Description
Technical field
The invention belongs to the fire-retardant film technical field, be specifically related to a kind of PET fire-retardant film master batch and preparation method thereof, PET fire-retardant film goods.
Background technology
The PET fire-retardant film at home so that the world be all a new technology and technical barrier.Truly flame-retardant V 0-stage and every mechanical property are all good in the world, only have Mitsubishi.Its technology is in the area of security monopoly position, and its product price is high.Domesticly also phosphoric acid ester is introduced in the PET molecular skeleton by the transesterify mode in research, but that actually operating is got up is very inconvenient, of a high price, and is difficult to accomplish the V0 level of real meaning, so present stage is difficult to expansion.
People attempt with the convenient and practical additive flame retardant of tradition, but exist consistency, dispersiveness, interface property and persistence poor and to operative employee's toxicity problem, and particularly poor toughness is without Practical significance.In order to address these problems, people adopt fire-retardant master granule, have the people to make carrier with PE, PP, EVA, but all have the problem of the poor and poor toughness of consistency.For this reason, people make carrier with PET, but the PET fire-retardant film of making, and poor toughness is without Practical significance.So people find various toughner, some toughner adds, and makes on the contrary its product become fragile, and some toughner adds, and make moderate progress, but effect is little, and high cost, do not have practical value.When adopting fire-retardant master granule, its adding proportion is difficult to hold in addition, and adding proportion is little, the auxiliary agent content such as requirement master batch fire retardant are many, not only doing master batch, to add man-hour very difficult, and, when film processed, dispersed uncompatibility is poor, film product is fire-retardant inhomogeneous, adding proportion is large, and master batch is many containing carrier, the oxidative degradation when the processing master batch of a lot of carriers, make the film of doing more crisp, poor practicability.
Summary of the invention
For above-mentioned deficiency, one of the object of the invention is, a kind of environmental protection, nontoxic, consistency and good dispersity are provided, and can produce the PET fire-retardant film master batch of the PET fire-retardant film of good toughness and good flame retardation effect.
Two of the object of the invention is, a kind of preparation method who prepares above-mentioned PET fire-retardant film master batch is provided, and this preparation method's technique is simple and easy, is easy to realize, production efficiency is high, has effectively improved production efficiency.
Three of the object of the invention is, a kind of PET fire-retardant film goods that adopt above-mentioned PET fire-retardant film master batch to make are provided, and good toughness, the tensile strength of these PET fire-retardant film goods are high, good flame retardation effect
