Abstract
The invention discloses a fireproof and flame-retardant PVC tube. The fireproof and flame-retardant PVC tube is prepared from, by weight, 60-80 parts of PVC resin, 1-3 parts of montmorillonite, 1-2 parts of lubricant, 3-5 parts of inorganic flame retardant, 1-3 parts of heat stabilizer, 2-4 parts of filler and 6-10 parts of impact modifier. The prepared PVC tube has the advantages of being high in strength, good in flame retardance and the like.
Description
Technical field
The present invention relates to PVC material technical field, be specifically related to a kind of fire resistant flame retardant pvc pipe.
Background technology
PVC pipeline is the maximum plastic conduit of the market share, accounts for the share of plastic conduit nearly 70%.In recent years, China's PVC development is very fast, and annual growth rate reaches 8%, and the annual growth rate of demand 2%.In plastic pipe, PVC consumption holds a safe lead always, is widely used in water supply and sewerage pipeline.
Polyvinyl chloride resin inherently has high flame retardant, and pure polyvinyl chloride resin oxygen index reaches 24.5, can think a kind of material of excellent flame retardancy.But often add a large amount of auxiliary agents in order to improve Drawing abillity and pliability in its course of processing, and auxiliary agent is generally inflammable substance, a large amount of interpolations then reduce the flame retardant resistance of flexible PVC greatly.In addition, during PVC burning, raw smoke which is large, and interpolation is organic fire retardant mostly, not only poisonous, and easily causes secondary pollution.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of fire resistant flame retardant pvc pipe, and intensity is high, good flame resistance.
A kind of fire resistant flame retardant pvc pipe, is made up of the raw material of following parts by weight: be made up of the raw material of following parts by weight: polyvinyl chloride resin 60-80 part, polynite 1-3 part, lubricant 1-2 part, inorganic combustion inhibitor 3-5 part, thermo-stabilizer 1-3 part, weighting agent 2-4 part, impact modifier 6-10 part.
As a further improvement on the present invention, described polynite is nano imvite.
As a further improvement on the present invention, described inorganic combustion inhibitor is one or both combinations in antimonous oxide, magnesium hydroxide and aluminium hydroxide.
As a further improvement on the present invention, described thermo-stabilizer is rare-earth stearate and hydrotalcite.
As a further improvement on the present invention, described lubricant is stearin.
As a further improvement on the present invention, described impact modifier is MBS auxiliary agent.
Compared with prior art, tool of the present invention has the following advantages and beneficial effect: use inorganic combustion inhibitor, safety non-toxic, can not produce toxic gas; Polynite is a kind of very excellent char-forming agent, can improve Flame Retardancy; MBS auxiliary agent while increase PVC toughness, can not reduce again the resistance toheat of tubing; The use of rare-earth stearate and hydrotalcite, can improve the thermostability of PVC.
