However, in this method, materials with better hydrophilicity and materials with poorer hydrophilicity are mixed, and the surface hydrophilicity of the foamed material obtained is difficult to surpass the added raw materials with good hydrophilicity, and the effect of improving hydrophilicity is relatively low. Low, the effect is not significant, and it is not enough to meet the needs of production and life
Therefore, the foaming material in the prior art has the problem of poor hydrophilicity

Abstract
The invention discloses a surface treatment method of a foaming material and relates to the technical field of surface treatment. An existing foaming material has the defect of poor hydrophilicity. The surface treatment method is technically characterized by comprising the steps: material feeding, wherein the foaming material is placedin a closed processing bin; plasma treatment, wherein the two sides of the foaming material are separately provided with an electrode, argon and oxygen are injected into the processing bin, alternating current with the working frequency of 10 MHz is introduced into the two electrodes, the alternating current electric power is greater than 150 W but does not exceed 5000 W, the argon and the oxygen obtain energy in an electric field generated by the two electrodes and form plasma, and the plasma moves with the change of the electric field and collides with the foaming material, so that chemical bonds of polymers on the surface of the foaming material breakand free radicals are formed; the free radicals react with oxygen to form hydrophilic oxygen-containing groups. The surface is uneven, the surface area is increased, the activity of the surface molecular groups can be enhanced, and the advantage of better surface hydrophilicity is achieved, so that the foaming material is convenient to use.
Description
technical field [0001] The invention relates to the technical field of surface treatment, in particular to a method for surface treatment of foamed materials. Background technique [0002] The surface hydrophilicity of a material refers to the property that the surface of a material is wetted by water. Materials with good hydrophilicity have a greater affinity for water, are more likely to absorb water, and are more likely to be wetted by water. Materials with good hydrophilicity can be widely used in various fields. Most of the foaming materials on the market, in order to obtain better hydrophilicity, usually change the properties of the foaming material and improve the surface hydrophilicity of the foaming material by changing the raw materials added during production and the ratio of raw materials. For example, raw materials with good hydrophilicity are added to improve the surface hydrophilicity of the foamed material after the finished product is made. However, in thi...
