preparation example Construction

[0032] The preparation method of the environment-friendly wooden anti-glare board of the present invention comprises the following steps:

[0033] S100: Dip the wooden veneer into an impregnating agent to impregnate the wooden veneer, the weight ratio of the weight of the wooden veneer before the impregnation to the weight of the wooden veneer after the impregnation is 1:1.2-1.4;

[0034] S200: Arrange and stack a plurality of impregnated wooden veneers and perform hot pressing treatment to obtain the environmentally friendly wooden anti-glare board. The hot pressing temperature of the hot pressing treatment is 130°C-180°C, and the hot pressing time is 15min~30min, hot pressing pressure is 2.5~4.5MPa;

[0035] Wherein the impregnating agent used in the impregnating treatment comprises water and phenolic resin, wherein the weight ratio of the water and the phenolic resin is 1:1-3.

[0036] The environmentally friendly wooden anti-glare board of the present invention is made by...

Embodiment 1

[0054] S110: first place the eucalyptus veneer in a closed drying kiln at 120°C for 8 hours;

[0055] S120: Immerse the dried eucalyptus veneer in the impregnating agent to below the liquid level for 3 hours; the impregnating agent in this embodiment is a mixture of water and phenolic resin, wherein the ratio of water to the phenolic resin in parts by weight is 1:1;

Abstract

The invention provides an environmental-friendly wooden anti-glare plate and a manufacturing method thereof, wherein the manufacturing method comprises following steps: immersing wooden single plates into an impregnating agent for immerse processing and the weight ratio between the weight of the wooden single plates before the immerse processing and the weight of the wooden single plates after the immerse process is 1:1.2 to 1.4; processing the sequentially stacked wooden single plates with heat-press after the plurality of the wooden single plates are immersed; the impregnating agent comprises water and phenolic resin; and the weight part ratio of the water and the phenolic resin is 1:1 to 3. The environmental-friendly wooden anti-glare plate provided herein has the advantages of light weight, high strength, strong aging resistance and acid and alkali corrosion resistance; the environmental-friendly wooden anti-glare plate can be used to effectively replace an anti-glare plate on an expressway, thus the problems of poor aging-resistance performance of the anti-glare plate and secondary damage in a car accident; the running efficiency of expressways in our country is improved; the maintenance and running cost are reduced, thus the expressways can be ran with low carbon, safety, high efficiency and low cost; and the sustainable development of the expressways is promoted.

Description

technical field [0001] The invention relates to the technical field of road maintenance materials, in particular to an environmentally friendly wooden anti-glare board and a preparation method thereof. Background technique [0002] The "Twelfth Five-Year Plan for Transportation Development" pointed out that by 2015, the total mileage of expressways in my country will reach 108,000 kilometers, surpassing the 92,000 kilometers of the United States. my country has built the largest expressway system in the world. Compared with the rapid development of expressways, the ancillary facilities of expressways in my country are still relatively backward, and their performance needs to be improved and perfected urgently. As one of the important materials for the construction of highway safety facilities, anti-glare panels have been used in China for nearly 20 years. At present, the consumption of anti-glare panels in my country ranks first in the world. The development level of anti-...
