の粘度か低いために、この傾向が特に著しい。Airfield runways are generally paved by laying several kilometers of concrete plates and applying sealant at the joints.
It is replaced every 0 years. In the case of this replacement or repair work, the time available for construction is limited due to the convenience of aircraft take-off and landing, and the work must be carried out even in some bad weather. However, when the two-component urethane sealant used for this comes into contact with moisture or rainwater in an unused state, it hardens and foams, deteriorating its physical properties and resulting in an extremely poor surface finish. If it rains during or immediately after construction, re-construction is required, which is not only extremely uneconomical, but also poses the problem that construction cannot even be carried out during the rainy season. Therefore, conventionally, a protective measure has been proposed in which the sealant surface is coated with a solvent-based Bly-2- and the solvent is blown away to form a waterproof film, but this method does not allow the sealant to become exposed to mII or be brushed off. The surface of the sealant may be deformed, making it impossible to obtain titration results. Furthermore, this tendency is particularly noticeable in self-leveling type sealants used for horizontal joints such as runways, because the viscosity of the sealant is low.

に至った。As a protective measure, the present inventors investigated a method for forming a waterproof film that does not adversely affect the sealant, and found that by spraying an oil or wax that is solid at room temperature in a hot molten state, the desired result can be instantly achieved. The present inventors have discovered that a waterproof film is formed and that it is also useful for preventing stains, leading to the completion of the present invention.

ってもよい。In the present invention, the oil and fat that is solid at room temperature (melting point/freezing point is 20'
For example, drying oils such as aca litum oil, sinagiri koku, rubber seed oil, semi-drying oils such as rice bran oil, and non-drying oils such as kapok oil, etc. Oil, iribe fat, ukufupa fat, sumac wax, cacao butter, garcinia fat, kusum fat, laurel butter, gorli fat, shea butter, big fuko oil, tsukan oil, tsukan ridge oil, deica butter, trumpet butter, nikuduku butter, chive butter fat, bakery oil, palm oil, balm extract oil, hydnocarbus tune,
Vegetable fats such as Brazilian balm kernel oil, porneo fat, Malabar fat, Murumuru fat, Japanese wax, and coconut oil, beef tallow, beef kidney fat, beef bone oil, beef fat, human milk fat, pig intestine, horse tallow, mutton fat, sheep fat Examples include animal fats such as dairy fat, duck fat, goose fat, sparrow fat, kite fat, and starch fat. In addition, examples of waxes that are solid at room temperature and can be used in place of or in combination with such oils and fats include carnauba wax, spermaceti wax, sugarcane wax,
Examples include shellac wax, wax wax, palm wax, beeswax, montan wax, and wool fat, and paraffin and the like can also be used. These oils and waxes can be used alone or in a mixture of two or more, but
Among them, it is particularly preferable to use acaritum fat, rough camellia fat, Japanese wax, beef tallow, pig intestine, and spermatozoa, which have good workability because their melting points/freezing points are around 30 to 50°C.1°・Curing method according to the present invention Usually, the above-mentioned oil and/or wax is heated to a molten state at about 70 to 80°C along the surface of the two-component urethane sealant applied for pouring.
Apply in an amount of 00 to 500'i/d. Application can be done by hand spray, and unlike brush application, it can be applied easily and in a short time, and there is no surface deformation of the sealant due to brushing. By spray coating in this manner, the oil/wax which is in a molten state after coating is cooled, and the desired waterproof/stainproof film is formed instantaneously, for example, after 1 to 2 seconds. The sealing material can be cured in the formed film as it is, and if necessary, the film may be wiped off or left as it is and removed naturally.

なく、また表面外観上も良好であった。Examples include two-component urethane sealing material [manufactured by Sunstar Giken Co., Ltd., Penguin Rule s7oM, III: 100 parts of urethane polymer (incyanate group content 2.3% by weight), curing agent: 40 parts of polyalkylene ether triol, filling 1,140 parts of plasticizer and 20 parts of plasticizer] was poured into a long joint with a width of 16+a and a depth of 16rrrIn, and then commercially available lard (
Pig intestine (melting point/freezing point 28-48°C) is placed in a hand spray container (1000cc), melted with boiling water of about 80°C, and applied to the surface of the IJing material at about 150 P/d.
Spray it so that it looks like this. The sealant was cured by sprinkling water on the cooled and solidified lard film (sprinkling water with a watering pot), but the cured sealant had no foaming and had a good surface appearance.
