specific Embodiment approach 1
[0037] Specific embodiment one: the present embodiment camellia oleifera shell powder additive comprises modified camellia oleifera shell powder and modified nano-montmorillonite, and the quality of the modified nano-montmorillonite is 0.5% to 0.5% of the quality of modified camellia oleifera shell powder 1%.
specific Embodiment approach 2
[0038] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the preparation method of the modified camellia oleifera shell powder comprises the following steps:
[0039] ①Crush the camellia oleifera shell and pass through a 40-60 mesh sieve to obtain camellia oleifera shell powder, add 0.5-1.5mol / L NaOH solution and epichlorohydrin into the camellia oleifera shell powder, and then stir at 50-60°C Modified for 30 to 60 minutes, then washed the camellia oleifera shell powder with deionized water until neutral, and dried at 65 to 80°C for 3 to 5 hours to obtain a modified camellia oleifera shell powder;
[0040] The mass ratio of camellia oleifera shell powder to NaOH solution is 1g: (10-25) mL, and the volume ratio of camellia oleifera shell powder to epichlorohydrin is 1 g: (1-8) mL;
[0041] ② Add hyperbranched polyamide solids and deionized water to the primary modified Camellia oleifera shell powder, then stir at 25-30°C for 30-60 m...
specific Embodiment approach 3
[0044] Embodiment 3: This embodiment is different from Embodiment 2 in that: the hyperbranched polyamide is an aliphatic hyperbranched polyamide, an aromatic hyperbranched polyamide or aliphatic and aromatic mixed hyperbranched polyamide. Others are the same as in the second embodiment.
