However, the above-mentioned patent documents have a problem that the workability is lowered due to a low thermal deformation against lukewarm due to a problem of adhesion at the time of adhering. Particularly, when the amount of residual In the process of removing the filler, a part of the filler inserted into the flaw is often removed, and the filler must be re-filled to expose the problem of poor workability.

An object of the present invention is to provide a flaw-filling agent capable of improving workability by using a modified wax in which solidification rapidly proceeds in a softened or liquefied state after heat-heating.

It is still another object of the present invention to provide a flaw-filling agent which has a low melting point and is softened by a low temperature to improve workability.

By using the modified wax, adhesiveness and durability according to the improvement of the tackiness and hardness can be improved and the reliability of the product can be secured.

In addition, by modifying the melting point of the modified wax, softening can be achieved even at a low temperature, and workability can be improved.

Since the network is formed by mixing the first and second microcrystalline waxes having relatively small crystals between the large paraffin waxes and the paraffin wax crystals connected by the first and second microcrystalline waxes when the external force is generated , It is possible to remove only the residue of the surface of the substrate while remaining the portion which has been inserted into the scratches at the time of removing the scum on the substrate surface during the filling of the substrate scratches, thereby improving the workability.

In addition, it can be cured quickly after heating at a high temperature or a low temperature, thereby shortening the construction time.

In addition, it is a useful invention that can improve water resistance and water resistance by constituting wax as a base.

Hereinafter, the configuration of the present invention will be described in more detail.

The present invention relates to a paraffin wax comprising 35 to 40% by weight of paraffin wax, 20 to 26% by weight of a first microcrystalline wax, 10 to 16% by weight of a second microcrystalline wax, 4 to 6% by weight of carnauba wax, 1.5 to 2.5% 2.4 to 3.3% by weight of a liquid rosin ester, 12 to 17% by weight of a milling base, and 0.2 to 0.8% by weight of an antioxidant.

That is, the present invention modifies viscosity and hardness by blending a wax which is an organic matter having an alkyl group which is solid or semi-solid at room temperature.

First, the paraffin wax is also called a solid paraffin, which is a mixture of hydrocarbons of a crystalline solid obtained at room temperature, which is obtained from hamburger oil.

It is mainly composed of straight chain paraffin, classified according to the melting point, and used for manufacturing candles, paraffin paper and the like.

These paraffin waxes have a high water-proofing effect and are characterized by their fast penetration strength, strong adhesion, excellent curing after liquefaction and high hardness in a solid state.

The paraffin wax used in the present invention has a melting point of 47 to 64 DEG C, preferably 58.8 DEG C and a density of 0.9 g / cm < 3 >.

The paraffin wax is used as a base member to improve the water resistance and moisture resistance. When the thickness exceeds the critical value, the paraffin wax has a large crystal size. Therefore, the filling operation through the first and second microcrystalline waxes is lowered and the hardness is lowered A problem occurs.

Next, the first and second microcrystalline wax is a solid mixture of hydrocarbons, mainly composed of isoparaffin, and is a hard wax component.

These microcrystalline waxes, also called micro waxes or microcrystalline waxes, are composed of saturated, high molecular weight aliphatic hydrocarbons.

The above-mentioned first and second microcrystalline waxes are made of fine crystals contrary to the large crystals of paraffin wax. The first and second microcrystalline waxes penetrate the pores between the paraffin wax crystals and the crystals to connect the crystals (network and crosslink) And will play an increasing role.

That is, when the first and second microcrystalline waxes are hardened at room temperature, crystals are formed. The first and microcrystalline waxes are more viscous and elastic than the paraffin waxes, and serve as a bridge between the crystals of the paraffin wax .

Particularly, as described above, the paraffin wax according to the present invention has a structure in which a network is formed by the first and second microcrystalline waxes rather than the network formed by the crystal itself. Therefore, by using the present invention, It is possible to prevent the phenomenon that the portion inserted into the scratches comes out from the scratches when the remnants that can not be inserted into the scratches are removed, thereby facilitating the filling work of the scratches.

Here, the first microcrystalline wax has a melting point of 80.9 ° C and the second microcrystalline wax has a melting point of 83.7 ° C.

