Description
Technical field
The invention belongs to building decoration area, more particularly to a kind of preparation method of light composite board.
Background technology
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.
Shortcoming one：Resin type artificial stone is using unsaturated polyester resin as cementing agent, because unsaturated polyester resin is
Liquid, other inorganic fillers are solid powder, are not easy to be well mixed during mixing, during mixing easy heat production cause resin solid in advance
Change, cause finished product sheet material material uneven, easily cracking, buckling deformation.
Shortcoming two：Resin type artificial stone is that resin demand is too big using unsaturated polyester resin as cementing agent, causes finished product
