Description
One, technical field
The present invention relates to a kind of preparation method of masterbatch, particularly relate to the preparation method of a kind of ABS (acrylonitrile-butadiene-styrene copolymer) plastic working with defoaming, dehumidifying and drying mother stock.
Two, background technology
ABS resin is to be formed by vinyl cyanide, divinyl and three kinds of monomer copolymerizations of vinylbenzene.ABS resin has rigidity, surface hardness and the height chemical stability of polyacrylonitrile concurrently, the good workability of polystyrene and glossiness, and the shock resistance of polyhutadiene, toughness and elasticity, be widely used in car industry and electric industry as universal thermoplastic engineering plastic.
The mechanical mechanics property of ABS plastic goods directly influences the ABS plastic Products Quality, and the factor that influences ABS plastic products machinery mechanical property comprises the control of product defect in the performance of ABS plastic starting material own and the ABS plastic product molding course of processing.
ABS plastic is a macromolecular material, and its goods processing normally prepares by melt extruding with last cooling forming.ABS plastic absorbs airborne moisture content easily, and these moisture content can be vaporized in the high temperature process process, makes the ABS plastic goods produce bubble and hole, causes the decline significantly of ABS plastic products machinery mechanical property.Usually in the processing,, mainly take before processing, to use the method for baking oven for heating baking dehumidifying in order to remove the moisture content in ABS plastic and other starting material.The method that adds heat abstraction moisture content, extra heating and dehumidification equipment need be acquired by plastic working enterprise, increases by one complete processing program and production human cost, consumes a large amount of electric energy, causes the comprehensive cost of ABS plastic goods to increase substantially.
The froth breaking dehumidifying masterbatch production technology that is used for polyolefin plastics, existing both at home and abroad patent documentation report.Because the singularity of the The Nomenclature Composition and Structure of Complexes of ABS resin is different with polyolefin plastics, the development difficulty of defoaming, dehumidifying and drying mother stock that is specifically designed to ABS plastic is bigger, and practical application is more rare.
Three, summary of the invention
The purpose of this invention is to provide a kind of energy elimination and absorb water vapor, the bubble that ABS plastic adds the generation in man-hour, can make ABS plastic before processing, avoid toasting the defoaming, dehumidifying and drying mother stock of drying and product properties raising.The present invention is achieved in that acrylonitrile-butadiene-styrene copolymer plastic working defoaming, dehumidifying and drying mother stock, it is characterized in that comprising following each component, in weight part: calcium oxide 70～83wt%, acrylonitrile-butadiene-styrene copolymer 5～20wt%, coupling agent 1～3wt%, lubrication dispersing agent 2～8wt%, properties-correcting agent 2～10wt%.Described coupling agent is a kind of in titanate coupling agent, the aluminate coupling agent.Described lubrication dispersing agent is a kind of in calcium stearate, the Zinic stearas.Described properties-correcting agent is a kind of in atactic copolymerized polypropene, the terpolymer EP rubber.Its preparation method is made of following steps: 1, by high-speed stirring processing is carried out coating the first time in the calcium oxide surface with lubrication dispersing agent and coupling agent in high-speed mixer; 2, in high-speed mixer, under 100～120 degrees centigrade of high-speed stirring conditions, calcium oxide is carried out coating second time processing with properties-correcting agent; 3, the back coats processing with acrylonitrile-butadiene-styrene copolymer for the third time to calcium oxide; 4, compound joins in the pill tablets press through rubbing ball, granulation with the hands, sieving and make acrylonitrile-butadiene-styrene copolymer plastic working defoaming, dehumidifying and drying mother stock.
The present invention utilizes calcium oxide and water reaction can generate calcium hydroxide, and calcium hydroxide decomposition reaction can not take place when Celsius more than 200 spend.Thereby utilize calcium oxide and the trace water in the ABS plastic in the ABS defoaming, dehumidifying and drying mother stock to react the trace water of eliminating among the ABS.
In the ABS plastic course of processing, other starting material do not need through preheating the technology of dehumidifying in ABS plastic and the prescription, only need efficient defoaming, dehumidifying and drying master batch of the present invention and ABS plastic etc. are mixed together evenly, directly melt molding processing, in the course of processing, but the calcium oxide rapid absorption vaporization moisture content strong to moisture content absorption, and react with water, eliminate steam fast, avoid plastics to produce cavitation damages such as bubble, guarantee the degree of compactness of plastics and high mechanical mechanics property.Saved heating and dehumidification technology in the common plastic working process, reduced the investment of plastic working business equipment, reduced production human cost and power consumption, reduced the comprehensive production cost of plastics, for the plastic working industry provides a kind of new high-quality functional master batch product.
Preparation technology of the present invention is simple, and preparation process does not have the three wastes and produces.The ABS defoaming, dehumidifying and drying mother stock of the present invention's preparation can be used for the froth breaking dehumidifying of ABS plastic injection-molded item and extrusion moulding product.
The invention has the beneficial effects as follows:
1, saves labour turnover
The baking drying need increase formal personnel's input of producing before before traditional ABS plastic processing, and whole process of production need to continue artificial, and adopt the ABS plastic defoaming, dehumidifying and drying mother stock as long as simply can drop into processing after the mixing with the ABS plastic particle, do not need extra the input manually.
2, need not to increase roasting plant
The baking drying need be purchased roasting plant before traditional ABS plastic processing, and produces the equipment amortization expense, uses the ABS defoaming, dehumidifying and drying mother stock then not need other procuring equipment, does not have Abschreibungskosten.
3, save electric energy in a large number
The dry at least 120 degree electricity that need to consume per ton of baking use the ABS defoaming, dehumidifying and drying mother stock then not need additionally to increase power consumption before traditional ABS plastic processing.
4, reduce raw-material loss
The baking drying process moisture that can run off is generally 1～2% of weight before the processing of traditional ABS plastic, and uses the ABS defoaming, dehumidifying and drying mother stock to absorb total not loss of raw material weight behind the moisture content.
5, help cleaner production
Baking drying operation environment can produce noise and bisque pollution before traditional ABS plastic processing, thereby increases the labor insurance fees expenditure, uses the ABS defoaming, dehumidifying and drying mother stock then to make become between entire operation cleaning, health, few bisque.
6, enhance productivity
The baking drying equals to have increased drying process one before traditional ABS plastic processing, prolongs process period, and uses the ABS defoaming, dehumidifying and drying mother stock need not increase operation, saves process period, enhances productivity.
