    • PURPOSE:To uniformly disperse rubber compounding ingredients while preventing them from being spilt and obtain a uniform rubber compound without any cut film pieces left therein, by a method wherein rubber compounding ingredients are packed up by a film of trans-1,4-polyisoprene, and thereafter the ingredients are compounded and kneaded with a rubber. CONSTITUTION:The rubber compounding ingredients such as a vulcanizing agent (vulcanization accelerator), an activating agent and a filler are packed up by a film (preferably 20-100mu in thickness of trans-1,4-polyisoprene [preferably, containing not less than 95% of trans-1,4 bond and having an intrinsic viscosity (at 30 deg.C in toluene) of 1.5-3.5], and the thus obtained packs are compounded and kneaded with a rubber such as a natural rubber or a synthetic rubber to obtain the objective rubber compound.
    • 目的:为了均匀地分散橡胶配混成分,同时防止它们溢出,并且通过其中橡胶配混成分被反式-1,4-聚异戊二烯膜包装的方法获得均匀的橡胶混合物而没有留下任何切割膜片, 然后将成分混合并用橡胶捏合。 构成:橡胶配混成分如硫化剂(硫化促进剂),活化剂和填料由膜(优选20-100μm厚的反式-1,4-聚异戊二烯)(优选含有不少于 95%的反式-1,4-键,其特性粘度(在甲苯中30℃)为1.5-3.5],并将所得包装与天然橡胶或合成橡胶等橡胶混合并捏合 得到目的橡胶组合物。

    • Rheological additive (I) in the form of a preactivated paste, comprises at least one fatty acid diamide (A) introduced in the powder form, it being possible for the powder optionally to comprise, in addition to the diamide, hydrogenated castor oil; and at least one organic plasticizer (B) which is liquid at room temperature. Independent claims are included for: (1) the preparation of (I) comprises progressive dispersing of the diamide in the powder form, in the plasticizer until a homogeneous dispersion is obtained, at room temperature controlled by virtue of regulation of the temperature, and maintaining the homogeneous dispersion obtained during the first step at least one isotherm with a corresponding temperature of 50-120[deg] C, for 1-100 hours; (2) an organic binder composition or pigment concentrate composition or fillers composition, comprises, (I) in addition to the binder, pigment or filler; (3) a process for the preparation of a composition comprising adding (I) to the composition; homogenizing the mixture with an agitator and/or planetary mixer and/or high speed disperser, without having any need, at this stage, to apply an activation treatment; and (4) a coating from paints, or varnishes, or inks, or gel coats, or plastisols based on polyvinylchloride, or a sealant, or a glue, or an adhesive, or a sealer, or a composite, or a molded compound, or an sheet molding composition (SMC)/brittle matrix composite (BMC) laminate, or a cosmetic product, which is obtained from (I).
    • 预活化糊剂形式的流变添加剂(I)包含以粉末形式引入的至少一种脂肪酸二酰胺(A),除了二酰胺之外,粉末还可以包含氢化蓖麻油; 和至少一种在室温下为液体的有机增塑剂(B)。 包括以下的独立权利要求:(1)(I)的制备包括将增塑剂中的二酰胺逐渐分散在增塑剂中直到获得均匀的分散体,在室温下通过调节温度控制,并维持 在第一步骤期间获得的均匀分散体至少一个等温线,相应的温度为50-120℃,持续1-100小时; (2)有机粘合剂组合物或颜料浓缩物组合物或填料组合物,除了粘合剂,颜料或填料外还包含(I) (3)制备组合物的方法,包括向组合物中加入(I); 使用搅拌器和/或行星式混合器和/或高速分散器均匀化混合物,而不需要在该阶段施加活化处理; 和(4)基于聚氯乙烯的涂料或清漆或油墨或凝胶涂层或增塑溶胶的涂层,或密封剂,胶或粘合剂或密封剂或复合材料或模塑料, 或由(I)得到的片状成型用组合物(SMC)/脆性基质复合体(BMC)层合体或化妆品。
