[0069] The ceramic composite material of this embodiment has two preparation methods, the first preparation method includes the following steps:
[0070] ① 100 parts of the polyolefin, 0-100 parts of silicone rubber, 1-100 parts of silicon dioxide, 0-30 parts of silicone oil, 0.00001-10 parts of platinum complex and / or platinum compound calculated as platinum, coupling agent 0-10 parts, 0-10 parts of antioxidant are kneaded in the kneader;
[0071] ② Vacuumize the kneader, keep the vacuum at -0.1~-0.04Mpa, and keep the temperature at 100~200°C;
[0072] ③Put 1-250 parts of vitrified powder into the kneader to make vitrified powder mixed with kneaded polyolefin, silicone rubber, silicon dioxide, silicone oil, platinum complex and / or platinum compound, coupling agent, antioxidant The agent is mixed evenly to form a group of ceramic rubber;
[0073] ④ move the lumpy ceramic rubber out of the kneader and cool it;
[0074] ⑤ Knead the cooled lump-shaped ceramic rubber on an open...
Embodiment 1
[0095] Take 100 parts of polyethylene, 20 parts of silicon dioxide, 1 part of methyl silicone oil, 0.01 part of 1000ppm isopropanol solution of chloroplatinic acid, 0.1 part of KH560 coupling agent, and 20 parts of aluminum oxide, and make ceramic composite according to the above The first preparation method of the material prepares the ceramic composite material. When the ceramic composite material is vulcanized and molded, 1 part of 2,5-dimethyl-2,5-bis(t-butylperoxy)hexane is added.
Embodiment 2
[0097] Take 100 parts of ethylene-vinyl acetate copolymer (EVA), 100 parts of silicon dioxide, 30 parts of hydroxyl silicone oil, 10 parts of 1000ppm isopropanol solution of chloroplatinic acid, 0.1 part of A171 coupling agent, 150 parts of silicon dioxide According to the first preparation method of the ceramic composite material above, the ceramic composite material is prepared. When the ceramic composite material is vulcanized and formed, 2 parts of 2,4-dichlorobenzoyl peroxide (commonly known as double-two-four) are added. .

Abstract
The invention discloses a ceramic composite material. The ceramic composite material contains the following materials in parts by weight: 100 parts of polyolefine, 0-100 parts of silicon rubber, 1-100 parts of silica, 0-30 parts of silicone oil, 0.00001-10 parts of platinum in platinum complex or platinum compound, 0-10 parts of coupling agent, 1-250 parts of ceramic powder, 0-10 parts of antioxidant and 0.01-10 parts of vulcanizing agent. A preparation method of the ceramic composite material comprises the steps of milling the materials in a kneader, vacuumizing, adding into the kneader, milling uniformly to form lumpish ceramic rubber, cooling, adding the vulcanizing agent, and carrying out open milling, thereby obtaining the ceramic composite material. The ceramic composite material is easy to process and low in production cost and can be ablated into a ceramic-like shell, so as to protect an ablated object from being damaged. According to the ceramic composite material disclosed by the invention, due to the addition of the platinum complex or platinum compound, the sintering temperature for the ceramic composite material can be lowered, and the reaction rate of preparation can be increased, so that the production efficiency is increased, and the production cost is reduced.
Description
technical field [0001] The invention relates to a polymer, in particular to a polymer with fire-resistant function. Background technique [0002] At present, most fire-resistant and flame-retardant cables use magnesium oxide mineral insulation or mica tape winding to achieve fire-resistant functions. [0003] However, magnesia mineral refractory insulated cables have the following disadvantages in manufacturing and application: first, the equipment cost is high, and magnesia mineral refractory insulated cables require special production and processing equipment, which is expensive and the equipment cost is high; second, the production cost High, because the outer sheath of the magnesia mineral refractory insulated cable is all copper, the price of copper is high, making the production cost higher, and it is limited to a certain extent in terms of practical application; Laying, installation and use are inconvenient, because copper sheathed magnesium oxide mineral fire-resi...
