Abstract
The invention relates to a surface micro-coating agent for producing pure paper and non-woven paper. The surface micro-coating agent comprises the following components: 1.25 percent to 2.5 percent of modified polyethylene emulsion with the mass concentration of 30 percent, 10 percent to 20 percent of acrylic resin with the mass concentration of 30 percent, 10 percent to 20 percent of softener with the mass concentration of 30 percent, 0.001 percent to 0.01 percent of coupling agent with the mass concentration of 30 percent, 0.001 percent to 0.01 percent of water-resistant agent with the mass concentration of 100 percent, 0.01 percent to 0.02 percent of penetrating agent with the mass concentration of 30 percent, 0.1 percent to 0.2 percent of anionic emulsifier with the mass concentration of 100 percent, a thickener of which the adding quantity ensures the viscosity of the coating agent in the range of 19 to 25s, and the balance of water. The invention also provides a preparation method of the surface micro-coating agent. According to the invention, conventional modes of adding the softener into pulp and coating with styrene-butadiene latex and oxidized starch are not adopted; and the performances, such as the tensile strength, the surface strength, the softness and the water resistance, of paper can be simultaneously improved just by adopting the surface micro-coating agent to carry out one-step coating.
Description
Technical field
The invention belongs to pulp technology for making paper and chemical technology field, relate to a kind of micro-smears, surface for pure paper and non-woven paper production and preparation method thereof.
Background technology
Pure paper is a kind of novel wallpaper, adopts pure natural wood pulp to manufacture paper with pulp, and carries out trace coating on surface, and its topmost feature is not adopt PVC to carry out later stage coating, is a kind of environment-friendly type, free of contamination pure natural family life decoration paper.
Non-woven paper is in producing the process of hanging raw stock, adds non-woven fibre, and carries out surface trace coating, is a kind of Domestic two life decoration paper.
Traditional paper finishing agent, take carboxylic styrene butadiene latex or oxidized starch conventionally as adhesive and film forming agent, is aided with water repellent agent, and to improve anti-gigging speed and the resistance to water of paper, the softness and the feel that solve paper adopt interpolation softener in slurry.
In tradition coating method and slurry, addition manner can only improve a certain performance of paper, and when solving a certain performance, can be again that another performance of paper is affected often, as: softener can improve feel, but inevitably the WATER RESISTANCE of paper can decline greatly; Film forming agent can improve the surface strength of paper, and the feel of paper can be affected again.
