Description
Technical Field
The invention relates to a building decoration material, in particular to brownish black environment-friendly wallpaper.
Background
The wallpaper is a material widely used for indoor decoration, can be made into base paper by pulping wood pulp fibers, and then is obtained by printing and post-treatment, and can also be directly used as the wallpaper by using non-woven fabrics. The wallpaper is popular among people due to the factors of variable style, rich color, convenient construction and the like. With the improvement of living conditions of human beings, the requirements of people on decorative materials used in daily life are higher and higher, and people not only require that the wallpaper has common decorative performance, but also have higher performance on a plurality of additional performances of the wallpaper, such as environmental protection, antibacterial property, flame retardance and the like.
The invention with the Chinese patent application number of CN105544306A discloses an antibacterial mildew-proof wallpaper containing graphene oxide and a preparation method thereof, and particularly discloses that the antibacterial mildew-proof wallpaper is obtained by uniformly distributing the prepared antibacterial mildew-proof agent on base paper through a spraying process. Under the synergistic effect of the nano graphene oxide, the wild lily extract and the nano cerium oxide, the effects of resisting bacteria, preventing mildew and removing peculiar smell are obviously improved. The method mainly comprises the step of attaching the antibacterial agent to the wallpaper through a post-treatment method to enable the wallpaper to have antibacterial and mildewproof effects, but through simple spraying, the acting force between the antibacterial agent and the wallpaper is small, the adhesion time of the antibacterial agent can be shortened, and the antibacterial performance of the wallpaper is further influenced. Meanwhile, the graphene is a substance with color, and the color of the wallpaper is not uniform due to subsequent adhesion, so that the substance easily influences the overall attractiveness of the wallpaper.
As can be seen from the research of preparing the antibacterial wallpaper in the prior art, the wallpaper color is adhered by using an after-finishing process, meanwhile, the processes such as dyeing, printing and the like are complex, and most of the used dyes are synthetic dyes, so that the environment pollution is large.
The invention provides a method for endowing wallpaper with color during wallpaper preparation, aiming at solving the problems of complex process and great pollution existing in wallpaper coloring in the prior art.
Disclosure of Invention
The invention aims to provide brownish-black environment-friendly wallpaper and a preparation method thereof, and particularly solves the problems that the wallpaper in the prior art is single in function, poor in product hand feeling and not easy to remove formaldehyde generated in home decoration, and the specific method is as follows:
the brownish-black environment-friendly wallpaper is characterized in that the wallpaper comprises 0-30 parts of wood pulp fibers, 30-100 parts of polyester fibers, 1-15 parts of glucose, 1-10 parts of starch and water, wherein the water accounts for 20-100 times of the total mass of other raw materials; and carrying out hydrothermal reaction on the glucose and the starch at a high temperature to obtain the nano carbon microspheres.
Preferably, the brownish black environment-friendly wallpaper is characterized in that the wallpaper comprises 5-30 parts of wood pulp fibers, 30-100 parts of polyester fibers, 5-15 parts of glucose, 5-10 parts of starch and water which is 20-100 times of the total mass of other raw materials; glucose and starch are subjected to hydrothermal reaction at high temperature to obtain the nano carbon microspheres.
According to the wallpaper prepared by the invention, glucose and starch are subjected to hydrothermal reaction at a high temperature, and the glucose and the starch are subjected to arylation and carbonization reactions, so that the color of the wallpaper is changed to brown or black.
The dosage of the glucose and the starch also influences the color shade, and the color shade can be controlled by controlling the dosage of the glucose and the starch.
Because the invention experiences high temperature in the preparation process, the dosage of the selected polyester fiber is larger than that of the wood pulp fiber when the wallpaper raw material is proportioned, thus reducing the influence on the mechanical property of the wallpaper caused by high temperature.
The hydrothermal reaction temperature is 130 ℃ and 190 ℃, and the time is 2-5 hours.
The temperature and time of the hydrothermal reaction can influence the aromatization and carbonization degree of the carbon source, when the temperature is too low, the carbon source mainly carries out aromatization, brown wallpaper can be obtained, when the temperature is continuously increased, carbonization mainly reflects, and carbon microspheres are obtained, so that the wallpaper is black. When the reaction temperature is too low and the reaction time is insufficient, the carbon source cannot be aromatized or carbonized, and the color of the wallpaper cannot be changed.
The thickness of the wallpaper is less than 1mm, and the wallpaper is brown or black.
The invention also provides a preparation method of the brownish black environment-friendly wallpaper, which comprises the following steps: (1) preparing a glucose/starch solution; (2) adding wood pulp fibers and polyester fibers into the glucose solution obtained in the step (1), and pulping by using a pulping machine to prepare mixed pulp; (3) making the mixed pulp into raw wallpaper through the procedures of papermaking, squeezing, drying and reeling; (4) and (4) feeding the wallpaper base paper obtained in the step (3) into a high-temperature reaction kettle, adding water, and carrying out hydrothermal reaction to obtain brownish-black environment-friendly wallpaper.
According to the invention, glucose and starch are firstly dispersed before pulping, then pulping is carried out, and sufficient amount of water is added, so that the glucose and starch are uniformly dispersed in the pulp.
And (3) pulping in the step (2) for 0.5-1.5 hours, and controlling the beating degree of the pulp at 50-60 DEG SR.
As the performance of the sizing agent can influence the performance of the final wallpaper, according to multiple tests, the beating time is 0.5-1.5 hours, the beating degree of the sizing agent is controlled under the SR condition of 50-60 degrees, and the prepared wallpaper is good in hand feeling, good in flexibility and high in quality.
And (3) one or more of a flame retardant, a softening agent and a water repellent agent can be added into the slurry during pulping in the step (2).
According to the requirements of the performance of the wallpaper, corresponding functional finishing agents can be added in the preparation step of the sizing agent, and the functional finishing agents are better fixed with the wallpaper due to the addition of the functional finishing agents in the pulping process.
The reaction temperature of the step (4) is 170-190 ℃, and the reaction time is 2-5 hours.
The invention aims to provide brown-black environment-friendly wallpaper, which is prepared by adding glucose and starch into raw materials, aromatizing and carbonizing the glucose and the starch through high-temperature heating, and further endowing the wallpaper with brown-black color, and brown wallpaper with uniform color can be obtained by controlling the dosage ratio of the glucose and the starch and the temperature and time of hydrothermal reaction.
