Description
Technical field
The present invention is applied in architectural decoration, may be used as wallboard, floor, windowsill, cupboard, hearth plate etc.,
It is related to a kind of preparation method of sheet material.
Background technology
Material mine exploitation brings more than 70% barren rock material, handles these barren rock material or land occupation is stacked or filled out
Bury, damaged substantial amounts of valuable soil, rock material resource is become environmentally hazardous one big public hazards.Barren rock material is selected removes for these
A part of handicraft, colored stone sand grains are produced, the marble wastes of high whiteness are produced beyond some light powdered whitings, other equal nothings
Effectively or there is the method for economic value to utilize it.It is unbroken it is tens of in each mining area be seen everywhere colors stone riprap clinker into
Mountain Cheng Ling, fills up gully, and ruinate environment also easily forms mud-rock flow.
Artificial stone typically refers to artificial solid material, artificial stone quartz, artificial stone hilllock stone etc..Artificial stone type is not
Together, its composition is also not quite similar.Composition is mainly resin, aluminium powder, pigment and curing agent.Artificial stone is that " high polymer material polymerize
Body ", typically using unsaturated-resin and aluminium hydroxide inserts as main material, the technological forming such as agitated, cast, heating, polymerization
" macromolecule solid slab ", commonly referred to as：" resin plate artificial stone ".
Resin type artificial stone be using unsaturated polyester resin as cementing agent, with aluminium hydrate powder, natural marble rubble,
Quartz sand, calcite, stone flour or other inorganic fillers coordinate according to a certain percentage, and it is outer to add catalyst, curing agent, pigment etc.
The process such as agent, blended stirring, curing molding, demoulding drying, surface polishing is added to be process.However, present resin type people
Stone material is made to have as a drawback that：
