Embodiment 1

[0032]

[0033] First, weigh the coffee grounds, and stir the coffee grounds through a high-speed mixer to remove water. The temperature of the high-speed mixer is set at 110 ° C. After the temperature reaches 15 minutes, the weighed interface modifier is added to stir and mix. The fixed stirring time is 10 minutes; then, the moisture content of the polylactic acid resin needs to be reduced to below 0.05-0.1% during the processing; The material was stirred for 10 minutes with a single-shaft mixing bucket, and the weighed polyvinyl acetate resin, lubricant, impact modifier and inorganic filler were stirred for 10 minutes with a single-shaft mixing bucket; the above mixtures were respectively added to the twin-screw extruder Melt extrusion granulation in the machine.

Abstract

The invention provides a biodegradable coffee grounds composite material and its products. The composite material is directly made of coffee grounds through surface treatment and then added with biodegradable materials, and then modified to make biodegradable coffee grounds composite materials. Material. The molded products of the composite material are widely used in the film industry, such as disposable garbage bags, food packaging bags or films used in agriculture, thus solving the problem that coffee grounds can only be used in low-level applications.

Description

【Technical field】 [0001] The invention belongs to the technical field of materials, and in particular relates to a biodegradable coffee grounds composite material and a product thereof. 【Background technique】 [0002] With the increasing awareness of environmental protection, biodegradable environmentally friendly plastics are increasingly valued by the public. In addition to the improvement of performance, it tends to develop materials and products with high added value. [0003] In view of the coffee food culture in the global market, the daily coffee grounds are increasing day by day. Although there are many uses of this biomass material, they are also used in low-level applications. For example, currently in the market, coffee grounds have been treated with high temperature to form coffee carbon, which has been applied in textile-related fields. [0004] In view of this, it is necessary to develop a biodegradable coffee grounds composite material and its products to so...
