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.

Abstract

The invention discloses an oil tea fruit shell powder adding agent and a preparing method and application therefore, and relates to an adhesive adding agent and a preparing method and application thereof. The problem that existing aldehyde adhesive difficultly glues a straw-based panel effectively, and panel sticking exists in isocyanate adhesive is solved. The adding agent comprises modified oil tea fruit shell powder and modified nano-montmorillonite. The method comprises the steps of firstly, preparing of modified oil tea fruit shell powder; secondly, preparing of the modified nano-montmorillonite and thirdly, preparing of the oil tea fruit shell powder adding agent. The modified oil tea fruit shell powder obtained through the method is added into the adhesive, the straw-based panel is bonded, the gluing strength and water resistance are improved, and the agent is used for the field of the straw-based panel adhesive adding agent.

Description

technical field [0001] The invention relates to an adhesive additive, a preparation method and application thereof. Background technique [0002] my country is a large agricultural country, and a large amount of food and economic crops are planted every year, and the crop straw resources are huge (including wheat straw, rice straw, sorghum stalks, corn stalks, hemp stalks, cotton stalks, tobacco stalks, etc.). During the harvest season of crops every year, a large amount of straw is directly burned in the farmland because it is not recycled, which not only causes air pollution, destroys the soil structure, reduces the quality of farmland, but also is a great waste. The emergence of the straw-based panel industry can achieve waste utilization, help to solve environmental problems, and can effectively solve the problem of insufficient wood resources, which is of great significance. [0003] In the production process of straw-based panels, it is necessary to go through the pro...
