Aliphatic glycol dibenzoate (DEDB) Formula: C18H18O5 formula:-COOCH2-CH2-O-CH2-CH2OOC-known: 8611 new plasticizer diethylene glycol dibenzoate ester (referred DEDB), molecular weight: 314, is a colorless, odorless, non-toxic environmentally friendly new superior plasticizer. English name: Diethylene glycol di-benzoate Name: Benzoflex2-45 First, the product uses: 1, the product is widely used in polyvinyl chloride and its copolymers, high filler flooring, PVC wallpaper, ethylene vinyl acetate copolymer, polyvinyl acetate, cellulose acetate butyrate and cellulose nitrate or plastic and chloroprene rubber, styrene butadiene rubber, butyl rubber and polychloroprene rubber, grease, hot melt adhesives; for the manufacture of phenolic resin friction materials , can improve the performance of thermal expansion and thermal fading friction material; which is characterized by a lower melting temperature, the solvent rapidly resin, the article high tensile strength, excellent antifouling properties, solvent resistance and good oil extraction, a very prominent stability and lower play, light color is good, can improve product flexibility, thermal denaturation and flexibility twisting and products adhesion, mechanical stability; product transparency, smooth surface and bright, good gloss . 2, the product with the DOP, DBP match with better results. Mechanical properties superior to DOP, DBP and can inhibit the effects of oil exudation. Can shorten the kneading (variable mixing) time, improving the processing flow. In an alternative formulation moderate, without changing the processing conditions. Second, technical indicators and related data: 1, was determined with the Shin fat (DOP) compared as follows: begin to dissolve the whole solution cloud point DOP + PVC 116 ℃ 130 ℃ 38 ℃ DEDB + PVC 94 ℃ 100 ℃ 12 ℃ (not turbid) 2, the temperature of the glass transition temperature and flow rate of temperature rise rate temperature Tg Tf ℃ 40% DEDB + PVC 22 ℃ 109 ℃ 5 40% DOP + PVC 34 ℃ 111 ℃ 5 3, the mechanical strength Tensile strength kg/Cm2) Elongation at break (%) Tensile speed mon / ml DOP longitudinal cross 226.4 22 650 281.8 228 50 DEDB longitudinal cross 31526150 297.2 235 504, the dielectric strength DOP + PVC resistivity 7 × 1010ωCm DEDB + PVC resistivity of 7 × 1010ωCm 5, aging test Aging Time (hours) species Kg/Cm2 Elongation% Tensile strength Tensile strength Elongation transverse% 0 DOP DEDB 262.2 281.5 256 268 261.6 280.2 268 276 24 DOP DEDB 254.5 279.1 249 256 258.5 273.4 260 272 48 DOP DEDB 251.5 260.6 239 244 246.1 262.5 240 236 96 DOP DEDB 231.9 242.5 216 224 241 254 226 216 120 DOP DEDB 221 234 215 216 235 240 220 210 6, DEDB following criteria Project Name Index colorless or light yellow color fat content of not less than 98% the proportion of d 10172 ± 0.004 Acid value mgkoH / g is not greater than 0.3 Heating loss (125) 0.5 Flash point (open cup) of not less than 185-195 Chemical Co., Ltd.
