Embodiment Construction

[0011] The production process of the present invention will be further described in conjunction with specific implementation. The percentage composition of the plastic composite material is as follows: 1-30% coffee grounds, 70-99% PLA material, 10-30% graphene oxide, 5-25% calcium carbonate , The percentage is 2-8% aminosilane coupling agent, the percentage is 1-4% binder. The main components of the plastic composite material are coffee grounds and PLA material, which are evenly stirred, dried and then granulated to form a granular composite material. The specific steps of the preparation method are as follows: put the coffee grounds in a dryer, and dry them at 70-80°C for 4-6 hours, so that the moisture content of the coffee grounds is lower than 2%; then transport them to the sieving and filtering equipment , filter the impurities, and then stir the dried coffee grounds with PLA materials, graphene oxide, calcium carbonate, aminosilane coupling agent, and binder through the...

Abstract

The invention relates to a coffee grounds-containing plastic composite material and a preparation method thereof. The composite material and the preparation method are designed to solve the technical problems of lack of products prepared from the coffee grounds and a PLA material and poor heatproof and crystallizing effects of the products prepared by like preparation methods. The plastic composite material comprises 1-30% of coffee grounds, 70-90% of the PLA material, 10-30% of graphene oxide, 5-25% of calcium carbonate, 2-8 % of an amino silane coupling agent and 1-4% of a binder. The preparation method comprises the following steps: drying the coffee grounds, stirring the dried coffee grounds, the PLA material, graphene oxide, calcium carbonate, the amino silane coupling agent and the binder, and melted, carrying out melt blending treatment and muffle furnace high-temperature rapid treatment, and drying and granulating the treated mixture; and melting the prepared granular composite material by an injection molding machine, and producing the product by using a mold temperature controller, wherein the temperature of the injection molding cylinder of the injection molding machine is divided into five ranges of temperature.

Description

technical field [0001] The invention relates to the preparation of a plastic composite material, which is a plastic composite material containing coffee grounds and a preparation method thereof. Background technique [0002] Plastic is a kind of polymer compound that is polymerized by addition polymerization or polycondensation reaction with monomer as raw material. Its main component is resin, which can be used in the preparation of containers and other products; A new material formed by optimizing the combination of material components with different properties. Coffee grounds are used in the preparation of some existing plastic materials, thereby increasing their environmental protection and recycling effects; for example, the application number 201710345003.2 disclosed in the Chinese patent literature, the application publication date is 2017.09. Plastic materials for food containers and their preparation methods”; another example is the application number 201710119310....
