Abstract

The invention relates to eight bromo ether PET fibre and a preparation method thereof, wherein the raw materials comprises in percent of weight: 1-10% of eight bromo ether PET fibre master batches and the balance of PET slices, wherein the raw materials of the eight bromo ether PET fibre master batches comprises 1-10% of eight bromo ether, 0.1-1% of compatilizer and the balance of PET slices in weight percent. The invention has the advantages that the eight bromo ether PET fibre has excellent flame retardant performance and good flame retardant effect, can be carried out by using the original technology, is simple and convenient, and is widely applied.

Description

【Technical field】 [0001] The invention relates to the technical field of flame-retardant fibers, in particular to octabromoether PET (polytrimethylene terephthalate) fibers and a preparation method thereof. 【Background technique】 [0002] Generally, flame retardants can be divided into two categories: organic flame retardants and inorganic flame retardants according to their chemical composition. Organic flame retardants are divided into two series: phosphorus-based and halogen-based. The former is mostly liquid at room temperature, has a large amount of smoke, and is toxic. It requires a large amount of H and O elements in the flame-retardant structure to dehydrate and form a carbonized layer, so its application is greatly limited. Halogenated flame retardants mainly include chlorine and bromine. From the perspective of usage, the use of brominated flame retardants is more common. This is mainly because bromide is relatively less corrosive and toxic after thermal decompo...
