Abstract

The invention provides a zero formaldehyde ecological board and a manufacturing technology thereof. The waterborne zero formaldehyde ecological board comprises two pieces of facing paper, balancing paper and a fiber board body. The two pieces of facing paper are located on the upper surface layer and the lower surface layer correspondingly, the balancing paper and the fiber board body which are sequentially alternated are arranged between the two pieces of facing paper, and the two pieces of facing paper are adhered to the adjacent balancing paper correspondingly; and the outer surface layers of the two pieces of facing paper are each provided with a first waterborne polyurethane layer, the balancing paper is adhered to the two pieces of facing paper through second waterborne polyurethane layers correspondingly, and the balancing paper is adhered to fiber board body through third waterborne polyurethane layers. According to the zero formaldehyde ecological board and the manufacturing technology thereof, environment-friendly waterborne polyurethane layers are adopted, and therefore the formaldehyde density of the ecological board can be released to be 0.1 mg / L or below; and the manufacturing technology of the ecological board is simplified, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of ecological board production technology, and specifically discloses a water-based zero-formaldehyde ecological board and a manufacturing technology thereof. Background technique [0002] With the continuous improvement of the level of science and technology and living standards, ecological panels, as interior decoration materials, are becoming more and more popular among the people. Ecological board has the characteristics of high temperature resistance, acid and alkali resistance, moisture resistance, fire prevention, etc. The surface is not easy to change color and peel, and it is easy to process into veneers with different styles and strong texture. Since its birth, this board has been rapidly used in furniture and floors. and interior decoration. At the same time, as a new type of product, this product combines the functions of veneer and plywood into one. While saving the production process, it improves the ad...
