Problems solved by technology

[0007] The technical problem to be solved by the present invention: the material of the current common steel anti-glare board is mainly glass fiber reinforced plastic, which has heavy weight and high rigidity, but cannot resist erosion and damage under natural climates such as wind and snow, exposure to the sun, and acid rain. It is very prone to aging, cracking, discoloration and other phenomena, and needs to be replaced frequently, resulting in higher maintenance costs. In the event of a traffic accident, the steel anti-glare board is easy to break and cause secondary damage. A modified phenolic resin based Preparation method of anti-glare board

Abstract

The invention relates to the technical field of preparation of highway maintenance materials and particularly relates to a preparation method of a modified phenolic resin based anti-glare panel. A pine chip is taken as the raw material, a phenolic resin is taken as a matrix, a modified self-made silica sol and a glass fiber are taken as modifying agents, and snail slime, coconut oil and the like are taken as the auxiliary materials to prepare the modified phenolic resin based anti-glare panel, one part of a group in a molecule of a silane coupling agent KH-560 and a group on the surface of a silica sol particle have condensation polymerization, the other part of the group and the phenolic resin have a chemical reaction or are physically wound, then the stress of an interface between the silica sol and the chemical reaction matrix is evener, the silicon dioxide in the silica sol and the hydroxyl in the phenolic resin have a crosslinking reaction, the corrosive materials like outside water and oxygen are effectively prevented from corroding and ageing the matrix, the fatty acid in the coconut oil is adsorbed on a corroded active point to prevent further corrosion and further improvethe corrosion resistance of the anti-glare panel, and the preparation method has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of preparation of road maintenance materials, in particular to a preparation method of a modified phenolic resin-based antiglare board. Background technique [0002] With the rapid development of highway traffic in our country, especially in road sections with large traffic volume at night, if anti-glare facilities are not installed, fast-moving vehicles will easily reduce the driver's visual function or eyesight under the influence of glare from oncoming vehicles, causing troubles. dryness and discomfort, prone to traffic accidents, causing serious harm to vehicles and occupants. Therefore, the setting of anti-glare facilities is very important. [0003] The anti-glare board is a traffic safety product manufactured and installed on the central divider of the expressway to solve the glare of the opposite headlights. Most of them are set on the guardrail of the central divider of the expressway or in the mi...
