Embodiment 1

[0034] The existing ordinary plastic tablecloths are not environmentally friendly, easy to smell, and not durable enough. The present invention proposes antibacterial plastic tablecloth materials. Chemical performance, use safety, durability and dimensional stability, reduce odor and also improve stain resistance of tablecloths. And it can be made by recycling domestic plastics, which has low cost and is more environmentally friendly.

[0035] The main types of existing living plastics are polyethylene, polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS, ABS), polyamide, etc., which are mixed with various adhesives, coatings, etc. Among them, the existing technology directly separates various plastics before making them, which is complicated in process and high in cost.

[0036] This scheme directly selects cheap living plastics to decompose and then mixes the plastics, and adds antibacterial agents to obtain the required antibacterial properties. The process used ...

Embodiment 2

[0052] A method for manufacturing an antibacterial plastic tablecloth material, the steps are as follows:

[0053] (1) The existing plastic is fed into the shredder for shredding, and the particle size is shredded to 1-15mm;

[0054] (2) Melt the chopped plastic fragments in a multi-stage hot-melt equipment; the temperature curve is 0-90°C, 10min; 90-180°C, 25min; 180-240°C, 25min; 240-360°C, 20min . Since there are many types of plastics in garbage recycling plastics, and because different types of plastics have different temperatures and effects, the following temperatures respectively act on the following, 0-90°C; soften plastics; 90-180°C; polyethylene , polypropylene is melted; separation; 180-240; polyvinyl chloride, polystyrene, are melted; separation; 240-360 ° C, polyamide is melted; four-stage melting avoids different high temperatures leading to low-temperature plastic cracking , resulting in instability and modification. After each section of plastic is melted, ...

Embodiment 3

[0061] A method for manufacturing an antibacterial plastic tablecloth material, the steps are as follows:

[0062] (1) The existing plastic is fed into the shredder for shredding, and the particle size is shredded to 1-15mm;

[0063] (2) Melt the chopped plastic fragments in a multi-stage hot-melt equipment; the temperature curve is 0-90°C, 10min; 90-180°C, 25min; 180-240°C, 25min; 240-360°C, 20min . Since there are many types of plastics in garbage recycling plastics, and because different types of plastics have different temperatures and effects, the following temperatures respectively act on the following, 0-90°C; soften plastics; 90-180°C; polyethylene , polypropylene is melted; separation; 180-240; polyvinyl chloride, polystyrene, are melted; separation; 240-360 ° C, polyamide is melted; four-stage melting avoids different high temperatures leading to low-temperature plastic cracking , resulting in instability and modification.

Abstract

The invention discloses a manufacturing method of antibacterial plastic tablecloth, and belongs to the field of tablecloth material preparation. In view of the problems of poor antibacterial effect, high cost and complex manufacturing technology existing in the prior art, the invention provides the manufacturing method of an antibacterial plastic tablecloth material. The method comprises the steps: (1) sending existing plastics to a chopper and chopping, and chopping to the granularity of 1-15 mm; (2) allowing the chopped plastic fragments into a multi-section hot-melting device, and carryingout hot melting; (3) adding a heat stabilizer, a chlorinated polyethylene auxiliary agent and a compound additive into the hot-melt plastics with a mass ratio of 3:(1-3):2, wherein the total mass of the three components is 10%-15% of the mass of the part of the plastics; (4) sending the plastics of the step 3 into a hot-melting machine and melting, allowing the molten plastics to pass through an extruder, and then sending into a calendar device, to obtain a corresponding tablecloth film; and (5) embossing, cooling and rewinding the obtained film, to obtain the corresponding tablecloth. The method can achieve the effects of simple process, good antibacterial effect and simple manufacturing.

Description

technical field [0001] The invention relates to the field of making tablecloth materials, more specifically, to a method for manufacturing an antibacterial plastic tablecloth. Background technique [0002] Practical tablecloths pay attention to their functions, and the general material is mainly plastic, and the color is relatively single. As the quality of dining tables is getting higher and higher, many families generally do not use tablecloths, and only need to spread a layer of plastic tablecloths. Too single, dull, with various colors and patterns, easy to match with various decoration styles, it is a good choice for soft decoration. This tablecloth is stain-resistant, easy to clean and easy to carry. Long service life, not easy to fade and fade. Tablecloths were very popular in European and American countries. In recent years, due to the hot weather in Japan and Southeast Asian countries, plastic tablecloths have also become popular in these countries. Families are ...
