Therefore, as shown in FIG. 11 , the bending machine P of the present invention includes a work table P1 , a pressure member P2 and a plurality of support members P3 in order to reduce the springback phenomenon.

First, the work table P1 is shown to be formed in a semicircular shape to mount the raw material on the upper side as shown in FIG. 11 , but may be changed to a different shape according to design specifications.

Next, the pressure member P2 is installed to be spaced apart from the upper portion of the work table P1, and performs a pressing operation by applying pressure to the raw material placed on the work table P1 through vertical movement.

In this case, the pressure member P2 may apply pressure to the raw material mounted on the work table P1 using hydraulic pressure.

In a state in which pressure is applied to the raw material through the pressure member P2, the support member P3 supports the outer side of the raw material to fix the raw material.

Here, aminosilanized aluminum hydroxide is not volatilized by heat, and when aminosilanized aluminum hydroxide is included in less than 2 parts by weight, there is a problem that the aqueous solution according to the present invention cannot express flame retardancy and self-cooling properties, and aminosilane When aluminum hydroxide is included in excess of 2 parts by weight, mechanical properties of the aqueous solution may be reduced, and there is a problem in that the manufacturing cost is excessively increased.

In addition, aminosilanized aluminum hydroxide has a property of releasing water when the temperature is 50°C or more and 100°C or less.

Accordingly, the aqueous solution of the present invention preferably contains 2 parts by weight of aminosilanized aluminum hydroxide.

Next, the bisphenol A type epoxy resin is widely used as a coating agent or lining agent because it exhibits abrasion resistance, oil resistance, waterproofness, etc., and the aqueous solution according to the present invention contains 10 parts by weight of a bisphenol A type epoxy resin to improve abrasion resistance.

Therefore, it is preferable that the aqueous solution according to the present invention contains 10 parts by weight of the bisphenol A-type epoxy resin.

In addition, although the aqueous solution in the present invention was shown to contain a bisphenol A epoxy resin, a bisphenol-based epoxy resin such as a bisphenol F-type epoxy resin and a bisphenol AF-type epoxy resin or a novolac epoxy resin may be used.

Next, poly(oxypropylene)diamine is used to cure the aqueous solution at low temperature.

At this time, when the aqueous solution according to the present invention contains less than 3 parts by weight of poly(oxypropylene)diamine, there is a problem that curing of the aqueous solution does not proceed smoothly, and when the aqueous solution exceeds 3 parts by weight of poly(oxypropylene)diamine , it is difficult to control the curing of the aqueous solution, and there is a problem of deterioration of physical properties due to the uncoated curing agent.

Accordingly, the aqueous solution according to the present invention preferably contains 3 parts by weight of poly(oxypropylene)diamine.

That is, the aqueous solution according to the present invention preferably contains 2 parts by weight of aminosilanized aluminum hydroxide, 10 parts by weight of bisphenol A epoxy resin, and 3 parts by weight of poly(oxypropylene)diamine.
