Abstract
The invention relates to a weather-resistant ABS composition, a preparation method and application thereof, the composition comprises the following components: ABS resin, antioxidant, ultraviolet absorbent, light stabilizer and lubricant. The ABS material composition has higher color stability and higher ultraviolet aging resistance, and meets the use requirements of the household appliance industry on weather-resistant ABS materials.
Description
Technical Field
The invention belongs to the technical field of general plastics, and particularly relates to a weather-resistant ABS composition, and a preparation method and application thereof.
Background
ABS is a terpolymer of acrylonitrile, butadiene and styrene, has good mechanical property, surface gloss, oil resistance, chemical resistance and electrical property as engineering plastics with excellent comprehensive performance, has tough and hard mechanical property and good processability, can be directly injected and molded into products by extrusion molding, can be blended with other thermoplastic resins and engineering plastics or organic and inorganic fillers to prepare various composite materials, and is widely applied to the fields of household appliances, electronic and electric appliances, automobiles, machinery, buildings and the like.
However, the ABS resin contains a butadiene rubber phase, and unsaturated double bonds contained in the rubber phase are easy to be oxidized, degraded and yellowed under the action of light, heat, peroxide and the like, so that the mechanical property of the material is greatly reduced, and the application of the ABS resin is restricted. With the increasing improvement of the living standard of people and the increasing year by year of the export share of domestic appliances in China, various domestic appliance production enterprises put forward higher requirements on the color stability and the performance retention rate of plastic parts in the transportation and long-term use processes.
At present, almost all researches and patents are focused on how to improve the weather resistance of ABS and its alloy materials, and are mainly evaluated by methods such as laboratory accelerated aging (ultraviolet aging, xenon lamp aging, long-term thermal oxidation aging, darkroom aging) and the like, aiming at improving the yellowing resistance and performance attenuation resistance of high molecular materials under ultraviolet light, natural light, heat, water and other natural or artificial environmental conditions, but the researches on the aging phenomena of ABS and its products in indoor environment are very limited.
Researches show that the ABS resin and modified materials thereof, including flame-retardant ABS, weather-resistant ABS and the like, can generate color change reaction under indoor illumination conditions, such as indoor windowsill (avoiding direct illumination), indoor daylight lamps and lamp box (D65 light source), especially the color of a product or a sample plate after injection molding by an injection molding machine can shift towards the blue phase (blue change, the value of color b is reduced) within a certain time after molding, the color control and delivery of the molded product are seriously influenced, and in addition, the materials are yellowed along with the aging reaction.
Common technical research reports, papers and patents mainly focus on solving the problems of improvement and improvement of long-term weather resistance of materials, namely, the problems of material performance attenuation and color yellowing caused by oxygen, light, water and the like in the using process, but detailed reports and researches on the problem of color shift (blue shift) of products to blue phase in a short period after molding are not provided.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide the weather-resistant ABS composition and the preparation method and application thereof, and the obtained weather-resistant ABS has the characteristics of good short-term blue stain resistance and long-term yellowing resistance.
The invention relates to an ABS material composition, which comprises the following components in parts by weight:
wherein the average particle diameter of rubber in the ABS resin is more than 0.8 μm;
the ultraviolet absorbent is benzotriazole ultraviolet absorbent;
the light stabilizer is a polymeric hindered amine light stabilizer;
the lubricant is a weakly basic lubricant.
Preferably, the mass percentage of the butadiene rubber in the ABS resin is 10-25%, and the average particle size of the rubber is 1-1.5 μm.
Preferably, the antioxidant is one or more of phosphites, thioethers, hindered phenols.
Preferably, the phosphite is antioxidant 168; the thioether is DSTDP; the hindered phenol is antioxidant 1010.
Said benzeneThe triazole ultraviolet absorber is
Wherein R is halogen; r1 is C n H 2n+1 Wherein n is more than or equal to 3; r2 is H or alkyl.
Preferably, the benzotriazole ultraviolet light absorber is at least one of UV-327 and UV-326.
