Description
Technical field
The present invention relates to a kind of artificial quartz stone plate and preparation method thereof, more particularly to a kind of fire retardant man-made quartz slate
Material and preparation method thereof.
Background technology
Artificial stone is a kind of "dead", pollution-free, repeatable utilization, the architecture indoor novel decorative material of environmental protection
Material.As a kind of strategic novel healthy environment protection product for meeting national sustainable development, domestic city is introduced the eighties in last century
.The artificial stone sold in the market is main using macromolecule resin material as the organic type artificial stone of adhesive, is divided into three
Class：Artificial marble (hereinafter referred to as artificial hilllock stone), artificial quartz in lump and acrylic.Although China artificial stone industry starting compared with
Evening, but by the fast development of more than ten years, it is at the forefront in the world in terms of market scale and application popularization rate.
Artificial quartz in lump is natural with silicate (class) with unsaturated polyester resin or thermoplastic polyester as matrix
The inorganic material such as quartz and/or powder, silica sand, mine tailings (its main component is silica) is main stuffing, through specific
The artificial stone with certain specification size and dimension that technique is processed.Because its quality hard (Mohs' hardness 5-7), structure are caused
It is close, with the incomparable characteristic such as wear-resisting, pressure-resistant, anticorrosive, impermeable of other ornament materials.Artificial quartz in lump extensive use
In kitchen table top, laboratory table top, windowsill, bar desk, lift port, ground, metope etc..Building the field higher to material requirements
Institute's artificial quartz in lump is also all suitable for.
Halogen-free flame retardants, such as magnesium hydroxide, aluminium hydroxide are not only cheap but also fire proofing burning is not produced very
Many smog, releaser is mainly water and carbon dioxide etc. and the material of very major injury will not be caused to environment, so belonging to green ring
Guarantor's type product.But because halogen-free flame retardants is very poor with the compatibility of thermoplastic resin, dispersion is not easy in resin, even if point
Dissipate, affinity is also bad.Most domestic enterprise using coupling agent method, plastic powder, magnesium hydroxide or aluminium hydrate powder,
Coupling agent and other additives directly mix, but in the presence of dispersion be difficult uniformly, flame retarding efficiency it is low, need compared with disadvantages such as high filler loading capacities
Disease.To improve coupling degree, there are the flame retardant of magnesium hydroxide using atomization process processing of dusting in foreign countries, and performance is preferable, but raw
Produce apparatus and process more complicated.
