Problems solved by technology

[0002] Many of the existing paints used on the surface of wooden floors are not wear-resistant and hard enough, which leads to the fact that after the wooden floor is paved, it is easy to wear the paint when stepping on it, which affects the overall aesthetic feeling; in order to overcome this problem, some The coating amount of the paint is enlarged to increase the wear resistance and hardness, which will lead to an increase in the overall cost
There are also some hard powders added to the paint, but this approach often leads to blurred boards after painting

Abstract

The invention discloses an ultraviolet wear resistant primer and a preparation method thereof. The ultraviolet wear resistant primer comprises the following components in parts by weight: 55-75 of urethane acrylate, 10-20 of tripropylene glycol diacrylate, 5-15 of trimethylolpropane triacrylate, 1-5 of photoinitiator, 10-40 of aluminum oxide and 0.5-3 of fumed silica. The preparation method provided by the invention comprises the following steps of: firstly mixing, dissolving and stirring the tripropylene glycol diacrylate and the trimethylolpropane triacrylate, then adding the photoinitiator and stirring, adding the urethane acrylate for blending and stirring, adding the fumed silica and the aluminum oxide while stirring, stirring for 10-20 minutes after addition, resting for 1-2h, and filtering by using a filter screen to obtain the ultraviolet wear resistant primer. The ultraviolet wear resistant primer provided by the invention has good wear-resistant performance and high hardness; after wood floors are coated by the ultraviolet wear resistant primer, and the wood floors have good whole definition; and the formula is simple and reasonable. The preparation method provided by the invention has the advantages that the technology is simple and the processing is convenient.

Description

technical field [0001] The invention relates to a UV wear-resistant primer, and also relates to a method for preparing the UV wear-resistant primer. Background technique [0002] Many of the existing paints used on the surface of wooden floors are not wear-resistant and hard enough, which leads to the fact that after the wooden floor is paved, it is easy to wear the paint when stepping on it, which affects the overall aesthetic feeling; in order to overcome this problem, some The amount of paint applied is enlarged to increase wear resistance and hardness, which will lead to an increase in overall cost. There is also adding some hard powder to the paint, but this approach often leads to blurred board surface after painting. [0003] The wear-resistant primer of the present invention increases the wear resistance after painting and does not affect the overall clarity after painting. Contents of the invention [0004] The purpose of the present invention is to overcome the...
