Abstract
The present invention relates to a granular flame retardant master batch with high concentration for chemical fiber, which is composed of the following components according to the following weight proportion: 30 to 60% of tetrabromobisphenol A double (2.3 dibromopropyl) ether, 5 to 20% of antimony oxide, 1 to 5% of dibutyl tin laurate, 0.5 to 5% of triphenyl phosphite, 0.5 to 5% of epoxy soybean oil and 30 to 60% of a hot-melt adhesive carrier. The flame retardant master batch of polypropylene fiber with the high concentration of the present invention has the advantages of low dosage, high flame retardance, strong spinnability, etc.
Description
Technical field
The present invention relates to a kind of high concentration polypropylene fibre fire-retardant master granule and preparation method thereof, belong to polymeric material field.
Background technology
Polypropylene fibre is a kind of purposes chemical fibre very widely, but has inflammable shortcoming.In order to make its fire-retardant existing use contain the organic matter of phosphorus or halogen or the technology that inorganic matter is made the polypropylene fibre fire retardant, but effect is all undesirable, and the flame retardant effect that has is poor, the heat endurance deficiency that has, and the solid particle that has is many and thick and influence spinning technique.
Summary of the invention
The technical problem to be solved in the present invention is exactly the inflammable defective of existing polypropylene fibre, and a kind of high concentration polypropylene fibre fire-retardant master granule with fire resistance and preparation method thereof is provided.
For solving the problems of the technologies described above, the present invention adopts low-melting tetrabromobisphenol A two (2,3 dibromopropyls) the ether halogen flame is as the fire retardant main component, and the complexing agent composite with dibutyl tin laurate, triphenyl phosphite and epoxidized soybean oil is carrier as heat stabilizer, with the hot melt adhesive class.
The weight content of each composition of high concentration polypropylene fibre fire-retardant master granule of the present invention is as follows:
Two (2,3 dibromopropyl) the ether 30-60% of tetrabromobisphenol A
Antimony oxide 5-20%
Dibutyl tin laurate 1-5%
Triphenyl phosphite 0.5-5%
Epoxidized soybean oil 0.5-5%
Hot melt adhesive carrier 30 as one kind-60%
In order to satisfy the spinnability in the spinning technique, guarantee heat endurance and long changing the plate cycle that fire retardant is certain, should select Heat stability is good for use, can fusion or the little scattered fire retardant of particle diameter in spinning.The present invention selects two (2, the 3 dibromopropyl) ethers of tetrabromobisphenol A and the average grain diameter antimony oxide less than 0.2 μ m for use.Simultaneously, the present invention has adopted based on dibutyl tin laurate, is aided with epoxidized soybean oil, the heat stabilizing system of triphenyl phosphite.
In order to make master batch be easy to disperse in polypropylene fibre, temperature should be low as far as possible when making master batch, and make concentration concentration in master batch of fire retardant high as far as possible, does carrier and adopt the carrier of hot melt adhesive as master batch with polypropylene so the present invention gives up generally.
It is few that high concentration polypropylene fibre fire-retardant master granule of the present invention has a consumption, anti-flammability height, advantage such as spinnability is strong.
The specific embodiment
Embodiment one:
At first, prepare raw material by following weight proportion:
Two (2, the 3-dibromopropyl) the ether 38-40% of tetrabromobisphenol A
