Abstract

The invention discloses a formula of weather-resistant ABS (acrylonitrile-butadiene-styrene), which comprises ABS 121H, an antioxidant, an ultraviolet screener, an antiaging agent and an assistant, wherein the antioxidant is phosphite ester, the ultraviolet screener is phenyl salicylate, the antiaging agent is diphenolic propane, and the assistant is acrylonitrile. The weather-resistant ABS is prepared from the following components by percentage by weight: 98-99.66% of ABS 121H, 0.3-0.4% of phosphite ester, 0.01-0.5% of phenyl salicylate, 0.01-0.5% of diphenol propane and 0.02-0.6% of acrylonitrile. The weather-resistant ABS has the advantages of low temperature resistance, embrittling and cracking resistance, penetration resistance, aging resistance and sunlight resistance.

Description

A kind of prescription of weatherproof ABS

Technical field

The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of weatherproof ABS.

Background technology

ABS is the general thermoplastic engineering plastic that grows up 1940's; It is the very outstanding plastics variety of a comprehensive mechanical property; Not only have favorable rigidity, hardness and processing fluidity, and have the H.T. characteristics, can injection moulding, extrude or thermoforming.All with injection molding forming method processing, the advantage of ABS resin is impact-resistance, sound insulation property, scratch-resistant to most of trolley part, and thermotolerance is better, and is more attractive in appearance than PP, especially at horizontal impact-resistance and the comparatively strict parts of use temperature.ABS resin is to use in the automobile to be only second to Polyurethane and polyacrylic the third-largest resin.ABS resin can be used for Che Nei and car outer enclosure, widgets such as bearing circle, oil guide pipe and handle and button, radiator grill and lampshade etc. before the car outside comprises.ABS resin is processed easily; Finish size stability and surface luster are good; Easily application, painted can also be carried out metallize, plating, welding and suitability for secondary processing such as bonding, can be widely used in field of electronics; Comprise various offices and consumer electronics/electrical equipment, office electrical equipment comprises electronic data processing machine, office equipment.In electronic apparatus market, ABS resin will keep its status in requiring fire-retardant and high heat-stable electronics/electrical equipment market in recent years, fire-retardant and high heat-proof ABS resin with the competition of engineering plastic alloys such as ABS/PC in have remarkable advantages.ABS resin has in the daily necessities field widely to be used, and such as building materials tubing, sheet material or sheet material, has been replaced a part by the more cheap polyvinyl chloride resin of price in recent years.ABS resin is used for and the relevant field of building, and wherein extrusion sheet is used for sanitary apparatus such as bath box, swimming pool lining etc., the tubing of injection moulding and pipe fitting in addition, the produced in small quantities extrusion moulding Telephone cablePipeline.The AIE Asia-Pacific is international immediately following material market trend; Be devoted to the exploitation and the popularization of ABS material; Release a series of ABS automotive materials with excellent over-all properties and technology performance; The many new A BS matrix materials of exploitation place are like impact, flame retardant resistance, outward appearance, painted etc., for final user's use provides omnidistance support and helps and constantly provide new solution.

Summary of the invention

The object of the present invention is to provide low temperature resistant, the be full of cracks that prevents to become fragile, prevent to penetrate, prevent the prescription of a kind of weatherproof ABS of aging and anti-day light effect.

Technical scheme of the present invention is: a kind of prescription of weatherproof ABS, comprise ABS121H, oxidation inhibitor, ultraviolet screening agent, inhibitor and auxiliary agent, and said oxidation inhibitor is phosphorous acid ester; Ultraviolet screening agent is a salol, and inhibitor is a diphenylol propane, and auxiliary agent is a vinyl cyanide; Each composition weight proportion is that ABS121H accounts for 98%-99.66%, and phosphorous acid ester accounts for 0.3%-0.4%, and salol accounts for 0.01%-0.5%; Diphenylol propane accounts for, 0.01%-0.5%, vinyl cyanide 0.02%-0.6%.

In preferred embodiment of the present invention, said phosphorous acid ester comprise three monooctyl esters, three the last of the ten Heavenly stems ester, three (12 carbon alcohol) ester and three (16 carbon alcohol) esters etc.

In preferred embodiment of the present invention, each composition weight proportion of the prescription of said weatherproof ABS is that ABS121H accounts for 99%, and phosphorous acid ester accounts for 0.39%, and salol accounts for 0.16%, and diphenylol propane accounts for 0.16%, vinyl cyanide 0.29%.

The prescription of a kind of weatherproof ABS of the present invention has low temperature resistant, the be full of cracks that prevents to become fragile, prevents to penetrate, prevent the effect of aging and anti-daylight.

Embodiment

Below in conjunction with preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.

In one embodiment, a kind of prescription of weatherproof ABS comprises ABS121H, oxidation inhibitor, ultraviolet screening agent, inhibitor and auxiliary agent; Said oxidation inhibitor is phosphorous acid ester, and ultraviolet screening agent is a salol, and inhibitor is a diphenylol propane; Auxiliary agent is a vinyl cyanide, and each composition weight proportion is that ABS121H accounts for 98%-99.66%, and phosphorous acid ester accounts for 0.3%-0.4%; Salol accounts for 0.01%-0.5%, and diphenylol propane accounts for, 0.01%-0.5%; Vinyl cyanide 0.02%-0.6%, said phosphorous acid ester comprise three monooctyl esters, three the last of the ten Heavenly stems ester, three (12 carbon alcohol) ester and three (16 carbon alcohol) esters etc.

Further specify, sample test is to place 24 hours in the sample chamber, and the sample chamber temperature remains on 23 ℃, and relative humidity is under 50 ℃:
