It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the following technical solution is adopted in the present embodiment, and a method for manufacturing a color-changeable sunshade includes the following steps:
s10, providing umbrella cloth, and drawing manuscript patterns on the outer surface of the umbrella cloth.
Particularly, provide the waterproof cloth that the colour is the dark and as umbrella cloth, select dark colour can make reversible temperature sensing when discolouring paint discolour, and more outstanding of pattern colour makes the effect of pattern show better, plays better warning effect. The drawing of the manuscript pattern can be designing and researching a specific drawing pattern, is divided into a unit type small pattern group and a large single pattern, is designed by combining the consideration of a color-changing area, and simultaneously determines the color matching of the base color and the color-changing coating; after design and finalization, a flexible plastic film is used for manufacturing a template, patterns are carved by manual or laser carving methods, the plastic template is used for completely adhering umbrella cloth, and if large-batch manufacturing is required, the patterns can be directly designed by a computer and then screen-printed and sprayed. The template is made of a soft base material and an adhesive, a BOPP adhesive tape can be selected, after patterns are printed by using semitransparent parchment paper, a plurality of layers of BOPP adhesive tapes are compounded on the front surface and the back surface of the pattern paper to form the template with the thickness of 1-2mm, and a pattern filling area is obtained by carving.
In the embodiment, a full and dense water-based acrylic marker pen pigment can be used for drawing, the characteristics of quick drying and good fluidity are utilized for drawing the patterns, the manually drawn patterns are flat, the thickness is 0.1-0.25mm, the effect is similar to that of silk-screen printing, and the next step of operation is carried out after the pigment is dried. The water-based acrylic Mark pen pigment acrylic ink adopting volatile organic solvent and organic micromolecular material is filled into a pen, and patterns are drawn by the Mark pen, so that the effects of quick drying of the base color pattern pigment, good glossiness, bright and beautiful color are achieved.
In this embodiment, the specific shape and content of the manuscript pattern may be set according to actual needs, and are not limited herein.
In this embodiment, after the draft pattern is drawn, the protecting and setting agent may be sprayed once, and after drying, the protecting and setting agent may be sprayed once again, and the spraying may be repeated for 2-3 times to protect the color and shape integrity of the bottom pattern, and then the next step is performed after drying. The adopted protective setting agent has the components similar to oil painting setting liquid, and the components are rosin and organic solvent thereof in the proportion of 1:10 (one part of rosin and ten parts of organic solvent) or a professional inflation tank is adopted for filling the drawing liquid, the components of the drawing liquid are hundred-percent dammar resin, the drawing liquid is quick-drying, the conjunctiva is hard and firm, the drawing liquid has a certain waterproof function, and the completeness of the pattern can be protected.
With reference to fig. 2, in an implementation manner of this embodiment, the step S10 specifically includes: dividing the umbrella cloth into a plurality of areas, and drawing manuscript patterns with different colors and different shapes in different areas; the manuscript patterns in different areas are combined to form a complete picture. If the umbrella cloth is divided into three annular areas, the sizes of the three annular areas can be set according to requirements, and different patterns and reversible thermochromic coatings with different thermochromic critical point temperature values can be set in each annular area. For example, the color changing critical points of the reversible thermochromic paint in the three annular regions gradually rise along the linear direction of the umbrella ribs.
Further, the colors of the reversible thermochromic paint in the two adjacent annular areas can be set to be colors with larger color difference, for example, one is that the temperature change is displayed as red, and the temperature change in the other area is displayed as blue. The color is set to be two colors with obvious difference, so that the prompt effect is more obvious. Especially, when the user is at a high outdoor temperature, the umbrella is unfolded to walk on the road, so that the vision is influenced to a certain extent for better sun shading, the surrounding environment is not easy to observe, and traffic accidents are easy to happen. At the moment, due to the fact that the color of the sunshade changes (the sunshade has an obvious prompting effect), passing vehicles can be well reminded, and accidents are avoided.
