preparation Embodiment 1

[0053] This example is used to illustrate the preparation of the film-coated first aggregate particles provided by the present invention.

[0054] Heat 100 grams of quartz sand with an average particle diameter of 0.25mm to 50°C, then add 5 grams of liquid polyvinyl alcohol tert-butyraldehyde modified epoxy resin, stir well, then add 1 gram of polyamide curing agent, and stir evenly. The epoxy resin is coated on the surface of the quartz sand; then, cooled to room temperature, crushed and sieved to obtain the coated first aggregate particles, and calculated by weighing method, the total weight of the coated first aggregate particles As a basis, the content of the hydrophobic substance coating layer was 6% by weight.

preparation Embodiment 2

[0056] This example is used to illustrate the preparation of the film-coated first aggregate particles provided by the present invention.

[0057] Heat 100 grams of ceramsite with an average particle diameter of 0.23mm to 50°C, then add 4 grams of silicone resin, stir thoroughly, then add 0.5 grams of dibutyltin dilaurate curing agent, and stir evenly to make the silicone resin Cover the surface of the quartz sand particles; then, cool to room temperature, crush and sieve to obtain the first aggregate particles of the coating, and calculate by weighing method, based on the total weight of the first aggregate particles of the coating, The content of the hydrophobic substance coating layer was 4.3% by weight.

preparation Embodiment 3

[0059] This example is used to illustrate the preparation of the film-coated first aggregate particles provided by the present invention.

[0060] Mix 50 grams of quartz sand with an average particle diameter of 0.25 mm and 50 grams of glass microspheres with an average particle diameter of 0.31 mm and heat to 50 ° C. After that, add 2 grams of liquid polyurethane resin, stir well, and then add TDI trimer 0.2 grams of body curing agent, stirred evenly, so that the polyurethane resin is coated on the surface of quartz sand and glass beads; then, cooled to room temperature, crushed and sieved to obtain the first aggregate particles coated with the coating, and calculated by weighing method , based on the total weight of the film-coated first aggregate particles, the content of the coating layer of hydrophobic substances is 2.2% by weight.

Abstract

A ventilating moisture-proof container comprises a container body and a container cover. The container body comprises a side wall and a bottom, the side wall comprises an inner layer and an outer layer, the bottom comprises an inner layer and an outer layer, the inner layer of the side wall and the inner layer of the bottom are integrated, the outer layer of the side wall and the outer layer of the bottom are integrated, cavities are reserved between the inner layer of the side wall and the outer layer of the side wall as well as between the inner layer of the bottom and the outer layer of the bottom, and the container cover is arranged on the container body and is in close fit with the outer layer of the side wall. The inner layer of the side wall and the inner layer of the bottom are formed by curing mixtures containing second particles of aggregates and second binders, and the second binders are hydrophilic binders. The outer layer of the side wall, the outer layer of the bottom and the container cover are formed by curing mixtures containing first particles of aggregates and first binders, and the first binders are hydrophobic binders. The ventilating moisture-proof container has excellent storage performance.

Description

technical field [0001] The invention relates to a breathable and moisture-proof container. Background technique [0002] With the development of society and the improvement of people's living standards, people pay more and more attention to the rationalization of diet structure, and more and more believe in what nutrition experts say "eating more whole grains is good for your health". As a part of "whole grains", rice and noodles are getting more and more attention. At present, common rice and noodle foods mainly include rice, millet, white noodles, millet noodles, corn noodles, soybeans, mung beans, and red beans. The above-mentioned rice and noodle foods are almost the necessary staple food in every family. At present, the storage methods for these rice and flour foods are relatively simple. After buying them, they are often stored in bags, cartons or jars. Rice and noodle foods stored in proper storage containers are prone to moisture or insects at room temperature, an...
