Embodiment 1

[0039] The existing common plastic tablecloth is not environmentally friendly enough, easy to have peculiar smell, and is not durable enough. The present invention proposes the material of antibacterial plastic tablecloth, and the produced tablecloth can improve the environmental protection performance, insect resistance, water resistance, oil resistance and resistance of the tablecloth. Chemical performance, safety in use, durability and dimensional stability, reduced odor, and improved stain resistance of tablecloths. And it can be made of recycled plastic, which is low cost and more environmentally friendly.

[0040] Existing living plastics, the main types are polyethylene, polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS, ABS), polyamide, etc., which are mixed with various adhesives, coatings, etc. In the existing technology, various plastics can be directly separated before they can be produced. The process is complicated and the cost is high.

Embodiment 2

[0066] A method for manufacturing an antibacterial plastic tablecloth material, the steps of which are as follows:

[0067] (1) Pulverize the diatomite into a particle size of 1000-1500, put it into a single-screw extruder, add sodium hexametaphosphate and sodium lignosulfonate, set the screw speed to 150-200r / min, and the extruding temperature of 100-120℃, then add the insect repellant, the insect repellant is the medicinal residue, the medicinal residue is composed of asparagus, fangji and raw ground, and the mass ratio of the residues of asparagus, fangji and raw ground is 8:7:6, extrusion treatment 10 min to obtain surface-modified diatomite powder; diatomite, sodium hexametaphosphate, sodium lignosulfonate, and insect repellent, in a mass ratio of 2:0.5:0.7:1.

[0068] (2) put the surface-modified diatomite powder obtained in step (1) into the reactor, add water and stir to form a dispersion, add aluminum glycinate and vinyl acetate, mix and stir, and then add azobisisobu...

Embodiment 3

[0078] A method for manufacturing an antibacterial plastic tablecloth material, the steps of which are as follows:

[0079] (1) Pulverize the diatomite into a particle size of 1000-1500, put it into a single-screw extruder, add sodium hexametaphosphate and sodium lignosulfonate, set the screw speed to 150-200r / min, and the extruding temperature of 100-120℃, then add the insect repellant, the insect repellant is the dregs, the dregs are composed of asparagus, fangji and raw ground. Treat for 10 min to obtain surface-modified diatomite powder; the mass ratio of diatomite, sodium hexametaphosphate, sodium lignosulfonate, and insect repellent is 2:0.4:0.7:1.

[0080] (2) put the surface-modified diatomite powder obtained in step (1) into the reactor, add water and stir to form a dispersion, add aluminum glycinate and vinyl acetate, mix and stir, and then add azobisisobutyramidine hydrochloride , stir evenly, stir and react at 80-100 ℃ for 50 minutes, send it to a high-energy ball...

Abstract

The invention discloses a preparation method of an antibacterial composite tablecloth with a cotton substrate, belongs to the field of tablecloth preparation and aims at the problems of poor antibacterial effect, high cost and complicated preparation process in the prior art. The preparation method of the antibacterial composite tablecloth with the cotton substrate comprises the following steps: (1) diatomite is modified, surface modified diatomite powder is obtained, and decoction dregs are added to serve as an insect-resisting agent; (2) surface modified diatomite powder is obtained by processing for standby application; (3) existing plastic is fed into a chopper for chopping; (4) chopped plastic chips are subjected to hot melting in multi-section hot melting equipment; (5) a heat stabilizer, a chlorinated polyethylene auxiliary and a composite additive are added to the plastic subjected to hot melting; (6) the surface modified diatomite powder is mixed with plastic granules, the mixture is processed by an extruder, a product is fed into rolling equipment, and a corresponding face film is obtained; (7) the obtained face film is subjected to press-fitting with bottom-surface cotton cloth prepared in an antibacterial manner, then embossing, cooling and rolling are performed, and the corresponding composite tablecloth is obtained. The effects that process and preparation are simple and the antibacterial effect is good can be realized.

Description

technical field [0001] The invention relates to the field of tablecloth manufacturing, and more particularly, to a method for manufacturing an antibacterial cotton substrate composite tablecloth. Background technique [0002] Practical tablecloths pay attention to their functions. Generally, the material is mainly plastic, and the color is relatively simple. As the quality of the dining table is getting higher and higher, many families generally do not use tablecloths, but only need to cover a layer of plastic tablecloths. The practical tablecloths are mainly made of plastic, and this tablecloth is not like the traditional plastic tablecloth color. Too single, dull, with various colors and patterns, easy to match with a variety of decoration styles, it is a good choice for soft decoration. This tablecloth is stain resistant, easy to clean and easy to carry. It has a long service life and is not easy to fade or fade. Tablecloths have been very popular in Europe and the Unit...
