Description
Technical field
The invention discloses a kind of granolith, belongs to artificial stone's technical field.
Background technology
Natural granite is durable in use, is good construction material, but its exploitation and processing cost are higher, also contain in stone material
There is harmful radioactive element.In order to maximize favourable factors and minimize unfavourable ones, physical property have developed than natural granite more preferably, and surface " painting " has figure
The stonite of shape.
Granolith is using epoxy resin, curing agent, diluent etc. as binding agent, by varigrained natural flowers hilllock
The aggregate such as rock or river sand and filler are sufficiently mixed, are molded, solidifying a kind of advanced composite material (ACM) formed.Aggregate is granolith
One of chief component of material, its granularity selection ratio will have a direct impact to granolith performance.We are by aggregate
Particle diameter is divided into 8 grades, and particle diameter is in more than the 2.5mm coarse aggregate that is referred to as, referred to as fine aggregate of the particle diameter in below 2.5mm.Fine aggregate is made
With being filling coarse aggregate framework gap to ensure the compactness of granolith；Coarse aggregate act as combining to form with binding agent mixed
Coagulate native framework.Granolith material also needs to add appropriate filler in addition to above-mentioned aggregate, to improve granolith workability
Can, thermal coefficient of expansion and shrinkage factor, increase its mechanical strength and dimensional stability, with eliminate the moulding stress in solidification process,
Hole and crackle.Conventional filler has silica flour, Paris white, mica powder and talcum powder etc..Binding material mainly considers technology
Property, economy, to human body and environmentally friendly property etc., and with the optimization process time, the hardening that polymer viscosity is low, good,
The characteristics such as curing deformation is small and price is low.The composition of granolith 75%~80% is natural stone, the physical force of natural stone
Learn performance, granule size and its with compare granolith composite performance produce material impact, typically from granite,
The green stone of brightness and quartz etc., its chemical composition mainly has SiO2, CaO, MgO and Al2O3Deng.These rock surfaces and inside have
Many several micropores to hundreds of nanometers of diameter zero point, these micropores are gas and moisture enters and exits passage inside stone material, together
When gas and moisture also the materials such as acid-alkali salt are brought into and taken out of, make stone material more closely linked with working environment.
Artificial hilllock stone energy-conserving and environment-protective, without radioactive substance.Handsome in appearance, colour image is naturally uniform, compact structure is resistance to
Mill property is strong, resists and tears the features such as intensity is high, water absorption rate is low open, compensate for lithotome aberration, hole, crack, crackle, water absorption rate height etc.
Defect.But the tensile property of granolith is bad, therefore, also need further to study granolith.
