The present invention is widely used in furniture, construction and industrial, and relates to a multi-purpose composite sheet and a continuous manufacturing method using a combination of cotton fiber, inorganic and synthetic resin solution. More specifically, in order to produce various types of composite plates having different thicknesses, pulp fibers wound in a roll form as a planar fiber in a solution mixed with inorganic fine ocher and melamine resin of synthetic resin together. The rolled product, which has been rolled and released, is overlapped with the supporting cloth and impregnated in the above mixed solution, and then passed through the interlocking rotating roller structures to remove excess impregnation solution and the surface is adjusted. The present invention relates to a multi-use composite plate and a continuous manufacturing method that is subjected to a high temperature drying and curing process of the secondary condition to make an insoluble plate.

In order to achieve the above object, the present invention selects and impregnates pulp as a main material, and impregnates the solution using a mixture of an impregnated melamine resin and an appropriate amount of fine ocher, which are widely used in the melamine decorative plate manufacturing process. In order to prevent the sagging or loosening in the process of the process, to support the non-woven fabric of chemical fibers or inexpensive fibrous fabrics, and also to impregnate the bottom of a number of plane pulp that is released, In order to adjust the surface of impregnated surface and to remove excess impregnation liquid, it was allowed to pass through the rotating roller structure in a drying chamber of 80 ° C or more and 120 ° C or less and in the continuous process followed by 100 ° C or more and 120 ° C. It passes through the drying chamber under the following secondary conditions and performs high temperature drying and curing Through the surface adjustment process of passing through the rotating roller repeatedly, the harmful volatiles are removed and the hardening action is completed, and the insoluble and versatile composite plate is made, including the above steps. It is characterized by the loss.

In general, the contents of the production of mellite plate material using the bakelite plate material and melamine resin liquid using the phenol resin solution, for example, the paper or cotton fibers, synthetic fibers, etc. used for impregnation are expensive to buy.

This is because pulp or yarn is purchased and distributed as a one-step processed product. In addition, the production method is also a way to improve the way to produce a small amount by using a thermo-hydraulic press machine by cutting the primary dry matter, stacking several sheets in order to make different types of plate. And in order to become a patterned paper plate, separately prepared patterned building materials are put on the surface, and they are formed by hot pressing. As another example, in the case of reinforcing plastic sheet production using unsaturated polyester resin liquid and fibrous fabric of processed goods, the concentration of the resin liquid is too high, so that it is difficult to adjust and use, and it needs to be cured quickly in just a few minutes. Because of this, it cannot be a continuous mass production.

After all, material cost and processing cost are high, and it is small quantity production by press.

These include the bakelite plate used as an electric insulation board, a heat insulation board, and a melamine decorative board that is frequently used as a partition surface plate for furniture and industrial use.

In order to improve the deficiency of the prior art as described above, the present invention uses a pulp of low fiber cost as the main material to reduce the material cost and to use the pulp wound in the form of several rolls. It has the property to make products of different thicknesses easily commercialized, and even if the fiber cotton cloth that makes the impregnation process smoothly acts for the thickness of the product, it does not affect the price of the finished plate. In addition, unlike the prior art, high-temperature drying and hardening of secondary conditions are performed, and the surface adjustment process is performed to allow mass production of multi-use composite boards that have been cured continuously. The only drawback is the surface gloss of the finished board. It is lower than that of the prior art products, which can never be said to be a disadvantage, and shows its characteristics according to the present invention.

In order to achieve the above object, the present invention uses a pulp wound on a roll of planar fiber as a center material in a mixed solution of an inorganic fine ocher and a melamine resin of a synthetic resin system to make a multipurpose composite plate material. In order to prevent loosening or elongation during the impregnation process, impregnate the fabric with non-woven fabrics or other inexpensive fibrous cotton cloth, and then impregnate it with the pulp to remove the excess impregnation solution and go through the primary drying process. High temperature drying and hardening of the secondary condition, and the surface adjustment process of the roller structure that passes through the rotating rollers to be intermittently removed to remove harmful volatiles and the hardening operation is completed. Being a multipurpose composite sheet that includes a large amount of continuous production through To is characterized. Additional items include organic pigments, inorganic powders, dye solutions, paint powders, gold powders, gold powders, pearl powders, pearl powders, and the like. In addition to the pattern paper, pattern cotton cloth, and the printed pattern for the metal plate, such as copper plate, aluminum plate, stainless steel plate, titanium plate, etc. can be used as an adhesive for surface rendering.

Hereinafter, described in detail by the accompanying drawings as follows.

Figure 1 is a representative view and the pulp of the cotton fiber wound on the roll (1-1 to 1-3) is released and in the process of impregnation to prevent the loosening or stretching in the impregnation solution, several rolls while acting as a support cloth Nonwoven fabric impregnated with overlapping pulp or cotton fiber cloth of low price (2), wound and impregnated with fine ocher and melamine resin solution (3). The excess mixed solution is removed by the rotating roller 8, which is configured to pass through the dryer 5 of the primary structure, and then passes through the dryer 6 of the secondary conditions in a continuous process. The high speed drying and hardening action to remove surface volatiles and harmful volatiles are completed by the rotating roller structured with It is a manufacturing process diagram of the multipurpose composite board material 7 which enables it. As an additional addition to the manufacturing method described above, a pattern paper, a patterned cotton cloth, and a printed material that can be used as a composite plate of another personality by bonding on the surface of the present invention and a kind of material for color and pattern expression that are commonly used. The following table shows the details that can be joined together with plates such as aluminum, copper, and stainless steel.

As described above, the present invention uses the pulp of the cotton fiber as a main material to obtain a material cost reduction effect that is different from the prior art, and joins the supporting material on the bottom to make the impregnation work smooth. By developing and utilizing the secondary process where the high temperature drying and hardening effect is carried out following the primary process of drying, the continuous mass production can be avoided by avoiding the small production, which is expensive in the prior art. It can reduce the manufacturing cost.
