[0044] Preparation of solid-liquid mixture:

[0045] Put aloe vera leaves and rice leaves into an oven at a mass ratio of 1:3, dry for 2 hours at a temperature of 95°C, and put them into a planetary ball mill after drying at a speed of 90r / min and a ball-to-material ratio of 5:1. Grinding for 3 hours to obtain the grinding product, put the grinding product and hydrochloric acid with a mass fraction of 11% into a beaker at a mass ratio of 1:10, and let stand at room temperature for 2 hours to obtain a solid-liquid mixture.

[0046] Preparation of the reaction mixture:

[0047] Place the above beaker in an ultrasonic oscillator, vibrate for 3 hours at a frequency of 38 kHz to obtain an oscillation product, filter the oscillation product to obtain a filter residue, wash the filter residue with distilled water 4 times, and put the filter residue and distilled water into the reaction at a mass ratio of 1:5 In the still, the closed reaction kettle was filled with nitrogen into the ...

Embodiment 3

[0057] Preparation of solid-liquid mixture:

[0058] Put aloe leaves and rice leaves into an oven at a mass ratio of 1:3, dry for 3 hours at a temperature of 100°C, and put them into a planetary ball mill after drying at a speed of 100r / min and a ball-to-material ratio of 5:1. Grind for 4 hours to obtain a grinding product, put the grinding product and 12% hydrochloric acid in a mass ratio of 1:10 into a beaker, and let stand at room temperature for 3 hours to obtain a solid-liquid mixture.

[0059] Preparation of the reaction mixture:

[0060] Place the above beaker in an ultrasonic oscillator, vibrate for 4 hours at a frequency of 40 kHz to obtain an oscillation product, filter the oscillation product to obtain a filter residue, wash the filter residue with distilled water for 5 times, and put the filter residue and distilled water into the reaction at a mass ratio of 1:5 In the still, the closed reaction kettle was filled with nitrogen into the reaction kettle, the pressur...

Abstract

The invention relates to a preparation method of high heat-resistant antibacterial toy paint, and belongs to the technical field of paint preparation. The preparation method comprises the following steps: using aloe leaves and rice leaves as raw materials to prepare a reaction mixture, then mixing the reaction mixture with ginkgo leaves and ginkgo tree roots and fermenting, adding aluminum chloride to obtain a reaction filtrate, and finally mixing the reaction filtrate with an organic solvent and other auxiliary agents and stirring to obtain the high heat-resistant antibacterial toy paint. Byextracting nutrients from the aloe leaves and generating organo-functional groups such as carboxyl groups, hydroxyl groups, phenolic hydroxyl groups on the surface, the adhesion between various molecules inside the paint is enhanced, and the adhesion between the paint and the toy material is improved. Meanwhile, the ginkgo tree grows a large amount of ginkgo biloba endophytic bacteria during the fermentation process, which helps to improve the antibacterial property. By introducing aluminium ions into the aloe nutrients and various fiber components, aluminium oxide grows on the surface of fiber and then toughness of the fiber is enhanced. Meanwhile, the toy paint has good heat resistance and has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a high heat-resistant antibacterial toy coating, which belongs to the technical field of coating preparation. Background technique [0002] my country is the largest toy manufacturer and exporter in the world. 70% of the world's toys are manufactured in my country, but the qualified rate of toys in China's domestic market is only 76.3%. problems such as trade barriers. [0003] At present, most of my country's toy products use plastic or wood as the substrate, and the toys are sprayed with solvent-based paints. However, solvent-based coatings are flammable and explosive, and there are many unsafe factors in the process of production, storage, transportation and use. Moreover, because the human body takes in too much heavy metals through contact with toys, it will cause chronic poisoning. Some heavy metals can remain in the brain and internal organs, causing permanent damage to the liver, kidneys, etc., ...
