Description
Technical field
The present invention relates to a kind of gabion net modified pellet of cladding special PVC.
Background technology
PVC was once a kind of plastics that yield is maximum in the world, owing to its production is simple, good insulating, flexibility are good, was therefore widely used in article of everyday use, artificial leather, tubing, electric wire etc..But due to its poor heat stability, the shortcoming such as mechanical property is bad, loss of properties on aging, cold tolerance are bad, and make it be applied in and be subject to a lot of restriction.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, it is provided that a kind of gabion net modified pellet of cladding special PVC, this pellet surface is smooth, and glossiness is high, has outstanding weatherability and splendid salt tolerant corrosivity；Adopt gabion net prepared by this pellet can meet the application requirement of the numerous areas such as traffic, water conservancy, municipal administration, water and soil conservation.
Present invention solves the technical problem that and have the technical scheme that a kind of gabion net modified pellet of cladding special PVC, it is characterized in that, be made up of the component of following weight portion: PVC resin powder 100 parts, liquid plasticizer 20 ~ 30 parts, auxiliary liquid plasticizer 5 ~ 10 parts, solid plasticizer 2 ~ 5 parts, heat stabilizer 1 ~ 3 part, 5 ~ 10 parts of antioxidant, in-lubricant 3 ~ 6 parts, external lubricant 1 ~ 3 part, modifier 0.5 ~ 1 part, reinforced modifier 5 ~ 10 parts.
Preferably, a kind of gabion net modified pellet of cladding special PVC, it is characterized in that, be made up of the component of following weight portion: PVC resin powder 100 parts, liquid plasticizer 23 ~ 28 parts, auxiliary liquid plasticizer 6 ~ 8 parts, solid plasticizer 3 ~ 4 parts, heat stabilizer 2 ~ 3 parts, 6 ~ 8 parts of antioxidant, in-lubricant 4 ~ 5 parts, external lubricant 2 ~ 3 parts, modifier 0.5 ~ 1 part, reinforced modifier 6 ~ 8 parts.
Preferably, described PVC resin powder is prepared by suspension method.
Preferably, described heat stabilizer is organo-tin het stabilizer.
Preferably, described antioxidant is phosphite ester.
Preferably, described in-lubricant is tristerin, and external lubricant is Tissuemat E.
Preferably, described modifier is modifier ACR.
A kind of preparation method of the gabion net modified pellet of cladding special PVC of the present invention, it is characterized in that, employing following methods prepares: first PVC resin powder, liquid plasticizer, auxiliary liquid plasticizer, solid plasticizer, heat stabilizer, antioxidant, in-lubricant, external lubricant, modifier and reinforced modifier is put in high-speed kneading machine by certain proportioning and mediates, then the powder blend mixed is added parallel double-screw extruder extruding pelletization.
A kind of gabion net modified pellet of cladding special PVC of the present invention illustrates as follows.
A kind of gabion net modified pellet of cladding special PVC of the present invention is to be primary raw material by suspension pvc resin powder, it is equipped with a small amount of liquid plasticizer, auxiliary liquid plasticizer, solid plasticizer, heat stabilizer, antioxidant, in-lubricant, external lubricant, modifier and reinforced modifier, through high-speed kneading, extrusion, make after cooling, in even-grained Powdered after formed product, the gabion net smooth surface prepared by this pellet, glossiness is high, there is outstanding weatherability and splendid salt tolerant corrosivity, fully meet the requirements that gabion net uses in the wild.
Suspension legal system PVC resin powder, oil absorption is good, and dry flow property is good, easily plastifies, and molding time is short, and process operation is convenient, and the PVC resin powder prepared is loose uniformly.
Heat stabilizer is organic tin stabilizer organo-tin het stabilizer, has the advantages such as efficient, excellent heat resistance, resistance to sulfide staining, can effectively delay the thermal degradation of PVC polymeric material, delay the heat ageing of PVC.
Antioxidant is phosphite ester, pollution-free, heat-resistant stability good, can delay the carrying out of PVC oxidizing process, thus stoping PVC aging and increasing the service life.
In-lubricant is tristerin, and external lubricant is Tissuemat E, in the PVC course of processing in-lubricant reduce melt viscosity, promote resin plasticizing, external lubricant slow down resin plasticizing, both with the use of, indispensable.
Modifier is modifier ACR, and the present invention adopts parallel double-screw extruder to process, and ACR auxiliary agent can reduce the slide wall of melt, is greatly improved the Shear heating usefulness in the course of processing, thus accelerates the plasticizing rate of pellet.
Compared with prior art, a kind of gabion net modified pellet of cladding special PVC of the present invention is had the beneficial effect that
A kind of gabion net modified pellet of cladding special PVC of the present invention can be widely applied to the fields such as traffic, water conservancy, municipal administration, water and soil conservation.The polyvinyl chloride resin that conventional formulation is made, poor heat stability, mechanical property is bad, loss of properties on aging, cold tolerance is bad, and the PVC pellet surface that inventive formulation is made is smooth, glossiness is high, there is outstanding weatherability and splendid salt tolerant corrosivity, fully meet the requirements that gabion net uses in the wild.
