Generally, when a fabric for a curtain or a blind is used in a dark room, a shape such as a surface pattern of a fabric is expressed for the interior decoration effect, and the light entering from the outside should be completely blocked.
Thus, conventionally, the fabric is thickly woven tightly together with the fabric, and the external light is blocked by using the opacity of the yarn used in the fabric.
However, curtains and blind fabrics manufactured by the above method have a disadvantage that they are heavy in weight and have a complicated weaving method, resulting in a high manufacturing cost.
In order to solve this problem, a method has been disclosed in which a dark coat is coated on a fabric for a curtain or a blind to provide a dark coat.
On the other hand, when the conventional textile fabric is applied to a blind or a curtain, it is necessary to shut off and reflect solar energy flowing through a window. Most of the textile fabrics are disclosed only for the film, so that the transmission of sunlight can be blocked. There is a structural problem that most of the solar energy is transferred to the room and the room temperature is increased because there is no function.
In order to solve these problems, recently, a method of coating a thermal barrier material such as ATO on a fabric has been attempted. However, since the ATO particles are not easily dispersed in the knife coating process and can not overcome the technical difficulty of precipitation, This is not the case.
In addition, when ATO particles are coated on fabrics, it is not possible to use them as blind fabrics if the color of ATO of dark blue color is exposed on the surface during final coating, but it is difficult to manufacture a coating composition for controlling it effectively .
Therefore, it is necessary to develop a fabric that can block sunlight and heat together.

A dark coat layer (2) on which a light - shielding coat composition is formed on the surface of the fabric fabric;

Any opaque film coating composition may be used as long as it can form a dark coat.
As a preferred undercoat coating composition according to the present invention, a polyurethane coating composition and a polyvinyl chloride coating composition are applied by knife printing or screen printing, followed by drying to form a polyvinyl chloride coating layer and a polyvinyl chloride coating layer, . The polyvinyl chloride coating layer coated with or coated with the polyvinyl chloride coating composition and the polyurethane coating layer coated or coated with the polyurethane coating composition on the surface of the polyvinyl chloride coating layer may each be composed of a plurality of layers in accordance with the required application.
The polyvinyl chloride coating composition used for the polyvinyl chloride coating layer is prepared by blending 25 to 35 parts by weight of pigment and 10 to 20 parts by weight of a flame retardant with 100 parts by weight of polyvinyl chloride (PVC) Based on the weight of polyvinyl chloride, 60 to 70 parts by weight of a plasticizer, 2 to 3 parts by weight of a heat stabilizer, and 2 to 3 parts by weight of a dispersing agent are mixed with polyvinyl chloride.
The reasons for limiting the pigment and the flame retardant as described above are that the hue of the pigment is smoothly mixed with the polyvinyl chloride coating composition so that the color is expressed while the viscosity of the polyvinyl chloride is maintained at the optimum state so as to be adhered to the fabric . If it deviates from such a limited value range, it is not manifested in the appearance of the embryo, and the viscosity is weak or too thin, and the adhesiveness becomes poor.
The reason for limiting the composition range of the plasticizers, heat stabilizers and dispersants as described above is to prevent softening and elasticity of the polyvinyl chloride coating composition so that the polyvinyl chloride coating composition is not released even in small movements of the fabric.
The pigment is preferably white in order to make the color of the textile fabric remarkable, but it may be selected in consideration of the color of the fabric in different colors. In addition, antimony flame retardants (Sb 2 O 5 or Sb 2 O 5 ), bromine flame retardants and the like are used as flame retardants, but since the fabric of the present invention is mainly used for indoor use, it is preferable to use a flame retardant of non-toxic nature.
The polyurethane coating composition is prepared by mixing 55 to 65 parts by weight of toluene and 12 to 20 parts by weight of aluminum powder with polyurethane based on 100 parts by weight of polyurethane.
The reason for limiting the formation of toluene as described above is to have an optimum state of adhesion while increasing the softness of the polyurethane due to the introduction of the solvent. Therefore, if the amount is less than the above-mentioned range, the fluidity is lowered and the viscosity is lowered to lower the adhesiveness. If the amount is larger than the above-mentioned value, the fluidity becomes too large and the viscosity becomes too thin.
