Abstract
The invention discloses a PBT flame-retardant master batch. The PBT flame-retardant master batch comprises components by mass: 10%-15% of a PBT carrier, 50%-70% of a main flame retardant, 15%-35% of an auxiliary flame retardant, 1%-3% of a coupling agent, 3%-5% of a dispersant and 1%-2% of an antioxidant. The prepared master batch has the characteristics of high concentration, low cost and convenient use. Besides, by using the master batch in producing the PBT, a production process can be simplified; production efficiency is increased; dust flying is reduced; environment pollution is prevented; and clean production is facilitated. The master batch can be easily mixed with a PBT raw material uniformly; and mixing quality and performance indexes of the product can be further increased.
Description
Technical field
The present invention relates to a kind of fire-retardant master granule, specifically a kind of PBT fire-retardant master granule.
Background technology
Polybutylene terephthalate (PBT) is the linear saturated polyester resin of a kind of crystal type, owing to having good electric property, resistance toheat, fatigue performance, low-friction coefficient and lower-price characteristic, is widely used in the industries such as electronic apparatus, household electrical appliances, automotive industry, mechanical means, material of construction.Yet, because PBT easily burns, so it is flame-retardant modified conventionally need to add amount of retardant to carry out at production PBT, using the fire retardant overwhelming majority is at present powder, like this when mixing with PBT raw material, the utmost point is not easy to mix, and the dust of kicking up while mixing pollutes surrounding environment and unhealthful etc. especially, is unfavorable for cleaner production.
Summary of the invention
The object of the present invention is to provide a kind of high density, low cost, cleaner production and PBT fire-retardant master granule easy to use.
The technical solution adopted for the present invention to solve the technical problems is: a kind of PBT fire-retardant master granule, its component by mass percent proportioning is: PBT carrier 10%～15%, main flame retardant 50%～70%, auxiliary fire retardant 15%～35%, coupling agent 1%～3%, dispersion agent 3%～5%, oxidation inhibitor 1%～2%.
Described PBT carrier is polybutylene terephthalate.
Described main flame retardant is TDE, decabromodiphenyl oxide, tetra bromobisphenol A ether, poly-2,6-dibromo phenylene ether, tricresyl phosphate (2, the chloro-2-propyl group of 3-bis-) ester, 1, a kind of in two (tetrabromo phthalimide) ethane, three (2, the 4-dibromo phenyl) phosphoric acid ester of 2-, Wrapped up Phosphorus Fire Retardant.
Described auxiliary fire retardant is a kind of in antimonous oxide, aluminium hydroxide, magnesium hydroxide.
Described coupling agent is a kind of in silane coupling agent, titanate coupling agent, aluminate coupling agent and phosphate coupling agent.
Described dispersion agent is one or more the mixture in polyethylene wax, Poly Propylene Wax, EVA wax, OP wax, TAS-2A.
Described oxidation inhibitor is the compound of antioxidant 1076 and irgasfos 168.
The preparation method of above-mentioned a kind of PBT fire-retardant master granule, comprises the following steps:
(1) each component is weighed up stand-by by weight ratio;
(2) PBT carrier and main flame retardant, auxiliary fire retardant, coupling agent, dispersion agent, oxidation inhibitor are added in high-speed mixer, fully mix 3～5 minutes;
(3) said mixture added to twin screw extruder is extruded, after granulation, drying, pack and obtain a kind of PBT fire-retardant master granule.
Compared with prior art, the invention has the beneficial effects as follows, made master batch has high density, low cost and the feature such as easy to use, at production PBT, use this master batch can simplify production technique simultaneously, enhance productivity, can reduce dust from flying again, avoid environmental pollution, be conducive to cleaner production, and use this master batch easily to mix with PBT raw material, thereby further improve performance index of mixing and goods etc.
