Abstract
The invention discloses a kind of flame-retardant polystyrene plastics, by weight, by following material composition：60 90 parts of polystyrene, 10 20 parts of polyisobutene co-polymer, 10 30 parts of phenol-formaldehyde resin modified, 10 20 parts of zinc oxide, 10 20 parts of calcium stearate, 5 10 parts of crosslinking agent.The flame-retardant polystyrene plastics of the present invention are added to the magnesium oxide modified phenolic resin of fire resisting modification in formula, so that drama vinyl plastics have certain fire resistance, in addition micron-sized zinc oxide is added in being formulated, zinc oxide is uniformly distributed in polystyrene and the crosslinked molecule of the skeleton of phenolic resin, enhances the fire resistance of polystyrene plastics.
Description
Technical field
The present invention relates to plastic applications, more particularly to a kind of flame-retardant polystyrene plastics.
Background technology
Polystyrene plastics has surface hard and smooth, and transparency is good, strong coloring force, and advantage bright in colour is answered extensively
For optical instrument and daily necessities, such as it is used for making agricultural greenhouse, film, tea tray, comb etc..Wherein, it is moulded using polystyrene
To the flame retardant property of polystyrene plastics, more stringent requirements are proposed when expecting ceiling as agricultural greenhouse, in order to avoid cause full wafer agriculture
The burning of sparetime university's canopy and cause huge economic losses.Currently, common fire retardant is fluorine-containing fire retardant, this based flame retardant only prolongs
The time of slow combustion, thus can be polluted when polystyrene plastics burns, larger wound is all brought to human body and surrounding enviroment
Evil.Thus, it develops a safe flame-proofed polystyrene plastics and is of great significance.
Invention content
The present invention solves the technical problem of：Existing flame-retardant polystyrene plastics easily cause two in burning
The problem of secondary pollution.
In order to solve the above technical problems, one aspect of the present invention is：The present invention provides a kind of flame retardant type polyphenyl
Vinyl plastics, by weight, by following material composition：60-90 parts of polystyrene, 10-20 parts of polyisobutene co-polymer, changes
10-30 parts of phenolic resin of property, 10-20 parts of zinc oxide, 10-20 parts of calcium stearate, 5-10 parts of crosslinking agent.
Preferably, the phenol-formaldehyde resin modified is metal oxide modified phenolic resin.
Preferably, the phenolic resin is magnesium oxide modified phenolic resin.
Preferably, the zinc oxide is micron order zinc oxide.
Preferably, the grain size of the zinc oxide is 10-50 microns.
Preferably, the crosslinking agent is silane coupling agent.
The beneficial effects of the invention are as follows：The flame-retardant polystyrene plastics of the present invention are added to fire resisting modification in formula
Magnesium oxide modified phenolic resin so that drama vinyl plastics have certain fire resistance, and micron order is added in being formulated in addition
Zinc oxide, zinc oxide is uniformly distributed in polystyrene and the crosslinked molecule of the skeleton of phenolic resin, enhances polystyrene modeling
The fire resistance of material.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
The flame-retardant polystyrene plastics of the present invention, by weight, by following material composition：Polystyrene 60-90
Part, 10-20 parts of polyisobutene co-polymer, 10-30 parts of phenol-formaldehyde resin modified, 10-20 parts of zinc oxide, 10-20 parts of calcium stearate,
5-10 parts of crosslinking agent.
Further, the phenol-formaldehyde resin modified is metal oxide modified phenolic resin.
Further, the phenolic resin is magnesium oxide modified phenolic resin.
Further, the zinc oxide is micron order zinc oxide.
Further, the grain size of the zinc oxide is 10-50 microns.
Further, the crosslinking agent is silane coupling agent.
For the content further illustrated the present invention, it is as shown in table 1 to enumerate embodiment.
The flame-retardant polystyrene flame retardant of plastic performance of the present invention is weighed by measuring oxygen index (OI) and smoke density grade
Amount, with reference to GB8924, the assay method of smoke density grade carries out the assay method of oxygen index (OI) according to GB 8627.
For the content further illustrated the present invention, it is as shown in table 1 now to enumerate embodiment：
1 embodiment 1-3 formula components tables of table
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to be said using the present invention
Equivalent structure or equivalent flow shift made by bright book content is applied directly or indirectly in other relevant technical fields,
Similarly it is included within the scope of the present invention.
