性質のものとなる。Acrylic or acrylic styrene latex is used as the resin latex. By using these latexes, it is possible to emulsify the rubber asphalt emulsion at a relatively low temperature, and emulsification aids (Na2P203,
When using an electrolyte (such as Na z Si O4), coagulation is difficult to occur and it is easy to disperse and emulsify. Furthermore, the waterproof coating formed using the obtained rubber asphalt emulsion has excellent properties such as hardness, strength, and flexibility, which are highly flexible depending on the application.

被着体が色色変化した場合も接着性が良い。In particular, when using a cement-based hardener, SBR-based alone has disadvantages as a waterproofing material, such as high shrinkage, low elongation, and poor adhesion, but this can be easily achieved by using acrylic latex. It is possible to obtain a rubber asphalt emulsion that has properties that are compatible with cement and has excellent flexibility and elongation. It also has good adhesion even when the adherend changes color.

たりして乳化が難しい。The rubber asphalt emulsion of the present invention consists of 10 to 90 parts by weight of acrylic or acrylic styrene latex and 90 to 10 parts by weight of SBR latex (ie, a total of 100 parts by weight of latex), and an emulsifier as needed. Add and stir at 90-140℃ for 200-900℃.
It is obtained by co-emulsifying by gradually adding parts by weight of molten asphalt. If it is less than 60°C, the viscosity is high and it is difficult to work. On the other hand, if it exceeds 170°C, the emulsification system will boil and emulsification is difficult.

。If the amount of acrylic or acrylic styrene latex is less than 10 parts by weight, it is difficult to exhibit its effect (90 parts of rubber, 1 part of acrylic).
0. When asphalt is 300, acrylic is less than 10/400 and less than 2 inches). On the other hand, 90 weight 1
If the amount exceeds 10 parts by weight, the SBR will be less than 10 parts by weight, making it difficult to obtain a rubber-asphalt emulsion with good elasticity and adhesive properties.
ＳＢＲが１０重量部未満ではＳＢＲの効果が出ない。If SBR is less than 10 parts by weight, the effect of SBR will not be exhibited.
他方、９０重１部を越えるとアクリルの比が少くアクリ

If the weight part is exceeded, the effectiveness of the repolymer will decrease if the rubber or resin content is less than 10 parts per 100 parts.

好ましいがセメント系硬化剤の使用がむづかしくなる。The solids content of the rubber asphalt emulsion of the present invention is preferably from 60 to 80 inches. If it is less than 6 degrees, the amount of cement hardener increases and the elongation becomes a little brittle. Also, it dries slowly when applied. If the diameter exceeds 8 o'clock, it is preferable for coating, but it becomes difficult to use cement-based hardeners.

、乾燥による肉やせも少く硬く延びのあるものとなる。When using the rubber asphalt emulsion according to the present invention, if the temperature is sufficient for drying, it can be applied directly without using a curing agent, and the effect as a coating film waterproofing material can be fully exhibited. Furthermore, if a cement-based coagulant is used as a hardening agent for coating, water will be included in the cement and an excellent film can be formed. In this case, the strength and adhesion of the coating film are particularly improved, its ability to prevent swelling due to water vapor generation from the base, etc. is reduced, and it becomes hard and stretchable with less thinning due to solidification and drying.

補修等に有効な塗膜防水材とすることが出来る。The amount of cement-based coagulant used varies depending on the water content of the rubber asphalt emulsion (i.e., the solid content), but the amount of cement to be used is 140 to 140 parts per 100 parts of water in the emulsion.
It is 200. The hardness of the eardrum that is formed depends on the amount of cement, but a hard one can be applied directly to the concrete slab surface to create an extremely resistant material, or it can be applied to the top surface of the Mononoke waterproofing layer, which has a large elongation, to prevent it from elongating. It can be used as a paint film waterproofing material that is effective for repairing thick paint films and cracks.

可能であり作業時間も大巾に短縮することが出来る。In these cases, the curing agent is cement-based, so it can adhere even if the substrate is damp, and if a curing accelerator is used, the curing speed will be faster, reducing the time it takes to apply the next layer. It is possible and the working time can be greatly reduced.
