Embodiment 1

[0036] The matrix resin with flame retardant effect was synthesized in a four-necked flask equipped with a stirrer, a thermometer and a reflux condenser.

[0037] Main raw materials: methyl propylene glycol, diethylene glycol, maleic anhydride, tetrabromophthalic anhydride, tribromoneopentyl alcohol, chlorostyrene, styrene accessories;

[0038] The ratio of each raw material is as follows: (the ratio is the consumption ratio, that is, the percentage of the weight of the material to 100 parts of the finished flame-retardant matrix resin)

[0039]

[0040] Excipients: copper naphthenate, titanic acid liquid catalyst, compatible wetting and dispersing agent, defoamer (silane)

[0041] ppm is one millionth of the total weight of the resin

[0042]

[0043]

[0044] The key points of the synthesis process: process temperature rise, high positive pressure catalytic reaction in the front stage, and ultimate negative pressure evacuation reaction in the latter stage

[0045]...

Embodiment 2

[0061] The flame retardant unsaturated polyester resin of the present embodiment comprises the following components in parts by weight:

[0062]

[0063] The flame retardant unsaturated polyester resin also includes by weight parts:

[0064]

[0065] Inhibitor: TBC tris(2,3-dibromopropyl)isocyanurate 150ppm.

[0066] The preparation method is the same as in Example 1.

Embodiment 3

[0068] The flame retardant unsaturated polyester resin comprises the following components in parts by weight:

[0069]

[0070] The flame retardant unsaturated polyester resin also includes by weight parts:

[0071]

[0072] Inhibitor: TBC tris(2,3-dibromopropyl)isocyanurate 150ppm.

[0073]The preparation method is the same as in Example 1.

[0074] Blending modification of unsaturated flame retardant matrix resin by adding new flame retardant in different proportions

[0075] Resorcinol bis-diphenyl phosphate is a high-molecular-weight organophosphorus flame retardant, which appears to be a clear liquid; it has a high phosphorus content of 10.8%. It has the characteristics of high flame retardancy, low addition amount, and little influence on the physical properties of the finished product. It has dual functions of flame retardant and plasticizing, which can make the flame retardant completely non-halogenated, improve the flow processing performance and reduce ablat...

Abstract

The invention discloses novel environment-friendly flame-retardant modified unsaturated polyester resin and a preparation method thereof. By synthesizing flame-retardant unsaturated polyester matrix resin and adopting a high-temperature pressurized catalysis and vacuumizing double-process control optimization production process, and a novel environment-friendly flame retardant resorcinol bis-diphenyl phosphate is added based on the flame-retardant matrix resin with certain flame-retardant efficiency, so that the flame-retardant effect is improved by more than 15%.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a novel environmentally friendly flame retardant modified unsaturated polyester resin and a preparation method thereof. Background technique [0002] With the increasing awareness of global safety and environmental protection, people have higher and higher requirements for fire safety and flame retardancy of products. Halogen-free, low-smoke, low-toxic environment-friendly flame retardants have become the goal pursued by people. Flame-retardant unsaturated polyester resins are widely used in construction, shipbuilding, automobile industry, chemical equipment, light industrial products and sporting goods and other fields. The existing unsaturated flame retardant resins are divided into flame retardant type and additive type, but the two types of flame retardant products are difficult to achieve a balance between environmental protection and flame retardant effect...
