Description
Technical field
The present invention relates to flame-retardant formulations field more particularly to a kind of flame-retardant formulations and its system of Polypropylene flame-retardant plastic template
Make method.
Background technique
The Chinese scale of capital construction is huge, consumes 10,000,000,000 Wood construction formworks year, as Environmental Protection in China pressure adds these years
Greatly, plastic formwork starts to rise, and especially pp hollow plastic formwork starts, and state's Curtain Wall is formd far to send out leading
Plastic formwork manufacturer start to expand on a large scale.The basic material of hollow plastic formwork is copolymer polypropylene, and talcum powder is to fill out
Fill the plastic building template of material, it is fire-retardant extremely difficult containing polyethylene component in Polypropylene copolymer material, and talcum powder material
Material and fire retardant cannot form synergistic effect.Therefore the fire-retardant of market plastic building template becomes extremely difficult or fire-retardant matches
Fang Chengben is very high, and properties of product decline is larger after market can not receive or is fire-retardant, and makes in production process because unstable
Cost is caused to further increase at process costs increase, so polypropylene is the fire-retardant problem of the plastic building template of main material
Become an extremely difficult problem.
Summary of the invention
The purpose of the present invention is to solve the fire-retardant extremely difficult of polypropylene plastics building template exists in the prior art,
Flame-retardant formulations cost is very high, and market can not receive, and fire-retardant rear properties of product decline is larger, and because unstable in production process,
The shortcomings that process costs increase, and cost is caused to further increase, and a kind of the fire-retardant of Polypropylene flame-retardant plastic template proposed is matched
Side and its manufacturing method.
A kind of flame-retardant formulations of Polypropylene flame-retardant plastic template proposed by the present invention, the raw material including following parts by weight: poly-
100 parts of propylene, 25-50 parts of filler, 2-8 parts of auxiliary addition agent, 0.6-4 parts of antimony oxide, Tripolycyanamide hydrobromide 1-4
Part, 2-10 parts of haloflex, 10-20 parts of mica powder.
Preferably, polypropylene series hollow plastic formwork is sold in market, and the product for doing flame-retardancy requirements uses this formula, fire-retardant
Function admirable relative inexpensiveness, and to product, other Effect on Mechanical Properties are minimum.
Preferably, the antimony oxide, Tripolycyanamide hydrobromide, haloflex, mica powder are market sale
Material, antimony oxide, Tripolycyanamide hydrobromide, haloflex, mica powder are synergy fire retardant between each other
Ingredient.
Preferably, the mica Powder Particle Size selects 400-1250 mesh.
Preferably, the filler is the mixing of talcum powder and mica powder mixture or talcum powder, calcium powder and mica powder
Object.
The invention also provides a kind of manufacturing methods of the flame-retardant formulations of Polypropylene flame-retardant plastic template, including following step
It is rapid:
S1: by polypropylene, filler, auxiliary addition agent, antimony oxide, Tripolycyanamide hydrobromide, haloflex, mica powder
It mixes in proportion；
S2: being granulated, and then plate is made in upper extruder molding, eliminates the process procedure that traditional approach makes master batch, reduces
Process costs dispense the carrier component for doing the low melting point in fire-retardant master granule, reduce tradition resistance in plastic formwork manufacturing process
Fire influence of the master batch emphasis low melting point carrier to template forming stability.
The beneficial effects of the present invention are: using conventional antimony oxide as basic fire proofing, melamine material is used
Material as organic fire-retardant as cooperative flame retardant, at high temperature, not only played it is fire-retardant after the fire retardant effect of polypropylene material, but also
Polypropylene material can be promoted quickly to drip and take away the temperature that a large amount of heat further decreases burning surface, use haloflex
Hydrogen chloride gas is decomposed to give off rapidly, further cooperates with antimony oxide fire-retardant；Further make full use of the increasing of haloflex
Tough effect, and utilized high temperature to decompose hydrogen chloride rapidly and achieved the effect that fire-retardant, synchronous strong using mica powder covering effect, product
The good advantage of tensile property, further collaboration is in this flame-retardant formulations system, at low cost, good flame retardation effect；
After meeting flame-retardancy requirements the present invention overcomes polypropylene plastics building template, other mechanical property sharp falls are asked
Topic, manufacturing process are further simplified, and stability of the production process is higher, reduces process costs, product tenable environment ability is strong, material
Expect at low cost, substantially meet flame-retardancy requirements, meet site safety requirement, is particularly suitable for plastic building template, to integral material
It can be promoted beneficial.
