Description
Technical field
The present invention relates to polymer composite, particularly polyblend tubing containing HPVC/SPVC/CPVC of a kind of fire retardant insulating for building and preparation method thereof.
Background technology
HPVC is the polychloroethylene with high polymerization degree resin that adopts dynamic vulcanization process to make, and its polymerization degree can reach 2000-2500, and this materials hot deformation temperature can reach more than 90 DEG C, but processing fluidity is poor.
SPVC is suspension pvc resin, and its polymerization degree is generally 800-1500, and this materials processing mobility and oil absorbency are better, but vicat softening temperature is lower.
CPVC is chlorinated polyvinyl chloride resin, and it has better flame retardant resistance and higher specific inductivity, but processing fluidity is poor.
What electrician's sleeve pipe for building was carried out at present is JG3050-1998 " insulating electrical casing pipe for building and accessory " building industry industry standard, has the index such as size, compressive property, bending property, resistance toheat, flame retardant properties of pair electrical casing pipe to make stipulations in this standard.Electrical casing pipe is in the market all that single-material is made substantially, more commonly PVC-U (rigid polyvinyl chloride) electrical casing pipe.PVC-U electrical casing pipe generally uses suspension method SPVC for basic material, adds the auxiliary agents such as a certain proportion of thermo-stabilizer, lubricant, toughner, weighting agent, after high-speed kneading, uses conical double screw extruder extrusion moulding.
Use single SPVC material produce electrical casing pipe, taking industry standard JG3050-1998 index of correlation as benchmark, usually attend to one thing and lose sight of another, such as having met bending property, compressive property etc. do not reach again, otherwise too.For meet the indices of JG3050-1998 simultaneously, use single SPVC material produce, need harsher fabrication process condition, weighting agent add-on is also limited in less scope, and manufacturing cost is higher.CPVC or HPVC are compared with SPVC, although there is multinomial performance more superior, but its processing fluidity is poor.Use single CPVC or HPVC forming materials difficulty, the products appearance of extruding is poor.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, polyblend tubing of the HPVC/SPVC/CPVC of the fire retardant insulating for building of the indices of a kind of JG3050-1998 of meeting and preparation method thereof is provided.

Described weighting agent is calcium carbonate, and described thermo-stabilizer is thiol methyl tin, and described toughner is acrylic elastomer, and described internal lubricant is Tegin 55G, and described external lubricant is polyethylene wax, and described tinting material is titanium dioxide.
A preparation method who contains the polyblend tubing of HPVC/SPVC/CPVC, comprises the following steps:
1) first take each component according to weight ratio.
2) mediate technique: SPVC, HPVC, CPVC, thermo-stabilizer, internal lubricant, external lubricant, toughner are dropped into successively and in high-speed mixer, is fully mixed into one-level compound; In the time that one-level mixture warm is raised to 110-120 DEG C, one-level compound is gone to low speed cold mixer, and add weighting agent and tinting material to be mixed into secondary compound; When secondary mixture warm drops to 40-50 DEG C in low speed cold mixer, secondary compound is emitted and is used container splendid attire.
3) extruding-out process: by the secondary compound conical double screw extruder extrusion moulding of splendid attire in container, the extruder temperature of extrusion is 50-60 DEG C, barrel temperature is 165-178 DEG C, and the rotating speed of conical double-screw is 35-50r/min, and die head temperature is 180-195 DEG C; After tube extrusion, after air cooling, enter water-cooled sizing tank and determined the outside dimension of tubing by calibration sleeve, the distance of air cooling is 30-50cm, the temperature 15-20 DEG C of water coolant; Tubing is driven and is moved ahead by tractor out from water-cooled sizing tank, and by regulating the speed of tractor crawler belt to control the wall thickness of tubing; After tubing cooling and shaping, after being cut into pieces and packing, be alloy pipe finished product.
The invention SPVC, HPVC are mixed mutually with CPVC, and according to the weight ratio of science, adopt the formula being formed by SPVC, HPVC, CPVC, weighting agent, thermo-stabilizer, toughner, internal lubricant, external lubricant, tinting material to prepare tubing, greatly improve shock resistance, ductility, flame retardant resistance and the insulativity of tubing, meet the requirements of the industry standard JG3050-1998 of electrician's sleeve pipe for building, technique is simple, and properties effect is splendid.
