Description
Technical field
The present invention relates to the modified-high polymer field, specifically refer to a kind of extrusion grade flame-retardant ACS resin and preparation method thereof.
Background technology
The PVC plastic door-window has the characteristics such as light weight, corrosion-resistant, high-strength, energy-saving sound insulation, easily processing and cost be low, at home popularization and application because of it.Composite co-extruding is one of Main Means of PVC section bar colorize, by being the color coextrusion material of 0.2mm～0.5mm in PVC Surface of profile co-extrusion a layer thickness, guarantees that product color is bright-coloured, aesthetic in appearance.Co-extrusion raw material commonly used has PVC, ASA and PMMA, but because the weather resistance of PVC itself is poor, thus more more options with ASA and PMMA as the co-extrusion raw material.
PMMA has good weather resistance and high tinctorial property, but because the poor mobile performance of PMMA, difficult at the uniform thin layer of PVC surface formation when producing, and PMMA is crisp, section bar collided with or during sawing otch easily cause the bulk crackle and collapse the angle, PMMA very easily absorbs water in addition, difficult oven dry before extruding, easily produce the defectives such as pit, cut at product surface, affect outward appearance and the performance of product.
The ASA resin has replaced the divinyl rubber in the ABS resin with not double bond containing esters of acrylic acid rubber, and when keeping ABS mechanical property, processing characteristics and tinctorial property, the ASA resin has more excellent weather resistance.For example the Chinese patent application of publication number CN101407617 discloses " a kind of high-performance extrusion grade ASA resin composition and manufacture method thereof ", this patent is by adding the auxiliary agents such as surface luster agent, lubricant, weather resisting agent, go out extrusion grade ASA resin composition through melting co-extrusion preparation, be used for and the PVC compound extruded.Though materials has excellent weathering resistance, price is higher, and cost performance is not outstanding, and because ASA does not possess flame retardant resistance, such as big fire, certainly will cause unnecessary loss.Fire-retardant ACS can address this problem preferably.The Chinese patent application of publication number CN101914260 then discloses " a kind of flame-retardant ACS resin and manufacture method thereof ", and the method can obtain the good flame-proof weather-resisting ACS resin of over-all properties by adding efficient bromine antimony compound flame retardant.But general Flame Retardant ACS melt strength is lower, easily breaks in the fusion drawn process, is difficult to satisfy the composite co-extruding processing request.
Summary of the invention
Technical problem to be solved by this invention be the present situation for prior art provide a kind of can with the extrusion grade flame-retardant ACS resin of PVC composite co-extruding.
Another technical problem to be solved by this invention provide a kind of can with the preparation method of the extrusion grade flame-retardant ACS resin of PVC composite co-extruding.
The present invention solves the problems of the technologies described above the technical scheme that adopts: this extrusion grade flame-retardant ACS resin is characterized in that comprising the following weight parts component:
Wherein, the weight-average molecular weight of described ACS resin is 200000～300000, rubber content 20～30wt%, melt temperature be 180～220 ℃;
It is 5000～15000 brominated epoxy resin and/or brominated polycarbonate oligopolymer that described bromide fire retardant is selected from molecular weight;
Described toughner is selected from CPE rubber and/or ASA high glue powder;

Described lubricant is stearic acid and/or polyethylene wax.
Described oxidation inhibitor be selected from oxidation inhibitor 245, TNPP, 215,225 and B900 at least a;
Described weather resisting agent is selected from least a among uv-absorbing agent UV-P, UV-327, UV-531, UV-770 and the UV-944;
Because fire retardant and ACS resin compatible are relatively poor, under flame retardant properties prerequisite up to standard, should reduce its consumption as far as possible.The present invention is on the basis of lot of experiments, fire retardant adopts bromide fire retardant and the superfine antimony trioxide compositional flame-retardant system with synergistic effect, reduce the usage quantity of fire retardant, reduced simultaneously fire retardant to the physical strength of ACS resin and the damage of surface luster.
Add simultaneously an amount of toughner and further improve the defective that ACS resin shock strength that fire retardant causes declines to a great extent, and by adjusting the consumption of toughner, can obtain the extrusion grade flame-retardant ACS resin of the different size such as rigidity, middle anti-impact, high-impact and purposes.
The use of compound heat stabilizer among the present invention, also given full play to the synergistic effect between calcium/zinc composite stabilizer and Lead salt thermal stabilizer, guarantee that the halogenation Hydrogen Energy that ACS resin and bromide fire retardant produce because of degraded is in time absorbed in the high temperature process process, avoided the series of problems such as color of resin variation, physical strength reduction, weathering resistance decline and mould corrosion that cause because of dehydrohalogenation.
The melt strength conditioning agent that adds among the present invention can significantly improve melt strength, enlarges process window, has improved the production capacity of co-extrusion unit; Simultaneously, extrude front easy oven dry, the product surface glossiness is good, the outward appearance of product and excellent property.The melt strength conditioning agent has multiple, calcium carbonate for example, and its conventional amount used is 5～10 parts/100 parts resins.The present inventor finds in test the inorganic powder such as calcium carbonate because thermal conductivity significantly is higher than plastics, easily cause ACS/PVC coextruded layer inside and ACS, PVC two-phase interface temperature to raise fast through high temperature irradiation, accelerated the degradation with aging of material, cause the aggravation of material surface variable color degree, and the inorganic powder such as calcium carbonate and ACS consistency are bad, process the improper decline that easily causes the every mechanical property of ACS.The present invention finds that ultra-high molecular weight ACR and/or ultra-high molecular weight SAN as the melt strength conditioning agent of ACS, can better solve general ACS melt strength defective on the low side on the basis of lot of experiments, and good with the ACS consistency, and addition is few.In addition, owing to substantially do not contain two keys in the molecular chain, little on the impact of ACS weather resistance.Ultra-high molecular weight ACR particularly, molecular chain includes the esters of acrylic acid group, based on the refractive power effect of esters of acrylic acid group, adds the proper surface luster that can further improve ACS.
The interpolation of lubricant has further improved the processing forming of flame-retardant ACS resin, has improved the surface gloss of flame-retardant ACS resin.
The adding of oxidation inhibitor then improves hot workability and the thermo oxidative aging stability of flame-retardant ACS resin, has guaranteed the work-ing life of goods, so that flame-retardant ACS resin life-time service out of doors.
Weather resisting agent then can provide outstanding light stabilising effect, helps to reduce aberration, delays simultaneously the rational loss of energy of yellowing and blocker, with oxidation inhibitor and with further improving the heat-resisting of goods, light aging resisting effect.
Drawn best mixture temperature and time of processing above-mentioned prescription, extruded processing temperature and screw speed through repetition test, the good distribution of fire retardant and the fully plasticizing of resin have effectively been guaranteed, avoid because of excessive temperature and cross strong shearing force and cause the resin degraded, guaranteed the mechanical property of resin and good outward appearance smooth finish.
