Physical indexes of the household flame-retardant weather-resistant high-gloss ABS materials prepared in the examples 1-4 and the comparative examples 1-2 are shown in the following table 1.
TABLE 1 test results of examples 1-4 and comparative examples 1-2
Remarking: the notched izod impact strength test bars were 80 × 10 × 4mm in size and 2.75J in energy.
According to the test results in table 1, the household flame-retardant weather-resistant high-gloss ABS disclosed by the invention has very excellent flame retardant property, not only is excellent in weather resistance, but also is high in glossiness. Compared with the prior art, the method has the following advantages.
1. The ABS MG94 raw material with high fat solubility is adopted, the ABS MG94 raw material is a polymer formed by compounding small-particle-size rubber and small-molecular-weight AS, the flowability is high, and the processing and forming of the material can be still ensured after additives such AS flame retardant and the like are added;
2. antimony trioxide is added as a synergist of the brominated flame retardant, so that the flame retardant property of the material is improved, and the flame retardant with the thickness of 1.6mm can reach the VO level.
3. After the brightener is added, the glossiness of the composite material at an angle of 60 degrees is obviously improved and can reach more than 100, the appearance is black and bright, and the L value shows that the material is suitable for being used on household appearance materials and can replace parts with spraying effects.
4. After the stabilizer is added, the color difference value is lower than 2 after the xenon lamp irradiates for 96 hours, and is far smaller than that of ABS which is not added with the stabilizer in a comparative example, which shows that the stabilizer provides excellent weather resistance of the material, and the benzotriazole and the hindered benzoate in the stabilizer act synergistically, so that the material has excellent weather resistance.
It should be noted that the above embodiments are only used for illustrating the technical solution of the present invention, and are not limited; modifications to the embodiments, or equivalent substitutions of features therein, may be readily made by those skilled in the art; and such modifications or substitutions may not be made without departing from the spirit and scope of the present invention and the technical solutions of the embodiments.
