Abstract
The invention discloses a method for synthesizing reactive halogen-free flame-retardant unsaturated polyester resin. The method is characterized by taking dihydric alcohol, dibasic acid or dibasic acid anhydride, reactive phosphorus flame retardants such as 2- carboxyethyl (phenyl) phosphinic acid and phenyl hydroxymethyl phosphinic acid, and reactive silicon flame retardants such as dihydroxy diphenyl silane and dihydroxy dimethyl silane as basic materials, conducting esterification and polycondensation under the conditions of catalysts such as dibutyltin oxide and sodium acetate, and then adding diluent, thus preparing the halogen-free flame-retardant unsaturated polyester resin. The resin prepared by the method is especially applicable to the production of unsaturated polyester resin moulding compounds, glass fiber reinforced plastics and electrical plastic products, can meet the requirements of products on flame retarding and lightweight and has good properties.
Description
Technical field
The invention belongs to the preparation method of macromolecular compound, relate to a kind of synthetic method of response type halogen-free flameproof unsaturated polyester resin.The response type halogen-free flameproof unsaturated polyester resin of this method preparation is specially adapted to the manufacturing of matrix materials such as flame-retarded light unsaturated polyester die plastic or glass reinforced plastic, electrical plastics product.
Background technology
The develop rapidly of world economy and social huge advance made; how all to be faced with between resource exhaustion, environment protection and the Sustainable development equilibrated strategic issue, and to relate to the great moulding compound of market consumption that the present invention is correlated with and the technology and the market trend of fibre glass product manufacture is environment friendly halogen-free fireproof, lightweight, the high mechanical electric performance of products such as matrix materials such as unsaturated polyester die plastic or glass reinforced plastic, electrical plastics.
At present, in the reaction-type flame-retarding unsaturated polyester of producing, great majority use halogen containing flame-retardant both at home and abroad, and the synthetic unsaturated polyester has flame retardant effect preferably; This class halogenated flame retardant is introduced unsaturated polyester, produces a large amount of dense smoke and corrodibility toxic gas during burning, to environment and people's the bigger threat of life security formation.
In the prior art, Chinese patent application publication number CN101514253A discloses environment-friendly flame-retarded unsaturated polyester resin and preparation method thereof, with in 2-carboxyethyl phenyl Hypophosporous Acid, 50 (CEPPA) and the phenyl methylol Hypophosporous Acid, 50 (HMPPA) one or both is the response type halogen-free flame retardants, is additive flame retardant with in triphenylphosphate, triethyl phosphate, the methyl-phosphoric acid dimethyl ester one or more.If this class reactive flame retardant without dibasic alcohol anticipate and and materials such as dibasic alcohol, diprotic acid add the reactor direct reaction together, phosphate group on CEPPA or the HMPPA is difficult to participate in reaction, it is difficult to cause the system acid number to descend, and the resin cast surface has the serious phenomenon that is clamminess.The adding of additive flame retardant has considerable influence to the mechanical property of unsaturated polyester, and the addition type organic fire-retardant also has the problem of a loss, can increase with the rising loss amount of envrionment temperature, influence flame retardant effect; Add styrenic crosslinker, vinylbenzene has wick effect, makes the unsaturated polyester resin flame-retardant effect undesirable.To sum up, existing reaction, interpolation mixed type phosphor-containing flame-proof unsaturated polyester resin all have increasing tougheness because of most of addition type organic fire-retardants, the flexible increase of goods, rigidity are descended, and organic fire-retardant also has the problem of a loss, envrionment temperature has considerable influence to loss, temperature height, loss amount are just big, influence flame retardant effect.