When microcrystalline wax having a high melting point is used, the effect of increasing the hardness can be obtained. However, the application of the microcrystalline wax having a high melting point has a problem in that the softening of the present invention is performed only when a high temperature is applied to a substrate having scratches, Hardness and workability, microcrystalline wax having different melting points is used. Therefore, the overall melting point of the present invention can be also adjusted downward.

Further, since the first microcrystalline wax has a low melting point, the viscosity of the first microcrystalline wax is also lowered. In this case, the flowability is too high, so that the first microcrystalline wax is inserted into the crystals of the paraffin wax.

Accordingly, in the present invention, by applying two types of microcrystalline wax having different melting points and viscosities, it is possible to increase the hardness through the role of bridging the crystals of the paraffin wax, will be.

When the above-mentioned first and second microcrystalline waxes are mixed below the critical value, the network performance of the paraffin wax crystals deteriorates and the hardness is lowered. When the first and second microcrystalline waxes are exceeded, paraffin wax The network of crystals becomes too hard so that the bonding force between the portion inserted into the scratches on the substrate and the residue on the surface of the substrate is increased so that a portion of the portion inserted into the scratches is removed when the residue is removed, .

Next, the carnauba wax is a wax purified from palm and Brazil wax palm leaves and shoots.

Such a carnauba wax has a very high hardness and excellent glossiness in a natural wax.

In the present invention, carnauba wax is included in order to impart luster while enhancing hardness. When the mixing amount of carnauba wax is less than the critical value, it is difficult to obtain the above-mentioned effect. When the difference exceeds the threshold value, The raised effect is not generated.

Next, the montan wax is a long chain fossil ester obtained from brown coal through solution extraction. It contains free higher alcohol, solid acid, resin, emulsifying compound and the like, and the glass and bound acid account for more than 50%.

The distribution of the carbon number of the acid and the alcohol is different according to the mountain area, and although there are some differences in the properties thereof, it has a hard, sticky, good solvent resistance and excellent glossiness.

In the present invention, the above-mentioned effect is not obtained when the plasticity is imparted by the above-described hardness and the plasticity is improved to improve the slip resistance and glossiness. When the plasticity is lower than the threshold value, The effect can not be obtained.

Next, the liquid rosin ester is obtained by esterifying abietic acid, which is a main component of rosin, which is one of the natural resins, which distills the raw ginseng with water vapor to eliminate turpentine oil. Among them, the glycerol ester of rosin is called ester gum.

The rosin is heated and melted at 190 to 210 ° C, glycerol is slowly added thereto at 10 to 20%, and the jacket temperature is maintained at 250 to 260 ° C for 2 to 4 hours, and finally heated to 300 ° C The reaction time can be shortened by using zinc powder, zinc carbonate or the like as a catalyst and boric acid or acid salts as a dehydrating agent at this time.

The rosin ester thus prepared varies in properties and uses depending on the components. In the present invention, a liquid rosin ester of a methyl bietate is used in order to impart adhesive strength.

When the mixing amount of the above-mentioned liquid rosin ester is less than the critical value, the adhesive force becomes low and the adhesive force can not be added. If the mixing amount exceeds the threshold value, the adhesive force becomes too high, It becomes difficult.

Next, the milling base is included in order to develop hue in the present invention. The milling base is composed of 55 to 65% by weight of titanium oxide, which is in the form of powder of various colors for color development, with respect to 100% And 35 to 45% by weight of a plasticizer for easy handling.

Next, the antioxidant is used as a phenolic stabilizer to prevent discoloration of the color developed in the present invention and to maintain the stability of the product.

The scratch-preventive agent of the present invention composed of the above-mentioned components can improve the convenience of work by improving the hardness and adhesiveness of the wax which is solidified after the heat is applied.

In addition, since the paraffin wax has a structure in which crystals of paraffin wax are bonded by using first and second microcrystalline waxes based on a paraffin wax having a large crystal size, it is possible to use, in addition to the scratch- The paraffin wax is smoothly separated during the removal of the scratch-off filler, so that the scratch-off filler inserted into the scratch-off improves the workability because the scratch-off agent in the scratches is not dropped when the scratch- .

In addition, the flaw-filling agent of the present invention is a modification of the wax, which causes a phenomenon of softening or melting due to heat due to the characteristics of the wax. However, when the fused agent is formed into a low melting point, And after the heat source is removed, a high hardness is formed and the workability can be improved.

Particularly, since the wax is modified, an excellent effect of water resistance and water resistance can be obtained.