The reason why the aluminum powder is limited as described above is that the function and color of the aluminum powder are deteriorated when the amount is less than the above-mentioned numerical range, and if it is larger than the numerical value range, the adhesion performance with polyurethane is deteriorated.
Hereinafter, ATO (antimony trioxide) particles having a heat shielding function applied to the surface of the dark coat layer constituting the
The final thermal barrier coating composition according to the present invention comprises 16 to 20 wt% of PU, 8 to 10 wt% of ATO solid, 8 to 10 wt% of AL paste, 16 to 19 wt% of MEK, 21 to 27 wt% of Toluene, 17 to 24 wt% 0.5 to 1 wt% of an inhibitor, and 0.5 to 1 wt% of a dispersing agent.
The final thermal barrier coating composition prepared as described above is prepared by blending a primary composition containing PU (polyurethane), a secondary composition containing ATO (antimony trioxide) and AL (aluminum paste) PU, ATO and AL pastes contained in the secondary composition are mixed together in a weight ratio (wt%) of 2: 1: 1.
The reason why the mixing ratio of the primary composition and the secondary composition is limited is as follows. When the composition weight ratio of the PU to ATO + AL paste is not 1: 1, the adhesiveness is lowered, When the product is made, ATO and AL paste are separated from the coating surface, so the mixing ratio should be satisfied.
When the coating composition is kneaded in a kneaded state with a viscosity of 10,000 to 20,000 cps and a coating layer at a coating temperature of 150 to 170 ° C in a horizontal state, As a result, a high-gloss silver colored AL paste is positioned on the surface layer by ripping, and a layer separation occurs in which the ATO is located on the backside layer.
The reason for limiting the viscosity is that if the viscosity is too low beyond the above-described range, the coating layer is not formed with a uniform thickness because of high fluidity, and ripping phenomenon is difficult to occur, so that the AL paste is difficult to locate on the surface layer, There is a disadvantage that rippling phenomenon of the AL paste is difficult to occur due to too much fluidity, difficulty in forming a coating layer, surface roughness, and high viscosity.
The primary composition is composed of 15 to 18 wt% of ATO solid, 15 to 18 wt% of ALPaste, 28 to 34 wt% of MEK, 28 to 34 wt% of Toluene, 1 to 2 wt% of precipitation inhibitor and 1 to 2 wt% of dispersing agent.
The main reason for the primary composition of such a primary composition is to increase the ripening power of the AL paste by increasing the dispersibility of ATO and kneading the knitted fabric to the textile fabric, Toluene is used and dispersants and anti-settling agents are used.
In addition, in order to prevent the dark blue color of ATO from being expressed, a high-gloss AL paste is added, and the AL paste is floated upward by the horizontal coating or ripping phenomenon, so that ATO is positioned on the fabric side by layer separation, (AL) paste of silver color is solved to solve the color related problem of ATO. Moreover, since AL paste has heat reflection function, ATO is thermally reflected and only the remaining solar heat is blocked, thereby further enhancing the heat shield effect.
The ATO is used for heat shielding. If less than 15 wt% is added, ATO performance is lowered. If more than 18 wt% is added, coating workability is lowered and dispersion, sedimentation and color problems are caused.
The high-gloss AL is used for heat reflection. When less than 15 wt% is added, there is a disadvantage that ATO color cover is impossible. If more than 18 wt% is added, there is a disadvantage that glaze of the fabric is generated and adhesiveness is lowered .
The high-gloss AL used in the present invention is advantageous in that the non-leafing type AL paste used in the conventional blind coating and the like is inexpensive. However, since the AL paste penetrates into the inside when forming the tabular film, Because of the difficulty in developing the performance, another high-gloss AL paste (particle) was used. As described above, the high-gloss AL paste of the Leafing type used in the present invention has the effect of aligning the pigment on the surface layer in a flat form in the binder during the formation of the film. Therefore, when the high-gloss AL paste and ATO are blended, the AL having heat-reflecting ability is arranged on the surface layer, and the ATO material having the thermal barrier property is arranged downward to have both heat reflection and heat- The color can be covered with silver color of AL paste.
As mentioned above, the ATO and the high-gloss AL are added in an amount of 30 to 34 wt%, and the ratio of ATO and AL can be appropriately adjusted. However, ATO should not be added more than AL because its dispersibility / adhesiveness / color development is poor. Also, when the ratio of ATO is decreased, it is difficult to manifest the performance of the thermal barrier, and it should be applied within the above-mentioned range in compliance with the numerical limitation conditions.