In one implementation of this embodiment, after the umbrella cloth is sewn with the umbrella ribs into an umbrella, the region between two adjacent umbrella ribs is used as a dividing region, and different manuscript patterns are drawn in each region, and further, the reversible thermochromic paint with different color change critical points is used for tracing according to the requirement of picture display. It is easily understood that the specific divided areas may be set according to the specific manuscript pattern.
Exemplarily, the designed manuscript picture is a landscape picture, the effect to be displayed is that the spring scenery is displayed when the color is not changed, the autumn scenery is displayed after the color is changed, the same picture is realized, the landscapes in different seasons are displayed, and the ornamental value is improved.
The designed manuscript picture is a pattern formed by small logos of a company, and when the manuscript picture is displayed to the outside, the color of the pattern can be changed when the ambient temperature reaches a certain value, so that the color can be changed when others see the pattern indoors or outdoors, a relatively deep impression is given to people, and the trademark display of the company is facilitated.
After the step S10, the method includes a step S20 of tracing the manuscript pattern with the diluted reversible thermochromic paint to form a reversible thermochromic coating on the manuscript pattern; the manuscript pattern comprises numbers which are the color change critical point temperature values of the reversible temperature-sensitive color-change coating; the reversible thermochromic coating displays a color different from the color of the manuscript pattern.
Specifically, a reversible thermochromic paint which can be changed into a colorless state (which is different in color from the ground color pattern) is prepared, diluted with a diluent 1. Wherein the temperature value of the color changing critical point of the reversible temperature-sensitive color-changing coating is 31 ℃,40 ℃ and the like. It is easy to understand that when the temperature value of the color-changing critical point of the reversible thermochromic paint is 31 ℃, the manuscript pattern can be set to 31, and when several different reversible thermochromic paints are used at the same time, a digital pattern can be set for each reversible thermochromic paint, i.e. different temperature numbers can be displayed.
As shown in fig. 2 and 3, for example, by using the reversible thermochromic paint having a color of red and a temperature value of a color-changing critical point of the reversible thermochromic paint of 40 ℃, the manuscript pattern can be drawn into a flame shape, a numeral 40 is marked beside the flame, and when the outdoor temperature reaches or exceeds 40 ℃, the red flame pattern and the numeral will be displayed to play a significant role in prompting. Can remind surrounding people or users to pay attention to the outdoor time and the heatstroke prevention and cooling.
In this embodiment, the inverse thermochromic paint contains encapsulated reversible thermochromic substances, namely inverse thermochromic pigments (commonly known as temperature-sensitive pigments, temperature-sensitive powders or temperature-sensitive powders), and the finished product can meet the color change times of 4000-8000 times.
In an implementation manner of this embodiment, a reversible thermochromic coating is used to draw a number on the inner surface of the umbrella cover, where the number is a color-changing critical point temperature value of the reversible thermochromic coating. The numbers are arranged on the inner surface of the umbrella cloth, so that a user of the sunshade can be reminded.
And S30, coating an ultraviolet-proof coating on the reversible thermochromic coating to obtain an umbrella cover after the step S20.
Specifically, based on the characteristics of the used paint, a colorless coating of titanium dioxide mixed with zinc oxide organic solvent is sprayed to isolate the damage of ultraviolet rays to the paint and prevent the abrasion of patterns.
And step S40 is included after the step S30, the umbrella cover and the umbrella ribs are sewed, and the color-variable sunshade is obtained.
Specifically, the umbrella cover and the umbrella ribs are placed in a sewing machine for sealing, and the color-changeable sunshade is obtained. The structure of the sewing machine and the sealing process are the prior art and are not limited and described herein.
As shown in fig. 3, based on the same inventive concept, the invention also provides a color-changeable sunshade umbrella, which comprises a support rod 10, umbrella ribs 11 and an umbrella cover 12. The color-changeable sunshade umbrella is prepared by the preparation method. Wherein, the preparation steps involved are not described herein.