Preferably, the number average molecular weight of the polymeric hindered amine light stabilizer is 1000g/mol or more.
The polymeric light stabilizer has higher molecular weight, and has small speed and proportion of aggregation and precipitation to the surface of a product, and the probability of ions generated in the process of capturing free radicals is reduced, thereby reducing the formation of a polyurethane structure and the degree of blue stain.
Preferably, the weakly basic lubricant is at least one of zinc stearate and magnesium stearate.
Preferably, the mass ratio of the ultraviolet absorber to the light stabilizer is (3:7) to (7: 3).
The ultraviolet light absorber and the light stabilizer are in a preferred ratio range, and have better short-term blue-stain resistance and long-term yellow-stain resistance.
Preferably, the components comprise the following components in parts by weight:
the preparation method of the ABS material composition comprises the following steps:
weighing the components according to the weight ratio, shearing and mixing the ABS resin, the antioxidant, the ultraviolet absorbent, the light stabilizer, the lubricant, melting by adopting a double-screw extruder, extruding and granulating to obtain the ABS material composition.
The temperature of the double-screw extruder from a feed inlet to a die head is 180-210 ℃, the rotating speed of the double-screw extruder is 200-400 rpm, the pressure is 2-3 MPa, and the vacuum degree is lower than 0.1 MPa; the length-diameter ratio of the double-screw extruder is 36: 1-44: 1.
The invention relates to an application of the ABS material composition in an air conditioner panel.
The rubber particle size in the ABS resin is more than 0.8 mu m, the ABS resin has relatively larger rubber particle size, the larger the rubber particle is, the more the rubber content is, the less micromolecule residual monomers are dissociated in the SAN resin continuous phase under the same rubber content, and the later high-temperature forming and the action of thermal oxygen generate less active free radicals, so that the degree of performance attenuation of materials caused by oxidation reaction is reduced, and the ABS resin has higher color stability.
Experiments prove that the ABS resin can generate a blue-changing process, and the addition of the ultraviolet absorbent generally aggravates the blue-changing degree, probably because the ultraviolet absorbent can generate valence electron transition and release heat energy after absorbing ultraviolet light, so that heteroatom groups in the resin can generate more ions, and the formation of a polyurethane structure and the blue-changing degree are aggravated. In the invention, molecular acting forces of the benzotriazole ultraviolet absorbent with a specific molecular structure and the polymeric hindered amine light stabilizer are adopted, so that the degree of electron transition and ion generation after ultraviolet light absorption is further reduced, and the degree of blue-turning is reduced; the polymerization type hindered amine light stabilizer has higher molecular weight, and has small speed and proportion of aggregation and precipitation on the surface of a product, the probability of ions generated in the process of capturing free radicals is reduced, and further the formation of a polyurethane structure and the degree of blue change are reduced.
In addition, the weakly alkaline lubricants such as zinc stearate and magnesium stearate are added, and the dispersion of the ultraviolet absorbent can be greatly improved by virtue of the acid-base action force between the ultraviolet absorbent and the lubricants, so that better anti-aging and yellowing resistance performances are shown. If a lubricant with strong alkalinity (such as calcium stearate) and a small molecular weight hindered amine light stabilizer are selected, the lubricant, the stabilizer and the benzotriazole ultraviolet absorber react under the conditions of oxygen and water, and therefore poor thermal oxidation and wet and heat aging performance is shown, and certain influence is generated on the weather resistance of the material.
Advantageous effects
The ABS material composition has higher color stability, particularly has smaller degree of color deviation to blue phase under indoor illumination after injection molding, has higher ultraviolet aging resistance, and meets the use requirement of the household appliance industry on weather-resistant ABS materials.

As can be seen from comparative examples 3 and 4, the ABS system of the present invention has poor color stability and aging resistance only by using the ultraviolet absorber or light stabilizer, and the color stability and aging resistance are synergistically improved compared with those of example 1.
As can be seen from comparative example 6, the bluing degree was significant and the color stability was poor after the use of the low molecular weight light stabilizer 770DF, failing to achieve the effects of the present invention.
