Double-base propellants with improved mechanical properties and combustibility

Double-base propellants with improved mechanical properties and combustibility. (Nippon Oils and Fats Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58194791 A2 12 Nov 1983 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C06D005-00. APPLICATION: JP 82-75372 7 May 1982. DOCUMENT TYPE: Patent CA Section: 50 (Propellants and Explosives) Double-base propellants having improved mech. properties and combustibility contain aliph. diester compds. 2-15 and multifunctional isocyanate compds. (mol. wt. ￡500) 0.1-5%. Thus, a slurry contg. nitroglycerin [55-63-0] 4500, di-Bu adipate [105-99-7] 1000, 2-nitrodiphenylamine [119-75-5] 200, Pb salicylate [15748-73-9] 200, Cu salicylate [20936-31-6] 100, isophorone diisocyanate [4098-71-9] 50, dibutyltin dilaurate [77-58-7] 1, and nitrocellulose [9004-70-0] 4500 g was molded and hardened at 50° for 10 days to give a propellant having high tensile strength (14.2 kg/cm2) and good combustibility.Except for chemicals metioned above, 119-75-5 and 15748-73-9 are also used. .

Thermosetting coating materials

Thermosetting coating materials. (Kanegafuchi Chemical Industry Co., Ltd., Japan).In this study， 89118-83-2 and 89118-80-9 are also used. Jpn. Kokai Tokkyo Koho JP 58157810 A2 20 Sep 1983 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F220-18; C08F212-08; C08F230-08. ICA: C09D003-81. APPLICATION: JP 82-39223 11 Mar 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Weathering-resistant thermosetting coating materials are prepd. by polymg. arom. vinyl compds. 0-50, polar vinyl compds. 0-20, silanes having alkenyl groups and hydrolyzable groups 5-35, and alkyl (meth)acrylate 20-95 parts. Thus, a mixt. of styrene 30, 3-methacryloyloxypropyltrimethoxysilane 30, Me methacrylate 30, Bu acrylate 10, xylene 100, and AIBN 4 parts was heated 10 h at 130° to give a soln. of copolymer [84154-41-6] having no.-av. mol. wt. 6000. The above soln. contg. 2% (based on polymer) Bu2Sn dilaurate [77-58-7] was thinned with xylene, applied to a polished steel plate, dried 30 min at 60°, and left 7 days at room temp. to form a coating having pencil hardness 2 H, discoloration after 24 h of UV irradn. (DE) 3.0, and good resistance to gasoline and water. .
