Problems solved by technology

Although the starch used in this invention can disintegrate the polypropylene modified material into pieces to a certain extent, fillers such as talcum powder and mica reduce the consumption of polypropylene to a certain extent and achieve the purpose of reducing costs, but due to the spunbonded polypropylene The proportion of special materials is much higher than that of starch, so in fact, the product still cannot be naturally degraded through composting

Embodiment 1- Embodiment 6

[0047] The invention provides a plant-based biodegradable nonwoven fabric, which is composed of a biodegradable polymer, a plant-based powder, a plasticizer, a coupling agent, a stabilizer and a lubricant. Wherein said each composition and consumption are as shown in Table 1.

[0048] Table I

[0049]

[0050] The manufacturing method of the above-mentioned plant-based biodegradable non-woven fabric comprises the following steps:

[0051] (1) Put the plant-based powder, coupling agent, plasticizer, stabilizer and lubricant into the high-mixing unit for blending, at a temperature of 100-120°C, after 9-11 minutes of high-mixing, put in the lubricant and stabilizer mix;

[0052] (2) Put the mixture obtained in step (1) into the cold mixing unit, add biodegradable polymers for cold mixing, and take it out after 9 to 11 minutes of cold mixing;

[0053] (3) adding the mixture obtained in step (2) to twin-screw granulation to prepare pellets;

[0054] (4) Put the pellets obtai...

Abstract

The invention discloses a plant-based biodegradable non-woven fabric. The plant-based biodegradable non-woven fabric is made from 40-80 parts of biodegradable polymers, 20-50 parts of plant-based powder, 3-8 parts of plasticizer, 1-3 parts of coupling agent, 0.5-3 parts of stabilizer and 1-5 parts of lubricant. The plant-based biodegradable non-woven fabric adopts the cheap plant-based powder and materials of other biodegradable polymers for blending, the obtained product has good elasticity and mechanical strength and the flexible performance of cloth, the cost can be greatly reduced, and compared with a traditional polypropylene non-woven fabric, the plant-based biodegradable non-woven fabric has excellent environmental friendliness.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a plant-based biodegradable non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric) is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is widely used in many fields such as diapers, surgical gowns, shopping bags, clothing accessories and disposable daily products due to its richness, low price and recyclability. [0003] Due to the low cost and wide application of non-woven fabrics, and they are mostly used in disposable products, people usually treat non-woven fabrics in a disposable way. However, most of the non-woven fabrics currently on the market are made of polypropylene and polypropylene filaments. If the waste non-woven fabrics are disposed of by incineration, it will cause air pollution; while landfill treatment is difficult to decompose ...
