Description
Technical field
The present invention relates to decorative materials technology, and in particular to a kind of marbling imitated and preparation method thereof.
Background technology
Artificial marble be earliest 20 century 70s in the U.S. occur, due to it have enough intensity, rigidity,
The performance such as water-fast, ageing-resistant, corrosion-resistant, can replace natural marble completely for various building decorations, and manufacture method is simple
It is single, with short production cycle, low cost, thus rapidly development is obtained in the U.S..It is each Europe, Asia and the world to be passed to progressively later
Ground, becomes a kind of construction material being widely adopted.
Artificial marble is such product to be commonly called as on domestic market, and Hong Kong ＆ Taiwan areas are referred to as seamless stone, external same
Class product is called Artificial Marble or Solid Surfacing Material, and its scientific name is that mineral-filled is high
Molecular composite material.
Briefly, artificial marble be it is a kind of by resin, mineral and pigment through vacuum casting or compression molding
Polymer composite.Wherein matrix resin accounts for the proportioning of 30-65%, because resin determines product most to a great extent
Whole performance, such as hardness, wearability, weatherability, antifouling property and mechanical strength etc., so the formula technique of resin is most important.
Existing artificial marble entity plane materiel its application surface very little, is currently limited to kitchen, defends table top use, and which is broader
Application need exploitation, particularly in special-shaped artificial marble top grade artware and artificial marble Wall or floor tile, family
The application in the fields such as tool fabric, is far from being developed.These products actually market capacity is huge, it is predicted that at least counting
More than hundred billion yuan.
Therefore invention one kind is marbling imitated has demand, with wide market prospect.

Percentage elongation is bigger.
2 crooked test of test case
It is determined that during test basis, adopting《The measure of plastics bending property》(GB/T9341-2008) and《Concrete mould
Plate plywood》Relevant regulations in (GBT17656 2008) are tested.
The bend test of this material adopts UTM-1422 universal testing machines.With sample support into simply supported beam,
Span centre is at the uniform velocity bent with 2mm/min, until stress is not further added by or reaches stopping test during 5% strain, is protected when sample is loaded
Card loading roll axis are vertical with the long axis centerline of sample.Sample is rectangular slab, is obtained by sampling machine, the concrete size of sample
For overall length 240.0mm, across footpath 200.0mm, width 20.0mm, thickness, 12.0mm.
After sample is obtained, 24h is placed in temperature (25 ± 2) DEG C, the standard environment of relative humidity (65 ± 5) %.
In obtained sample, each embodiment randomly selects five and is tested, and the outward appearance of check test sample is so as not to affect
The accuracy of result of the test.During sample fracture, result of the test of the fracture position beyond simply supported beam span centre 1/3 is cancelled, again with
Machine is chosen sample and is tested.23 DEG C of ambient temperature during test, relative humidity 63%.Anti-bending strength data are shown in Table 2.
