preparation example Construction
[0030] The embodiment of the present invention also discloses a preparation method for the above-mentioned low-odor flame-retardant rubber floor, which is a method of extruding, calendering and vulcanization after mixing with an internal mixer, specifically including:
[0031] A. Weigh 15-25 parts of high styrene resin, 40-55 parts of kaolin, 2-4 parts of light stabilizer, 5-8 parts of antioxidant, 40-60 parts of inorganic flame retardant, 60- 80 parts, 4-8 parts of silane coupling agent, 2-5 parts of accelerator, and 3-6 parts of vulcanizing agent are mixed to form a mixed drug;
[0032] B. Cool the internal mixer with water, control the temperature of the working room of the internal mixer to 100°C to 150°C, adjust the speed of the internal mixer to 35 rpm, adjust the pressure of the top bolt on the internal mixer to 0.38MPa, and start the mixer for internal mixing. After 10 seconds of internal mixing, weigh 80-100 parts of styrene-butadiene rubber and add it to the internal...
Embodiment 1
[0038] A. Weigh 15 parts of high styrene resin, 40 parts of kaolin, 2 parts of BASF Tinuvin770DF, 8 parts of BASF 1076, 40 parts of magnesium hydroxide, 60 parts of melamine cyanurate, 4 parts of silicon 69, and 2 parts of accelerator DM. mixed to form a mixture;
[0039]B. Cool the internal mixer with water, control the temperature of the working room of the internal mixer to 100°C to 150°C, adjust the speed of the internal mixer to 35 rpm, adjust the pressure of the top bolt on the internal mixer to 0.38MPa, and start the mixer for internal mixing. After 10 seconds of internal mixing, weigh 80-100 parts of styrene-butadiene rubber and add it to the internal mixer to form a mixture, and adjust the speed to 38 rpm;
[0040] C. After 30 seconds for banburying, add the mixed drug into the banbury mixer for banburying;
[0041] D. Add 45 parts of white carbon black at 200 seconds for banburying, control and keep the temperature of the glue at 160°C for banburying and discharging...
Embodiment 2
[0045] Compared with Example 1, the present embodiment only changes the formula: the rubber floor includes the following parts by weight: 90 parts of styrene-butadiene rubber, 20 parts of high styrene resin, 50 parts of white carbon black, 48 parts of kaolin 3 parts, 3 parts of BASF Tinuvin770DF, 6 parts of BASF 1076, 50 parts of aluminum hydroxide, 70 parts of melamine cyanurate, 6 parts of silicon 69, 4 parts of accelerator TBzTD, 5 parts of vulcanizing agent, the preparation method still adopts embodiment 1 Preparation.
