Environment-friendly cork compound material, adhesion agent and preparation method for products thereof

Abstract

The invention discloses an environment-friendly cork compound material, an adhesion agent and a preparation method for products thereof. After the adhesion agent for the environment-friendly cork compound material is prepared, the adhesion agent is applied to the cork compound material and the products thereof. The environment-friendly cork compound material comprises a cork waste material, a natural plant fiber, the adhesion agent and an essence, wherein the cork waste material is a red wine cork recycling material. The preparation method for the products of the environment-friendly cork compound material comprises the following steps: a, crushing a red wine cork; b, mixing all the raw materials of the compound material; c, split-charging the fully mixed raw materials; and d, completely pouring the mixed raw materials in an utensil into a cavity of a mould for the required products, and hotly pressing and shaping. The products made of the cork compound material are environment-friendly and non-toxic, has the effects of antibiosis, mildew resistance, anti-oxidation, and the like, and meanwhile has an excellent mechanical property.

Description

technical field [0001] The invention relates to the technology in the field of composite materials, in particular to an environment-friendly cork composite material and a preparation method of its products. Background technique [0002] Existing cork products are mainly made of the bark of the cork oak that grows in the Mediterranean coast and the Qinling area of ​​China. The bark material is picked every 7 to 9 years. Due to its special growth environment and long harvesting period , so the annual output is only about 370,000 tons, of which Portugal has the highest output, accounting for more than half of the world's output. [0003] Existing cork products basically process the entire piece of material by mechanical or manual methods, resulting in a waste of 20-30% of cork scraps; in addition, manual processing takes a long time and costs high, so it makes all kinds of cork products invisible. Become a consumer product at the top of the pyramid. [0004] In view of the ex...

Problems solved by technology

[0005]On the one hand, cork products made of benzophenone solvents as adhesives are harmful to human health. It will lead to the deterioration of the solution, which will cause great harm to the human body after drinking; on the other hand, extrusion molding takes a long time and the output is limited, which often cannot meet the needs of subsequent processing; the extrusion molding block also needs mechanical or manual processing, and cannot be molded at one time ;The products formed by extrusion have poor mechanical properties, no waterproof, mildew-proof and anti-bacterial effects, and have been unable to meet people's high-quality and environmental protection requirements for cork composite products.
