Coating a reinforcing resin composite comprising a weight part, and after the coating of the reinforcing resin composite is bonded to the reinforcing woven or non-woven mat to dry before the coating layer is configured by re-coating the reinforcing resin composite on the surface of the mat do.

In addition, of course, a plurality of the reinforcing mat and the resin composite layer as described above can be laminated alternately. In this case, the longitudinal direction of the fibers of the reinforcing mat to be laminated a plurality is different from each other, or it is preferable to secure a strength to achieve a constant angle.

In addition, a reinforcing resin composite including 10 to 400 parts by weight of glass powder and 1 to 400 parts by weight of glass fiber is applied to 100 parts by weight of the room temperature-curable organic liquid resin without using such a lamination method. The interior may also be reinforced by combining reinforcing woven or nonwoven mats. That is, the reinforcing woven or non-woven fabric mat is immersed in the reinforcing resin composite, or the resin composite is coated on both sides of the mat by a known method such as roller, spray, or brushing, and then directly applied to the inner surface of the vehicle panel. A method of gluing and hardening may be applied. In this case, the coated reinforcing mat as described above may be stacked in alternating manner, and in this case, the longitudinal direction of the fibers of the plurality of laminated reinforcing mats may be alternating with each other, or at a constant angle. It is desirable to ensure the strength to achieve.

The vehicle bulletproof panel may include various known bulletproof panels used in automobiles, and specific examples thereof include door panels, roof panels, side panels, A pillar panels, B pillar panels, C pillar panels, hood panels, and the like. Can be mentioned.

This may be mainly made of metal such as a high tensile steel sheet or an aluminum alloy plate, or a resin panel or a laminated panel thereof. The door panel, a roof panel, and a hood panel made of a high tensile steel sheet or an aluminum alloy plate may correspond to this. It is good to apply to this.

The room temperature-curable organic liquid resin used in the present invention may be used as it is, epoxy, acrylic, urethane, alkyd, polyester, or polyvinyl chloride. The epoxy-based resin is preferably a solvent-free or solvent-diluting epoxy resin having a molecular weight in the range of 350 to 3,000 MW among diglycidyl and triglycidyl types. The acrylic resin is preferably an acrylic urethane, an aqueous acrylic hydrosol, an emulsion-free acrylic silane, an ultraviolet curable acrylic, or the like having a methacrylic acid derivative as a main component. The alkyd based resin is preferably an alkyd resin in a paint form modified with a polybasic acid and a polyhydric alcohol ester compound, and includes rosin, phenol, epoxy, and vinyl styrene monomer. ), Alkyd resins modified with isocyanate, silicon, or the like can also be used. The polyvinyl chloride system preferably uses a plastic sol liquid resin of PVC.

These resins act as a binder of the resin composite, impart acid and alkali resistance, add a curing agent if necessary to cure, and a curing accelerator may be used to control the curing rate. Of course, the selection of these curing agents and curing accelerators can be determined according to the type and amount of the resin.

Such a room temperature-curable organic liquid resin has a problem that the binder capacity is weak when the content is too low, the content of the glass powder is reduced when the content is too high, the strength and physical properties are generally poor.

The glass powder used in the present invention may be mixed with the resin to increase the viscosity, and after curing, the impact resistance may be increased by filling the pores of the resin. In addition, the glass powder hardens the surface hardness after the resin is cured with a rigid material having a hardness of 6 to 7 significantly reduces the generation of scratches caused by external pressure, thereby improving the scratch resistance, When contaminated, contaminants can be easily removed and removed by water, thereby improving pollution resistance and improving corrosion resistance.

The glass powder may be one of various particle shapes and particle sizes, and the particles of the glass powder are obtained by pulverizing general glass, and the glass composition is compatible with resins such as A, C, E, and alkali-resistant glass powder compositions.

If the content is more than 400 parts by weight, the viscosity may be increased too much, and the resin content may be lowered to lower the strength. There is a problem that the composite may be dropped after curing.

In addition, the resin composite applied to the present invention containing the above components includes glass fibers. The glass fiber is present in the resin to increase the tensile force of the resin composite to be cured, and serves to prevent cracking of the resin composite due to bullets or fragments.
