preparation example Construction

[0025] The preparation method of multifunctional coffee grounds composite imitation rattan material of the present invention is as follows:

[0026] (1) Treatment of coffee grounds: wash the coffee grounds with distilled water, filter and dry; place the dried coffee grounds in a grinder for grinding to obtain coffee grounds powder with a particle size of 1 to 5 microns;

[0027] (2) Preparation of coffee charcoal: Take a certain amount of coffee grounds powder obtained in step (1) and heat it at 50°C min under a nitrogen atmosphere. -1 Heating to 460°C at a high speed, roasting for 2 hours to obtain coffee charcoal, and putting the coffee charcoal in a grinder for grinding to obtain a powder with a particle size of nanometer scale;

[0028] (3) Mixing of coffee grounds and coffee charcoal: the coffee charcoal powder obtained in step (2) is soaked in a mixed solution of concentrated sulfuric acid and concentrated nitric acid with a volume ratio of 3:1, heated by microwave at 30...

Embodiment 1-16

[0033] The following examples adopt the above method to prepare rattan-like materials.

[0034] Its mass ratio and rattan-like material performance test are as follows:

[0035] Table 1

[0036]

[0037]

[0038] Result: From the analysis in Table 1, it can be seen from Examples 2 to 13 that with the increase of the added amount of coffee grounds and coffee charcoal, the tensile strength and elongation at break of the product all decreased; With the increase of ethylene and styrene-butadiene rubber proportion, the tensile strength and elongation at break of the product all increase thereupon, and the flame retardancy also increases thereupon; wherein, in embodiment 14 and embodiment 15, the tensile strength of the product and There is an obvious positive correlation between the elongation at break and the change of the styrene-butadiene rubber content; in Example 16, the flame retardant is reduced, and the flame retardant performance of the product is also reduced. Whi...

Abstract

The invention relates to a multifunctional coffee grounds composite rattan-imitating material and application thereof. The multifunctional coffee grounds composite rattan-imitating material is prepared taking coffee grounds powder, coffee carbon powder, polyvinyl chloride, rubber type chlorinated polyethylene and butadiene styrene rubber as raw materials. Lots of waste residues generated in the coffee industry are effectively utilized; meanwhile, by utilizing the characteristics of the coffee grounds, the smell and texture of the rattan-imitating material are effectively improved, a large number of substances with high heat resistance and oxidation resistance contained in the coffee grounds are utilized to replace an antioxidant of the rattan-imitating material, the antioxidant performanceof the rattan-imitating material is guaranteed, meanwhile, the addition amount of the antioxidant is reduced, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of new rattan weaving materials, and in particular relates to a coffee grounds composite rattan-like material. Background technique [0002] As a traditional handicraft, all kinds of handicrafts, furniture and daily necessities made of rattan materials are healthy, environmentally friendly, natural and fresh, with a classic and elegant atmosphere. Traditional rattan weaving materials generally use the skin and core of vine stems. Although it is pure natural and has a fresh smell, it is easy to corrode, mildew, and insects. It will deform after absorbing a certain amount of water. Now it has been gradually replaced by imitation rattan materials. . Most of the existing rattan-like materials are PE rattan and PVC rattan. Compared with natural rattan, it has the advantages of mildew resistance, moth resistance, hygiene, and easy cleaning. However, when it is used, it often has a persistent plastic smell and has...
