Heat-insulating and heat-preserving flower pot for planting plants and manufacturing method thereof

Abstract

The invention discloses a heat-insulated flowerpot for planting plants. The flowerpot includes a pot body for storing nutrient soil required for planting plants, and a pot cover arranged at the upper edge of the pot body. The pot cover is a For the cover that can be opened and closed, the two covers are connected to the upper edge of the basin body through hinges; the basin body is composed of an acrylic layer, a perlite mixed resin layer and an FRP fiber layer from the outside to the inside, and the acrylic layer is mixed with the perlite. There is an adhesive layer between the resin layers and between the perlite mixed resin layer and the FRP fiber layer to prevent the two layers from falling off and separating; the thickness of the acrylic layer is 0.5 to 2.5mm, and the perlite mixed resin layer The thickness of the layer is 20~30mm, and the thickness of the FRP fiber layer is 0.5~2.5mm. The invention uses expanded perlite ceramsite with closed pores on the surface as the insulation material to produce a product with light weight and good thermal insulation effect. At the same time, the invention also provides a manufacturing method for preparing and using surface closed-pore expanded perlite ceramsite to manufacture heat-insulating flowerpots.

Description

technical field [0001] The invention relates to the technical field of flower pot manufacturing, in particular to a flower pot using expanded perlite as a thermal insulation material for thermal insulation of planted flowers and plants and a manufacturing method thereof. Background technique [0002] A flowerpot is a container for planting flowers and bonsai plants, which is generally in the shape of a rounded platform or a chamfered platform with a large mouth and a small bottom. Conventional flower pots can only meet the needs of bonsai plants growing under normal conditions with suitable ambient temperature, and for some plants that require temperature, it is necessary to heat and insulate the flower pots where the plants are planted. The usual method is , transport the flower pots with plants to the greenhouse for cultivation in cold weather, and move the flower pots with plants to a cool place in too hot weather, which not only increases the labor intensity, but also co...

Conventional flower pots can only meet the needs of bonsai plants growing under normal conditions with suitable ambient temperature, and for some plants that require temperature, it is necessary to heat and insulate the flower pots where the plants are planted. The usual method is , transport the flower pots with plants to the greenhouse for cultivation in cold weather, and move the flower pots with plants to a cool place in too hot weather, which not only increases the labor intensity, but also conventional Flowerpots made of ceramics are usually heavy in weight and difficult to carry. Moreover, for ordinary farmers, they often lack the hardware settings of greenhouses, resulting in the death of some plants with poor cold resistance in the cold winter season, or causing Some plants with poor heat tolerance will affect their growth due to the heat of their roots

In addition, although some bonsai plants are resistant to cold, they still need to be kept warm in cold weather. The roots and leaves of potted plants are frostbitten and affect the growth of plants, and even cause irreversible frostbite to the roots of plants and cause plant death

[0003] Expanded perlite is made of natural perlite ore as a raw material, which is porous and white granular material obtained by screening and high-temperature calcination. It has light weight, low thermal conductivity (0.05 0.15cal / m·h·℃), chemical stability Good (pH=7), non-toxic, odorless, anti-corrosion and other advantages, has been widely used in new construction, furniture decoration, petrochemical and high-grade coatings and other industries, but the existing expanded perlite is hydrophilic and causes The problem of easy water, its water absorption rate is as high as 800%, which makes the thermal insulation performance of expanded perlite products greatly reduced during use, and also causes problems such as cracking of expanded perlite products

Moreover, the traditional preparation process of expanded perlite ceramsite with closed cells on the surface is usually in the process of granulation, first processing the powdery ingredients into a small ball less than 0.5 mm, and then spraying the prepared mist aqueous solution on the The surface of the pellets in the running granulator, and then sprinkle the powdery ingredients on the surface of the wet pellets, after repeated spraying of the mist solution and sprinkle the powdery ingredients on the surface of the wet pellets, after Layer after layer of wrapping, the volume of the small ball continues to increase, and finally the whole process of granulation is completed, and a spherical ceramsite with relatively high strength is prepared. During the roasting process, the interior of the spherical attapulgite flower ceramsite is very large. It is difficult to completely burn through, which directly affects the internal quality of the spherical attapulgite flower ceramsite, making it difficult to meet the needs of heat insulation materials for flower pots

In addition, there are also flower pots with plants on the market. The expanded perlite treated with the shell can greatly improve its strength waterproof rate and closed cell rate, but its thermal conductivity will increase accordingly, resulting in perlite insulation. The effect is significantly worse, which makes it difficult for shell-coated expanded perlite to meet the needs of heat insulation materials for flower pots

Later, a kind of vitrified micro-pearlite that uses electricity to expand at high temperature appeared on the market. It has high waterproof, closed-cell capabilities, and high strength, but its processing consumes too much power, especially Its glazed surface is not easy to bond, which is not conducive to vitrified microbead perlite as a heat insulation material for flowerpots
