AI Technical Summary

Benefits of technology

This patented technology improves how well an optically transparent plastic looks on its own without losing any strength or being too expensive for others to use them over time. It also has good abrasion resistant qualities with high impact resistance against damage from external factors such as rain water.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the durability of reflective film lamps that utilizes traditional prism sheet designs with poor mechanical properties for safety purposes. This results from their compositions being too soft at room temperature making them easier to break off when shipped over long distances without causing harm themselves.

preparation example Construction

[0014] The preparation method of the above wear-resistant optical material comprises the following steps: weighing 66-70 parts of polyurethane acrylate, 20-40 parts of polypropylene, 10-30 parts of chopped glass fiber, 2 parts of dimethyl itaconate ~3 parts, 1~2 parts of lubricant, 2~6 parts of photoinitiator are placed in the container, and heated to 40~50℃, stirred and dispersed at constant temperature for 2~3h, then cooled to room temperature, and then the material is ground to 400~500 Mesh fine powder, that is.

[0015] The wear-resistant optical material of the present invention can effectively enhance the wear resistance of the optical material while ensuring that other mechanical properties of the material do not decrease and the production cost is low; the wear-resistant optical material prepared by the present invention is firm and tough, and the surface Not easy to wear, strong environmental corrosion resistance, not easy to rust, durable.

Embodiment 1

[0017] Weigh 66 parts of polyurethane acrylate, 20 parts of polypropylene, 10 parts of alkali-free glass fiber, 2 parts of dimethyl itaconate, 1 part of lubricant, and 2 parts of 1-hydroxycyclohexyl phenyl ketone by weight. Put it in a container, and heat it to 40°C, stir and disperse at a constant temperature for 2 hours, then cool to room temperature, and then grind the material into a 400-mesh fine powder.

Embodiment 2

[0019] Weigh 67 parts by weight of polyurethane acrylate, 25 parts of polypropylene, 15 parts of alkali-free glass fiber, 2 parts of dimethyl itaconate, 1 part of lubricant, 2-hydroxy-2-methyl-1-benzene Put 3 parts of diethyl acetone in a container, heat to 43°C, stir and disperse at a constant temperature for 2.5 hours, then cool to room temperature, and then grind the material into a 430-mesh fine powder to obtain the final product.

Abstract

The invention discloses an abrasion-resistant optical material. The optical material comprises the following components in parts by weight: 66-70 parts of urethane acrylate, 20-40 parts of polypropylene, 10-30 parts of chopped glass fibers, 2-3 parts of dimethyl itaconate, 1-2 parts of a lubricant and 2-6 parts of a photoinitiator. According to the abrasion-resistant optical material, the abrasionresistance of the optical material can be effectively reinforced under the condition that other mechanical performance of the material is not reduced and the manufacture cost is relatively low; and the abrasion-resistant optical material prepared by the method has the advantages of an abrasion-resistant surface, strong environmental corrosion resistance, corrosion prevention and durability.
