[0059] The first step, pretreatment of raw materials: remove impurities from wild sumac seeds to obtain the fleshy part of sumac seeds, and then crush them into fine powder. lower fleshy part

[0060]The second step, leaching: use a non-polar solvent to carry out horizontal rotation continuous leaching of the fine powder to obtain an extracting solution. The extraction temperature is 10°C-90°C. For example, the temperature can be selected as: 20°C, 30°C, 40°C, 55°C, 60°C, 65°C, 70°C, 80°C, 85°C, the feeding speed is 50g / min-2000g / min, for example, it can be selected as: 60g / min, 80g / min, 100g / min, 300g / min, 500g / min, 800g / min, 900g / min, 1100g / min, 1300g / min, 1700g / min, 1900g / min, the spray amount of non-polar solvent is 1L~30L / min, for example, it can be selected as : 1.5L / min, 3L / min, 5L / min, 6L / min, 8L / min, 12L / min, 15L / min, 17L / min, 18L / min, 20L / min, 23L / min, 24L / min, 26L / min, 28L / min, 29L / ...

Embodiment 2

[0065] The present invention also utilizes the vacuum concentrate prepared by the method of Example 1 to prepare a composite nanomaterial:

[0066] The present invention also provides a kind of wild sumac wax composite nano material, comprising described wild sumac wax vacuum concentrate and inorganic nano material, wherein, the mass ratio of inorganic nano material and described wild sumac wax vacuum concentrate is 1:( 100-1000). For example, the mass ratio can be selected as: 1:150, 1:180, 1:250, 1:300, 1:400, 1:500, 1:600, 1:700, 1:750, 1:860, 1:900 , 1:950, 1:980, the inorganic nano-material can be selected as one of nano-silicon dioxide and nano-titanium dioxide, and its particle size is less than 100nm.

Embodiment 3

[0068] A method for preparing the wild sumac wax composite nanomaterial described in Example 2, heating the described wild sumac wax vacuum concentrate to 50°C-120°C, for example, can be selected as: 60°C, 80°C, 90°C, 110°C ℃, add inorganic nanomaterials, keep stirring at the above temperature for 5-40 minutes, for example, 8 minutes, 10 minutes, 15 minutes, 30 minutes, 35 minutes can be selected. The stirring time is to form a homogeneous wax liquid, which is granulated through the nozzle of the spherical granulator The high-temperature area in the machine forms spherical droplets, which are gradually cooled in the water cooling tower, and then sprayed with water for secondary cooling, then enter the draining screen, part of the free water is removed, and white paint wax particles are obtained, and then air-dried and dehydrated by the fluidized bed , forming spherical lacquer wax particles, the spherical particle diameter of molding and granulation is 0.5-5mm, which is titaniu...

Abstract

The invention discloses a leaching method for wild sumac wax which comprises the following procedures: seeds of the wild sumac are purified to obtain flesh parts of the seeds of the wild sumac, then the flesh parts are crushed into fine powder, the non-polar solvent is used to make a rotary type continuous leaching to the fine powder to obtain the leaching liquor, the leaching liquor is made thermal insulation, decolored, cylindrical type and plate type secondary filtration and vacuum condensation; the invention also provides a wild sumac wax composite nanometer material which comprises the wild sumac wax vacuum condensate and inorganic nanometer material. The invention also provides a preparation method for the wild sumac wax composite nanometer material, which comprises the following steps: the wild sumac wax vacuum condensate is heated, added with the inorganic nanometer material, made thermal insulation and stirred to form the homogeneous wax liquid, spherical liquid drops are formed in the high-temperature area of a spherical granulator through a nozzle of the spherical granulator, and gradually cooled in a water cooling tower to dehydrate partial free water to obtain white sumac wax particles which are dehydrated then, and spherical sumac wax particles are formed. The invention has the advantages that the invention prepares the wild sumac wax with high purity, and particularly improves the performance of the wild sumac wax nanometer material.

Description

technical field [0001] The invention relates to a wax purification method, a composite material and a preparation method, in particular to a method for extracting wild sumac wax, a wild sumac wax composite nano material and a preparation method. Background technique [0002] Wax is divided into natural wax and synthetic wax according to its source, and synthetic wax is a petrochemical product. Natural wax includes animal wax, vegetable wax and mineral wax. Animal wax and vegetable wax are also called biological wax. They do not contain harmful substances and have many unique advantages. They play an irreplaceable and important role in people's daily life. [0003] Wild sumac mainly refers to a class of plants belonging to the family Anacardiaceae and the genus Toxicodendron. There are more than 20 species of lacquer, distributed in eastern Asia and North America to Central America. There are 15 species in China, mainly T. vernicifluum (Stokes), T. s...
