Abstract
The produce method for two-color artificial marble comprises burdening, mixing, coloring, injecting mould, die casting, solidification, saw cutting and grinding; wherein, dividing the raw material composed of resin, filler, solidifying agent and addition agent into A and B constituents; adding separately basal body and grain colorant to mix; mixing the A and B constituents to inject, die casting and solidify that makes two kinds color material mixed with resin and not single mixed color. The product has grain and natural texture and fits to spread to improve existing device.
Description
Affiliated technical field
The present invention relates to a kind of production method of artificial marble, particularly a kind of production method of two-color artificial marble that has the decorative pattern texture with casting die production.
Background technology
At present, utilize thermosetting resin and metaling to produce artificial marble, the overwhelming majority adopts the casting die of Batch Process.The artificial marble of producing by casting die, all are one color product, the colouring agent that no matter adds (pigment) is one or more different colors, used raw material are after mixing and die casting, the famine material of institute's moulding obtains having only a kind of color, no matter be matrix or texture, all be with a kind of mixed color.Thereby these products can not manifest the native texture texture that " marble " peculiar the sort of cloud and mist curls up, cloud is elegant of the local Yunfu of picture special product.Nature, with regard to outward appearance, monochromatic artificial marble is difficult to compare favourably with natural marble or marble, thus its range of application is restricted.
Chinese invention patent application publication number CN1262645A discloses the international application file that 9980430.8 of application numbers are called " production method with artificial marble of candy strip ".Disclosed method is to adopt the liquid resin injection mould of different colours indoor, through being laminated into two-layer or multilayer, inserts in the middle of each layer with the pectination instrument before it solidifies, and pulls the pectination instrument, makes the colorant diffusion between each layer and infiltrates the formation floral designs.This method has adopted the complicated process units of a cover, particularly on the pectination instrument, designs the comb of various ways.This is higher to the requirement meeting of a whole set of process units after all; And resulting final products may not necessarily reach such texture of natural marble and texture.
Summary of the invention
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part, and provide a kind of equipment simple, can produce production method of two-color artificial marble with decorative pattern texture.
Purpose of the present invention can reach by following measure:
A kind of production method of two-color artificial marble comprises and will comprise synthetic resin, filler, colouring agent, the curing agent and the additive that comprise initator and crosslinking agent are prepared burden at material compound interior, that produce artificial marble, mix also painted, injection molding, die casting is solidified, and the waste material of obtained by molding is cut saw, polishing waits each operation, it is characterized in that
1. in mixed process, with described material compound is two components, and adopt different colouring agents respectively, mix respectively separately, in vigorous stirring in the agitator more than 15 minutes, wherein, as the deal of a kind of material compound B component of decorative pattern colorant, with ratio as the deal of the another kind of material compound A component of matrix colorant be the B component: A component=(5～10): 100;
2. above-mentioned A component and the B component after mixing respectively is mixed in the blend tank, at the rotating speed below 30 rev/mins, and slight again the stirring mixed 10 seconds～1 minute, or with manual mode mixing, injection molding then.
Above-mentioned material compound can be to comprise that one or more are selected from unsaturated polyester resin, the thermosetting resin of acrylate and methacrylate resin, one or more be selected from aluminium hydroxide, calcium carbonate, silicate, magnesia and marble chips stone and powder filler, one or more are selected from the initator of peroxide and perester compound, with the acrylate compounds as crosslinking agent, and one or more comprise the additive of ultra-violet absorber, fire retardant, releasing agent, fluidizing reagent, thickener, polymerization inhibitor, antioxidant.
Above-mentioned die casting operation is to apply pressure to the pressure of 2.5MPa～4.5MPa on the press on the mold.
The viscosity of above-mentioned material compound is at 1 pool～50 pools.
Above-mentioned curing process can be to place spontaneous curing at normal temperatures or heating 2 hours and solidify under 30 ℃～60 ℃ temperature atmosphere.
Production method of the present invention has following advantage:
1. utilize the existing device of producing monochromatic artificial marble, can produce two-color artificial marble with the decorative pattern texture that can match in excellence or beauty with natural marble.Separate by matrix colorant and decorative pattern colorant and to carry out fully mixedly separately, two kinds of colors just interpenetrate when treating die casting, have avoided two kinds of pigment mixed too early and form single secondary colour.The inventive method is the applicant through producing test and grope out the needs of complete realistic production for up to a hundred times one year over.And production equipment is simple.
2. the good product quality of gained.Have graceful floral designs in appearance, have natural texture on the quality, strength difference and the stress warpage due to reversing does not appear in even structure.
Below in conjunction with drawings and Examples the present invention is done further non-limiting narration.
Description of drawings
Fig. 1 is the technological process of production schematic diagram of the inventive method, wherein the code name of each operation is, mixing of 1 expression batching, 2 expression A components, mixing of 2 ' expression B component, two kinds of parts of 3 expressions are mixed, 4 expression injection moldings, 5 represent that die casting, 6 expressions are solidified, saw is cut in 7 expressions, 8 expressions are polished.
The specific embodiment
With 10 parts of viscosity unsaturated polyester resin that is cp, with 90 parts from 20 order to 80 purpose rubbles, the filler of forming with 100 order to 800 purpose stone flours etc., and 0.5% initator of weight resin and weight resin " 2% crosslinking agent; and according to the additive of corresponding requirements; place in the material-compound tank to mix, obtain the material compound that viscosity is cp.Total amount is divided into two components about 1.2T～2.0T (ton) with it, adds the colouring agent 1 as the matrix colorant in the wherein big component, becomes the A component; Add colouring agent 2 in the little component, become the B component as the decorative pattern colorant.Two components must be distinguished mixing fully, fiercely stir more than 15 minutes, lump together then, are gently mixing 10 seconds～1 minute with the low speed below 30 rev/mins in the mixing tank, or mixed with manual mode, that is are that they are mixed fully.
Above-mentioned mixed material compound is presented to 1.25 * a 2.45 * 0.2m
3Mold in, move on the press with the pressure die casting of 3MPa (MPa) 10 minutes, spontaneous curing then, perhaps heat 2 hours to quicken curing at 30 ℃～60 ℃, obtain the waste material of monoblock, cut saw and polishing more on request, obtain the two-color artificial marble that the inventive method is produced with texture and natural texture and outward appearance.
