Problems solved by technology

[0002] Now the small bubble tea tea cans on the market are all made of metal cans for stamping and die-casting. After the tea cans are used, they are discarded casually, resulting in a great waste of materials, and because the metal is rusted, it is harmful to water and soil to a certain extent. certain pollution
At the same time, metal tea cans are prone to anodic oxidation reaction, which leads to a certain degree of food safety if they are in direct contact with food, and most of the small metal cans tend to be over-packaged, resulting in high packaging costs
[0003] However, current manufacturers, in order to solve ecological and environmental problems, have begun to use degradable materials to prepare tea cans, such as polycaprolactone (PCL), polylactic acid (PLA), polyesteramide (PEA), polyhydroxyalkyl polyester ( PHA), etc., can be completely degraded, but the material itself is expensive, and after being molded into a product, the temperature resistance of the product is poor, and it is easy to produce large-area deformation when it exceeds 65°C, and it is difficult to achieve secondary utilization, resulting in material and finished product damage. waste

Embodiment 1

[0050] see Figure 1-3 , A heat-resistant, degradable, environmentally friendly tea can, comprising a can body 1 and a film covering sheet 2. The top of the can body 1 is open, and a film covering groove 11 is recessed in an annular shape. 2 includes a sealing area 21 and a hand-tear area 22 extending to the periphery of the sealing area 21, the edge of the sealing area 21 is pasted on the top of the film coating groove 11; the can body 1 is made of degradable biomass The composite material is made by injection molding.

[0051] The film-covered sheet 2 includes a substrate layer 23 and a thermoplastic material layer 24 compounded on the upper surface of the substrate layer 23. The substrate layer 23 is an aluminum film layer, a polystyrene film layer, and a polyvinyl chloride film layer. The thermoplastic material layer 24 is one of a polyphenylene ether thermoplastic layer, a polypropylene thermoplastic layer, and a polyethylene thermoplastic layer; the outer surface of the ca...

Embodiment 2

[0053] The difference between this embodiment and the foregoing embodiment 1 is:

[0054] The degradable biomass composite material includes the following raw materials by weight:

[0055]

[0056] Each portion of the modified starch is prepared by the following parts by weight of raw materials:

[0057]

[0058] The starch is corn starch.

[0059] The modified starch is prepared by the following steps:

[0060] Step (1): In terms of parts by weight, stir and disperse tributyl citrate and kaolin at a speed of 400 rpm, then add polyethylene wax, stir until the mixture is milky white, and let stand for 2 minutes;

[0061] Step (2): Stir the mixture in step (1) at a rotation speed of 100 rpm, and then add starch while stirring. After the addition is complete, reduce the mixing speed to 30 rpm, and then gradually increase the temperature to 90°C, then keep warm 20min, the mixture is prepared;

[0062] Step (3): Cool the mixture prepared in step (2) to room temperature, then dry, and pulveriz...

Embodiment 3

[0070] The difference between this embodiment and the foregoing embodiment 1 is:

[0071] The degradable biomass composite material includes the following raw materials by weight:

[0072]

[0073] Each portion of the modified starch is prepared by the following parts by weight of raw materials:

[0074]

[0075] The starch is tapioca starch.

[0076] The modified starch is prepared by the following steps:

[0077] Step (1): In terms of parts by weight, stir and disperse tributyl citrate and kaolin at a rotating speed of 450 rpm, and then add polyethylene wax, stir until the mixture is milky white, and let stand for 3 minutes;

[0078] Step (2): Stir the mixture in step (1) at a rotation speed of 110 rpm, and then add starch while stirring. After the addition is complete, reduce the mixing speed to 35 rpm, and then gradually increase the temperature to 92°C, then keep warm 18min, the mixture is prepared;

[0079] Step (3): Cool the mixture prepared in step (2) to room temperature, then d...

Abstract

The invention relates to the technical field of tea caddies, in particular to a heat-resistant degradable environment-friendly tea caddy and a manufacturing technology of the heat-resistant degradable environment-friendly tea caddy. The tea caddy comprises a caddy body and a covering membrane. The top of the caddy body is open and is annularly provided with a covering membrane groove in a recessed manner. The covering membrane comprises a seal area and a hand tearing area towards the outer periphery of the seal area. The edge of the seal area is attached to the top of the covering membrane groove. The caddy body is made of degradable biomass composite by means of injection molding. The heat-resistant degradable environment-friendly tea caddy is novel in structure and good in use grip feel, the covering membrane can conduct heat seal action on the caddy body, the covering membrane is easy to tear off by means of the hand tearing area so as to open the tea caddy, and therefore the practicability is high; after being used, the heat-resistant degradable environment-friendly tea caddy can be reutilized as a planting container or a loading container or the like, so that the heat-resistant degradable environment-friendly tea caddy is environmentally friendly and high in reutilization performance; after being discarded, the heat-resistant degradable environment-friendly tea caddy can be naturally degraded within 1-6 mouths under the compost degradation conditions, and less environmental pollution is caused.
