Abstract

The invention provides a preparation method of flame-retarding compounded vinyl unsaturated alkyd resin. The compounded vinyl alkyd resin includes vinyl resin, unsaturated alkyd resin, antimonous oxide, a dispersant, an active diluent, white carbon black, a polymerization inhibitor, an accelerant, a curing indicator, and a low-volatilization inhibitor. The preparation method comprises the steps of: a) mixing the vinyl resin, the unsaturated alkyd resin and the active diluent, adding the white carbon black and intensively stirring the mixture for 20 min until the white carbon black is uniformlydispersed in the system; b) successively adding the dispersant, the polymerization inhibitor, the low-volatilization inhibitor, the curing indicator and the accelerant equivalently, after one raw material is added, the system is completely stirred and then the next one raw material is added, so that the raw materials are uniformly mixed; c) packaging the product and storing the product at low temperature to obtain the flame-retarding compounded unsaturated vinyl alkyd resin. The flame-retarding compounded unsaturated vinyl alkyd resin has advantages of excellent market adaptability, high performance cost ratio, low volatilization of harmful gas and high operability.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant compound vinyl alkyd resin and a preparation method thereof. Background technique [0002] Unsaturated Polyester Resin (UPR, Unsaturated Polyester Resin) is formed by polycondensation of diol and unsaturated dibasic acid at high temperature. Its linear polymer chain contains polymerizable double bonds, and under the action of initiator, it contains double bonds with each The monomers such as styrene, methyl methacrylate, etc. are copolymerized to form a three-dimensional structure, which is a thermosetting plastic; it has the advantages of good performance, convenient curing and low price; it is widely used in construction, shipbuilding, automobile industry, and chemical equipment , Light industrial products and sporting goods. However, this type of plastic is a hydrocarbon and is flammable. It is important to study the flame retardant properties of unsaturated poly...
