Description
Technical field
The invention belongs to polyvinyl chloride composite materials technical field, be specifically related to a kind of low halogen flame-proof PVC tube material, also relate to the preparation method of this pvc pipe material.
Background technology
Current polrvinyl chloride product occupies sizable ratio at building, traffic, electronic apparatus, family life daily necessities.As everyone knows. once polyvinyl chloride itself is fire-retardant and add while making soft or hard goods various interpolation auxiliary agents to make it not have flame retardant resistance to catch fire and will cause flame rapid spread and expand dense smog and poison gas, bring massive losses to fire fighting and people's lives and properties.Therefore, give superpolymer goods and become the task of top priority with flame retardant resistance.Many countries have worked out the various flame-retardant standards of macromolecular material. and regulation does not reach the goods of flame-retardant standard, and sales forbidden.
The standard that current fire-retardant spool is carried out is mainly state quality standard GB8624-2006.Fire-retardant spool can be divided into two types of the fire-retardant and halogen-free flameproofs of halogen, and wherein, although have, the fire-retardant addition of halogen is little, flame retardant properties is high, when its burning, can volatilize a large amount of poison gas, causes " secondary disaster ".The matrix of bittern-free flame-proof material is generally metal oxide, organometallics, hydration metal hydroxides etc., and fire retardant is the compound of magnesium hydroxide, aluminium hydroxide, antimonous oxide, molybdenum etc.If fire retardant formula is unreasonable, flame retardant effect is not ideal, if improve flame retardant properties by increasing addition, can improve again the cost and the bending performance that has affected material, the regulation that is difficult to be up to state standards of product.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of pvc pipe material with good flame-retardance energy and mechanical property is provided, this tube material can be able to well be applied in plastics fire-retardant and that electrical insulation capability requirement is high; The preparation method of this low halogen flame-proof PVC tube material is also provided simultaneously.
Above-mentioned purpose of the present invention is achieved by the following scheme:
A kind of low halogen flame-proof PVC tube material, described tube material is made up of the raw material of following weight parts: 80～120 parts of the polyvinyl chloride (PVC) RESINS that particle diameter is 0.1～0.2mm; Particle diameter is 20～40 parts, 300～500 object calcium carbonate; 5～15 parts of impact modifying agent ABS; 2～5 parts of sulfur-bearing organic tin salt thermo-stabilizers; 0.5～2 part of lubricant oxidation polyethylene wax; Particle diameter is 2～5 parts of 100～150 nanostructure modified aluminium hydroxides; Particle diameter is 1～3 part of the magnesium hydroxide of 1～10 micron; 0.5～2 part of auxiliary flame retardant.
Wherein, ABS is vinylbenzene (40%～50%), divinyl (25%～30%), vinyl cyanide (25%～30%) terpolymer, better to low-temperature impact modified effect.
Above-mentioned auxiliary flame retardant be zinc borate, zinc oxide, ferric oxide, red phosphorus, phosphoric acid salt, carbonate and organosilyl one or both.
For further improving flame retardant properties and the mechanical property of low halogen flame-proof PVC pipe, aforementioned tubes material is made up of the raw material of following weight parts: 100 parts of the polyvinyl chloride (PVC) RESINS that particle diameter is 0.1～0.2mm; Particle diameter is 30 parts, 300～500 object calcium carbonate; 10 parts of impact modifying agent ABS; 4 parts of sulfur-bearing organic tin salt thermo-stabilizers; 1 part of lubricant oxidation polyethylene wax; Particle diameter is 2～4 parts of 100～150 nanostructure modified aluminium hydroxides; Particle diameter is 1～2 part of the magnesium hydroxide of 1～10 micron; 0.5～1 part of auxiliary flame retardant.
The preparation method of a kind of low halogen flame-proof PVC tube material of the present invention is: calcium carbonate is added to polyvinyl chloride (PVC) RESINS high-speed mixing 2～5min; Add again other components mixed 20～30min of high speed heat at 120～135 ℃; Then stir blowing while being cooled to 40～60 ℃, be heated to extruding pipe material at 180～190 ℃.
Compared with prior art, the present invention has following beneficial effect: flame retardant properties is good, the Plastics Combustion performance test of carrying out according to GB2406-80, and oxygen index >40, meets safe handling requirement.Mechanical property meets the requirements, and after tested, the mechanical index such as the bending resistance of product, shock resistance, anti-pressure ability meet the requirement of GA305-2001.Preparation method's technique provided by the invention is simple, low production cost.