Methyl ethyl ketone (MEK) is a solvent used for the dispersion of ATO, and it is adjusted within the range of 28 to 34 wt% depending on the addition ratio of ATO. If the added amount is less than the above range, ATO is not dispersed well, and if it is added too much, the composition becomes too thin and adhesiveness is deteriorated.
The above toluene is used as a solvent (solvent), and is used for high-gloss AL dispersion, and it is adjusted within the range of 28 to 34 wt% according to the addition ratio of AL. If the addition amount is less than the numerical value range, the dispersion of AL does not occur well, and if too much is added, the composition becomes too thin and adhesiveness becomes poor.
The dispersant uses an oil-based dispersant to smoothly disperse the entire first-order composition. If less than 1 wt% is added, there is a disadvantage that dispersion does not occur well. If more than 2 wt% is added, there is a disadvantage that adhesiveness is lowered and physical properties of the material are changed. In this case, the use of the hydrotreated Haevy naphtha type (heavy hydrogenated naphtha type) is preferable among the oil dispersing agents. Also, since dispersants are expensive, it is recommended to use only the minimum amount. Since the oil-based dispersant is in a liquid state, it may be added at the time of dispersion by a high-speed mixer.
The anti-settling agent is used for preventing quenching and aggregation of the entire first composition, and an oil-based anti-settling agent is used. If the anti-settling agent is not added, the ATO and the AL paste will sink to the bottom and coagulate. Therefore, anti-settling agent is added to prevent reattachment and to prevent aggregation.
If less than 1 wt%, the sedimentation and aggregation prevention effects do not occur. If more than 2 wt% is added, there is no increase in sedimentation and aggregation prevention effect and only the same effect is shown. . The anti-settling agent is preferably a polyamine amide salt type because it is preferable for the quality of the composition.
The second composition is composed of 35 to 45 wt% of solid PU, 12 to 18 wt% of toluene, and 37 to 53 wt% of N, N-dimethylformamide (DMF). The secondary composition serves as an adhesive for the primary composition when knife coating is applied. In addition, it is also possible to prevent pinhole phenomenon or roughening of the coating surface when the thermal barrier coating composition is processed at a temperature of 150 ° C to 170 ° C . For this purpose, DMF and Toluene, which are solvents with different boiling points, were used as PUs, which act as main adhesives.
The PU is used for enhancing the adhesion performance. When less than 35 wt% is added, the adhesion is deteriorated. When the PU is added more than 45 wt%, the coating layer is too thick to be used as a fabric such as a blind or a curtain. It gets worse and causes stability problem.
Toluene and DMF are used as solvents when preparing PU mixtures for coating ATO and high-gloss AL paste because Toluene and DMF have different boiling points. That is, when only PU and one solvent are mixed, the thermal sublimation may occur at once and pinholes (fine holes in the coating film) may be formed or the surface may be roughened due to the boiling phenomenon. In the present invention, by using DMF and Toluene having different boiling points, The same problem was solved. For reference, the boiling point of toluene is 110.8 ° C, the boiling point of MEK is 79.6 ° C, and the boiling point of DMF is 153 ° C.
Also, the viscosity of the PU mixture (secondary composition) is 90,000 (10000 to 20000) cps. If the viscosity is too high, there is a disadvantage in that the uniformity or coating is poor. If the viscosity is low, the adhesion is excellent. However, if the viscosity is too low, the formability is too low.
If the viscosity of the PU is mixed according to the blending ratio of the first composition and the second blend, the viscosity of the entire thermal barrier coating composition is controlled to 10,000 to 20,000 cps. In such a section, excellent workability is obtained.
If the addition amount of DMF is larger than the above-mentioned value, the boiling point is too high to be processed, and if the addition amount of Toluene is larger than the above-mentioned value, the boiling point is too low to maintain the quality of the coating layer. Therefore, it should be prepared in accordance with the numerical condition proportions of the two solvents defined above.
As described above, since the heat shielding coating composition composed of the primary coating composition and the secondary coating composition maintains the viscosity at 10,000 to 20,000 cps and knife coating is performed, the blind fabric fabric is usually made up to 290 cm to 300 cm, A train fault layer can be obtained.
