Description

The man-made stone corner stitch
Affiliated technical field:
The present invention relates to a kind of corner stitch and production technology, especially belong to corner stitch factory formula and the production technology of man-made stone as basal plane.
Background technology:
In recent years, flourish along with house property industry, adnornment industry, building materials industry, people constantly increase the demand of constructional materials, with the unsaturated polyester resin be primary raw material artificial hard stone product in the application in each field more and more widely, this kind material is replacing traditional plank, pottery, stone material and plastics etc.And do not have the man-made stone of sale corner stitch in the market, the corner stitch of being sold is a raw material with polyvinyl chloride (PVC) all, through extrusion modlings such as machine die equipment.Shortcoming is: product specification is low, can't varying sized size after the moulding, and surperficial pattern dullness, easily aging, hollow is fragile and can't repair.
Summary of the invention:
The purpose of this invention is to provide that a kind of designs and varieties are many, intensity good, processing and man-made stone corner stitch and production technology easy to use.Man-made stone corner stitch of the present invention comprises the corner stitch body of main part and the edge-pressing strip of supporting part, and the corner stitch body comprises outer corner stitch body and inside lock line body, it is characterized in that edge-pressing strip and corner stitch body are fixedly connected to form man-made stone corner stitch of the present invention.Described edge-pressing strip adopts T shape edge-pressing strip or class T shape edge-pressing strip or L shaped edge-pressing strip or L like shape edge-pressing strip; Adopt in the prescription of described man-made stone corner stitch:
1, unsaturated polyester resin can adopt any one of artificial marble resin, universal unsaturated polyester, photostability unsaturated polyester, chemical resistance unsaturated polyester, self-extinguishment unsaturated polyester.As the artificial marble resin, the gel of this resin and to solidify be the cross-linking process of long chain type unsaturated polyester ester molecule and unsaturated monomer, this crosslinked be under the effect of curing compound and accelerator, to carry out.This resin can be regulated thick rare with styrene or other thinner.Content is 22~70%, preferred 40%.
2, filler adopts the mixture of graininess or fleut or graininess and fleut, and almost any epipastic mineral all can be used as filler.But we are normally used to be calcium carbonate, aluminium hydroxide, marble dust, quartz powder, glass microballoon, French chalk and artificial imitative stone granulate or particulate.Granularity is between 0.015~80 micron, and content is 28~74%, and preferred 57%.3, accelerator, the organic acid of the transition metal-type of selecting for use (for example cobalt, manganese organic acid (ROO (CoMn))) impels activated curing agent, accelerated decomposition to become free radical with amine (for example dimethylaniline (CH3C6H6NH2)) accelerator easily, quicken the carrying out of cross-linking reaction, content is 0.5~1.5%, preferred 1%.4, select the organic peroxide curing compound for use, organic peroxide can decompose free radical, causes cross-linking reaction, methyl ethyl ketone peroxide for example, and content is 0.5~1.5%, preferred 1%.5, mill base, pigment make product have abundant colors, but must notice that some pigment has acceleration or slows down effect reaction, and content is 0.1~2%, and preferred 0.5%.
The composition and the content of man-made stone corner stitch of the present invention following (percentage by weight):
Unsaturated polyester resin 22~70%;
Filler 28~74%;
Curing compound 0.2~1.5%:
Accelerator 0.2~1.5%;
Pigment 0.1~2%.
Wherein:
1, unsaturated polyester resin adopts a kind of of artificial marble resin, universal unsaturated polyester, photostability unsaturated polyester, chemical resistance unsaturated polyester, self-extinguishment unsaturated polyester, is specially:
(1) universal unsaturated polyester is as adjacent benzene type unsaturated polyester, metaphenylene unsaturated polyester;
(2) photostability unsaturated polyester;
(3) chemical resistance unsaturated polyester is as M-phthalic acid type unsaturated polyester, bisphenol A-type unsaturated polyester, bisphenol-A and terephthalic acid (TPA) blending type unsaturated polyester;
(4) self-extinguishment unsaturated polyester.
2, filler adopts the powder body inorganic material of granularity between 0.015~80 micron, has at least a kind of preferably from calcium carbonate, aluminium hydroxide, marble dust, quartz powder, glass microballoon, French chalk and artificial imitative stone granulate or particulate.
3, accelerator is selected the organic acid and the amine of transition metal class for use, has at least a kind of preferably from cobalt, manganese organic acid (ROO (CoMn)), dimethylaniline (CH3C6H6NH2).
4, curing compound is selected organic peroxide for use, have at least a kind of preferably from ketone peroxide (R-O-OR '), hydroperoxides (R-O-OH), as methyl ethyl ketone peroxide, cyclohexanone peroxide (MEKP).
5, mill base, select for use organic and inorganic mill base all can reach must decorative effect, have a kind of preferred autoxidation titanium (TiO), zinc oxide (ZnO) at least.
The composition and the preferred content of man-made stone corner stitch of the present invention following (percentage by weight):
Unsaturated polyester resin 40%;
Filler 57%;
Curing compound 1%;
Accelerator 1%;
Pigment 1%.
The production technology of man-made stone corner stitch of the present invention has four kinds, and is specific as follows:
(1) normal temperature cure: unsaturated polyester resin, filler, accelerator, pigment are mixed, add curing compound and stir evenly again; Pour in the mould, the wedge pressure edge strip, normal temperature and pressure solidifies bonding, the demoulding, and dried man-made stone curved surfaces pastes hinge, packing.
(2) vacuumize heating cure: unsaturated polyester resin, filler, accelerator, pigment are mixed, add curing compound and stir evenly again; Pour in the mould, the wedge pressure edge strip is placed on vacuum P then and is generally 1 * 10 4Pa~3 * 10 4It is bonding to vacuumize curing in the vacuum tank between the Pa, and heating-up temperature is generally between 40 ℃~80 ℃.The purpose that vacuumizes and heat is to improve curing rate.The demoulding, dried man-made stone curved surfaces paste hinge, packing.
(3) each unsaturated polyester resin, filler, accelerator, the pigment with formulation content mixes, and adds curing compound and stirs evenly; Pour in the mould, normal temperature and pressure curing is bonding, the demoulding becomes the corner stitch body, and the corner stitch body is bonded into product with edge-pressing strip again.
(4) each unsaturated polyester resin, filler, accelerator, the pigment with formulation content mixes, and adds curing compound and stirs evenly; Pour in the mould, be placed on then to vacuumize in the vacuum tank and solidify bondingly, heating-up temperature is that the demoulding becomes the corner stitch body between 40 ℃~80 ℃, then the right-angle side fluting of corner stitch body with the edge-pressing strip embedded groove in and the gluing product that is tightened to.
The soft mode that above-mentioned mould can be made with silica gel.
Above-mentioned gelling, hardening time mainly are subjected to the influence of accelerator and curing compound addition, and the addition of accelerator and curing compound changes with the variation of environment temperature, humidity, pressure.
Matching used edge-pressing strip can adopt the edge-pressing strip of the various moulding that materials such as aluminium alloys, hard PVC, glass fiber reinforced plastic make.
Compare with the corner stitch of selling on the existing market, the present invention has following characteristics and advantage: owing to adopting man-made stone and being solid, thereby product specification height, surface-brightening, designs and varieties are many, inside and outside corner stitch all can satisfy the construction requirement in various corners, then just can reach with common sand paper if want varying sized behind the finished product.Damage, scratch are repaired easily, fire protection flame retarding, anti-aging, shock resistance, nontoxic, "dead" environmental protection.Have simple in structure, intensity good, manufacturing process is simple, characteristics such as easy to use.
