Problems solved by technology

However, the existing fresh-keeping containers are usually kept fresh at room temperature. If it encounters summer and the climate is hot, it is extremely easy to cause corrosion and lose its original flavor. Therefore, the fresh-keeping period is not long
In order to prolong the fresh-keeping period, some fresh-keeping containers with good thermal insulation performance of the container itself have also been developed in the prior art, such as fresh-keeping containers made of ceramics as materials, but the air permeability of t

preparation Embodiment 1

[0078] This example is used to illustrate the preparation of the waterproof and breathable particles provided by the present invention.

[0079] 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 waterproof and air-permeable particles, calculated by weighing method, based on the total weight of the waterproof and air-permeable particles, The content of the coating layer was 6% by weight.

preparation Embodiment 2

[0081] This example is used to illustrate the preparation of the waterproof and breathable particles provided by the present invention.

[0082] 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 Coating on the surface of quartz sand particles; then, cooling to room temperature, crushing and sieving to obtain waterproof and air-permeable particles, by weighing method, calculate, based on the total weight of waterproof and air-permeable particles, the content of the coating layer of hydrophobic substances is 4.3% by weight.

preparation Embodiment 3

[0084] This example is used to illustrate the preparation of the waterproof and breathable particles provided by the present invention.

[0085] 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 solid curing agent, stir evenly, so that polyurethane resin is coated on the surface of quartz sand and glass beads; then, cool to room temperature, break and sieve to obtain waterproof and breathable particles. Based on the total weight of the granules, the content of the hydrophobic substance coating is 2.2% by weight.

Abstract

The invention provides a splicing container for retaining freshness. The container for retaining freshness comprises a container body for retaining freshness and a container cover matching with each other. The container body for retaining freshness comprises a bottom surface and a side wall. The side wall is of a double-layer structure with an inner side wall and an outer side wall. The inner side wall, the outer side wall and the bottom surface form a cavity for containing thermal insulation materials. The inner layer side wall is formed by splicing inner-layer boards for retaining freshness, and the outer side wall is formed by splicing outer-layer boards for retaining freshness. The inner-layer boards for retaining freshness, the outer-layer boards for retaining freshness and the bottom surface are all spliced to form the container body for retaining freshness. The inner-layer boards for retaining freshness, the outer-layer boards for retaining freshness and the container cover are all formed by waterproof and breathable particles and hydrophobic bonder by means of bonding and curing. Gaps through which gaseous molecules can permeate but liquid water molecules cannot permeate are formed between adjacent waterproof and breathable particles. The splicing container for retaining freshness can be installed in the field as required by the scale and has a good food freshness retaining effect.

Description

technical field [0001] The invention belongs to the field of food preservation, and in particular relates to a large splicable fresh-keeping container suitable for on-site installation. Background technique [0002] With the improvement of people's living standards, residents put forward higher requirements for the freshness of food, especially vegetables, fruits and meat, and simple fresh-keeping containers widely used for food preservation have become a must for people's daily use at home. It is not only convenient and practical, but also can store food in different categories. Most of the existing daily fresh-keeping containers are dense and uniform films made of polyethylene homopolymer, which have good transparency, mechanical properties, toughness and elasticity, and are impermeable to gas and water vapor, which can well prevent water vapor The distribution can play a certain fresh-keeping effect. But existing fresh-keeping container is to keep fresh at normal temper...
