
Ying Tiyu polycondensation is complete, overlaps the three-dimensional structure that normal melamine resin intersects to form.It realizes 90% or more inorganic filler and protects
The melamine resin contracting of the high solid waste filling of 15Mp or more the flexural strength and 2GPa-5GPa elasticity modulus that stay thermosetting plastics just to have
Poly- material.Since Lauxite, phenolic resin have similar reaction mechanism but consider the invertibity and phenolic resin of pollopas
