Description
Technical field
The invention belongs to polymeric material field, and in particular to a kind of imitative ceramic flame-proof PBT/PC resin combinations and its system
Preparation Method.
Background technology
The ceramic used in daily life, it is that the mixture by clay or containing clay makees pug mixing mostly, passes through
Helical vacuum extruder is molded, and cuts into mud embryo and then calcining forms.Ceramic is natural, attractive in appearance, durable, inexpensive etc. with its
Feature, it is loved by people, is seen everywhere in life.But ceramics there is also firing high energy consumption, poor toughness is frangible the shortcomings of,
And manufacturing process needs valuable soil resource of using up, and also to consume the substantial amounts of energy, produces substantial amounts of discarded object,
Destroy natural, ecological.
, therefore, how will processing and plastic products have the advantages that light, good toughness, convenient formation, are easily recycled
Performance more excellent plastics copy ceramics, are always the direction that people make great efforts.Such as toner can is added in the plastic
Plastic material outward appearance is adjusted to various ceramic outward appearances, or realizes that plastics imitate the effect of ceramics by technologies such as surface lacquers, but
These measures are only the change of plastic products outward appearance, but without ceramic is thick and heavy, damage resistant, it is weather-proof etc. the advantages of.
The B of Chinese patent CN 101608055 disclose a kind of imitated ceramic plastic material, take in poly terephthalic acid fourth two
The method of the substantial amounts of barium sulfate of addition realizes the purpose for imitating ceramics in alcohol ester plastics (PBT).The shortcomings that this method is that it is terrible
To the density of similar ceramics, up to 71% barium sulfate is filled with plastic material.And the characteristics of due to barium sulfate itself, this
Sample, which is done, not only easily makes plastic material become difficult processing, and easily causes plastic material shock resistance to decline, the system made
Product are easily broken.And Chinese patent CN102321363 B disclose one kind and used based on polyamide and zinc oxide, iron powder is as increasing
The imitative ceramic product of heavy material, although this method can obtain the heavier imitative ceramic product of quality, because polyamide is poor
Weatherability, the weather resistance of this product can be caused poor far beyond ceramic product, not a kind of really imitative ceramic product.
Therefore, in the exploitation of imitative ceramic product, the apparent high glaze for reaching ceramics is not only wanted, in density and weatherability side
Face is required for reaching the level close to ceramics, and far above ceramics in terms of toughness, it is convenient to prepare, and so can be only achieved replacement
The purpose of ceramics.
