Problems solved by technology

[0002] Halogen-free flame-retardant polyamide materials are widely used in electronics, automobiles and other industries, and have relatively excellent comprehensive mechanical properties, heat resistance, etc. Further improvement, and the existing related products can no longer meet the relevant needs in terms of aging resistance and weather resistance, which has become one of the important factors limiting the application of this type of product. The improvement effect is extremely limited by using conventional anti-oxidation systems. Therefore, it is necessary to Effectively improve the performance of materials through the overall optimization of the entire formulation system

Embodiment 2、3

[0052] From the comparison of Examples 1 to 3, it can be seen that the aliphatic polyamide in Example 1 is PA 66, and its aging resistance and weather resistance are better than those of Examples 2 and 3;

[0053]From the comparison of Examples 4 to 6, it can be seen that the aromatic polyamide in Example 4 is PA 6T / 6I, the aromatic polyamide in Example 5 is PA66 / 6T, and the aromatic polyamide in Example 6 is PA. MXD6, aging resistance in embodiment 4,5, weather resistance are better than embodiment 6;

Embodiment 7

[0054] Comparing Example 4 with Example 7, it can be seen that the char-forming agent in Example 4 is dipentaerythritol, the char-forming agent in Example 7 is tripentaerythritol, and the aging resistance and weather resistance in Example 4 are better than those in Example 4. 7;

[0055] Comparing Examples 4, 8, 9 to 10 shows that in Examples 4 and 8, the weight ratio of aluminum diethylphosphinate, boehmite and zinc borate is: (15-16): (4-5): (2~3); And in embodiment 9~10, the weight ratio of acid aluminum, boehmite and zinc borate is not in (15~16):(4~5):(2~3) scope, embodiment 4, The aging resistance of 8, weather resistance are better than embodiment 9,10;

Embodiment 12

[0056] Comparing Examples 4, 13, and 14 with Example 12, it can be seen that in Examples 4, 13, and 14, the aromatic polyamide is in the range of 15 to 25 parts, the char-forming agent is in the range of 1.5 to 3 parts, and in Example 12 The aromatic polyamide is not in the range of 15-25 parts, and the char-forming agent is not in the range of 1.5-3 parts. The aging resistance and weather resistance in Examples 4, 13, and 14 are better than those in Example 12;

[0057] From Example 4 and Comparative Examples 1 to 8, it can be seen that the aromatic polyamide and the char-forming agent are not introduced, or one of the aromatic polyamide and the char-forming agent is introduced separately, or both substances are introduced simultaneously, However, the introduction amount or composition is not within the preferred range, and the overall anti-aging, weather resistance and flame retardancy properties of the material are significantly worse than those of Example 4 of the present a...

Abstract

The present invention disclose a combination of halogen -free flame retardable polyamide, including components of the following weights: 20-50 copies of fatty polyamide, 10 to 30 parts of aromatic polyamide, 20 to 30 copies of halogen -free flame retardant, glass10-50 parts of fiber, 1 to 5 copies of charcoal and 0 to 5 parts of the auxiliary; at least one of the aromatic polyamide is PA66 / 6T, PA MXD6, PA6T / 6i;At least one of the two -seasons of pentaol and three seasons.Among the composite materials for halogen -free flame retardant polyamide, the aromatherapy polyamide itself has the ability to resist the capacity of high temperature resistance and the formation of a carbon in the process of aging.Amide composite materials have good weather resistance, aging resistance, flame retardant performance.At the same time, the present invention also disclosed the preparation method of halogen -free flame retardable polyamide composite materials.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a highly weather-resistant, aging-resistant halogen-free flame-retardant polyamide composite material and a preparation method thereof. Background technique [0002] Halogen-free flame-retardant polyamide materials are widely used in electronics, automobiles and other industries, and have relatively excellent comprehensive mechanical properties, heat resistance, etc. Further improvement, and the existing related products can no longer meet the relevant needs in terms of aging resistance and weather resistance, which has become one of the important factors limiting the application of this type of product. The improvement effect is extremely limited by using conventional anti-oxidation systems. Therefore, it is necessary to Through the overall optimization of the entire formula system, the performance of the material can be effectively improved. Contents of the invent...
