Problems solved by technology

Although polyamide has excellent mechanical properties, electrical properties and anti-corrosion properties, its water absorption cannot be avoided, and its water absorption rate can reach 2%.
As we all know, water is an excellent conductor of electricity. As long as there is a large amount of water in the polyamide matrix, the mechanical properties and dimensional stability will change, and hydrolysis will also occur, and there will be hidden dangers in safety performance.

Embodiment 1

[0011] A resin composition with high thermal conductivity and high safety, the composition comprises the following components by weight percentage: 70% polyamide, 25-55% filler, 0.1-3% coupling agent, 24% toughening agent, water-resistant 7% solution agent, 6% stabilizer, 6% lubricant, 0.1-5% nucleating agent.

[0012] The thermally conductive and insulating resin composition based on polyamide has good mechanical properties, weather resistance and excellent insulation and thermal conductivity; due to the addition of polycarbodiimide hydrolysis-resistant agent, it can reduce the hydrophilicity of polyamide and inhibit polyamide The hydrolysis of amide enhances the stability and safety of the material, thereby solving the potential safety hazards that common polyamide insulating plastics are prone to produce due to the presence of moisture. It can be widely used in industries such as electronics and lighting.

Description

technical field [0001] The present invention relates to a thermally conductive and highly safe resin composition. Background technique [0002] As we all know, in the LED lighting industry, the lampshade of LED lamps has always been made of aluminum alloy or electroplated aluminum material, which has the advantage of fast heat dissipation. However, while it dissipates heat quickly, aluminum metal is also an excellent conductor of electricity. This kind of thermal and electrical conductivity and non-corrosion-resistant metal characteristics will bring unsafe factors when it encounters water, fog, or electric leakage or short circuit. As far as the metal itself is concerned, this characteristic cannot be eliminated. At the same time, the resources for making metal are destructive, the production energy consumption is high, the processing cost is high, and the style changes little. These factors have prompted the large-scale application of new polymer materials as soon as pos...
