Problems solved by technology

Although this MPR intumescent flame retardant system can overcome the shortcomings of red phosphorus to a certain extent, when it is used in this type of glass fiber reinforced material, under high temperature and strong shear, the capsule layer of red phosphorus is inevitable. Destroyed or partially destroyed, it will still deteriorate and fail

Abstract

The invention provides a low-precipitation red phosphorus flame-retardant terylene material and a preparation method thereof. The low-precipitation red phosphorus flame-retardant terylene material is prepared from the following components in parts by weight: 20 to 35 parts of microencapsulated red phosphorus flame retardant, 55 to 65 parts of terylene, 5 to 10 parts of a synergistic flame retardant, 5 to 10 parts of talcum powder, 0.5 to 1 part of an antioxidant, 0.5 to 1 part of an acid absorbent, 0.5 to 1 part of a stabilizing agent and 0.2 to 0.5 part of a lubricating agent; the low-precipitation red phosphorus flame-retardant terylene material is obtained by melting and blending the above-mentioned components and adding 15 to 25 parts of glass fiber for granulation. The preparation method comprises the steps of weighing, mixing, foaming, curing and activation. The low-precipitation red phosphorus flame-retardant terylene material provided by the invention has the beneficial effect of low red phosphorus precipitation; furthermore, the preparation method is simple and large-scale production is suitable.

Description

technical field [0001] The invention relates to the technical field of flame-retardant materials, in particular to a low-precipitation red phosphorus flame-retardant polyester material and a preparation method thereof. Background technique [0002] Red phosphorus is an excellent halogen-free flame retardant, which has the advantages of less addition amount and high flame retardant efficiency. However, when ordinary red phosphorus is exposed to the air, it is easy to oxidize, absorb moisture, and has poor thermal stability. At the same time, red phosphorus has poor compatibility with most polymers, which affects the flame retardancy and mechanical properties of the product, so its application is limited. In the prior art, red phosphorus is usually coated with melamine resin to make microencapsulated red phosphorus (MRP), and then compounded with pentaerythritol and melamine to obtain an intumescent resistor with MRP as the matrix. Flame retardant system, used in polymer mate...
