Problems solved by technology

[0005] However, the application of PEEK modified by ordinary inorganic salt particles in the field of electronic cigarettes still has the following defects: 1. The high-shear viscosity of glass fiber modified PEEK material is high, the processing cost is high, and the energy consumption is large; The coefficient is too high, which is not conducive to energy saving, poor user experience, and reduces the life cycle of other electronic accessories; there are biological risks 2. The thermal conductivity of inorganic salt modified polyetheretherketone material is lower than that of glass fiber modified polyether ether Ketone, but the heat insulation effect still fails to meet the needs of use; the heat distortion temperature is low

[0028] A preparation method of polyether ether ketone modified granulated material with low thermal conductivity, the specific steps are as follows:

[0029] 1. Preparation of modified diatomite:

[0030] Take 100 parts of roasted diatomaceous earth, pour it into 1000 parts of the silicone monomer aqueous dispersion with a specified mass concentration, and continue stirring for 20 minutes after fully dispersing; filter the dispersion until there is no liquid material on the surface of the material; take out the filter cake, and use 300 parts of Disperse the filter cake with pure water, stir quickly for 20 minutes, and then centrifuge to separate the solid material; repeat the washing twice; take out the solid material obtained by centrifugation, spread it evenly, and the thickness does not exceed 10mm, put it in an oven at 180°C for 45 minutes, and then transfer it to 450°C Dry in an oven for 120 minutes; when the temperature of the material drops to 120±10°C, move it into a d...

Abstract

The invention relates to a heat-insulating material, particularly relates to a polyether-ether-ketone modified pelletizing material with low heat-conducting coefficient as well as application thereof,and belongs to the technical field of a macromolecular modified material. The polyether-ether-ketone modified pelletizing material with low heat-conducting coefficient is obtained by extruding and pelletizing the following components in percentage by mass: 60 to 89.9 percent of polyether-ether-ketone resin, 10 to 39.5 percent of modified diatomite and 0.1 to 5 percent of carbon nanotube; the modified diatomite is obtained by sequentially performing purification, modification and roasting treatment on roasted diatomite and / or fluxing roasted diatomite raw materials; and the roasting temperature of the roasted diatomite and / or fluxing roasted diatomite raw materials is not less than 450 DEG C and the roasting time of the roasted diatomite and / or fluxing roasted diatomite raw materials is not less than 2 hours. Compared with the common polyether-ether-ketone modified pelletizing material, the polyether-ether-ketone modified pelletizing material with low heat-conducting coefficient has better heat-insulating effect and has high strength and size stability.

Description

technical field [0001] The invention relates to a heat insulating material, in particular to a polyetheretherketone modified granulation material with low thermal conductivity and its application, belonging to the technical field of polymer modified materials. Background technique [0002] Polyether ether ketone is a high-performance thermoplastic special engineering plastic, which is widely used in aerospace, electronic communication, medical equipment, and civil high-tech fields due to its excellent performance. Polyetheretherketone is a thermoplastic resin with a melting point of 343°C. Its long-term use temperature can reach 260°C. The weight loss rate in the air is only 2% at a constant temperature of 420°C for 2 hours. After 30% glass fiber reinforcement, the heat distortion temperature (ISO 75-f , 1.8MPa) up to 328°C. [0003] At present, PEEK with low thermal conductivity and high heat distortion temperature is mainly glass fiber modified polyether ether ketone. At...
