摘要： An interior trim panel comprises a flexible polyurethane skin layer, an intermediate resilient polyurethane foam layer and a rigid polyurethane foam substrate. The flexible polyurethane skin layer and intermediate resilient polyurethane foam layer are formed as an expanded thermoplastic urethane (TPU) shell in a slush molding process. The rigid polyurethane foam substrate is then foamed in place on the shell in a substrate forming mold. This produces an environmentally friendly, long lasting interior trim panel that can be manufactured economically without any need for plasticizers or adhesive coatings.

摘要： A quasi-prepolymer-type urethane foam for a reaction injection molding (RIM) system comprises, for the polyol side, a blend of a long-chain polyol with a short-chain diol and/or triol and an organometallic catalyst and, for the prepolymer side, a unique high--27 to 31% --free NCO quasi-prepolymer made by reacting an essentially pure MDI with a selected low molecular weight (240 to 1500) polyol having a functionality of about 2.7 to 3.3. The selected low molecular weight polyol is specifically a polyether polyol (i.e. a polyoxpropylene and/or ethylene polyol) initiated with TMP, hexanetriol, glycerine or other suitable polyol. The quasi-prepolymer, while having the expected high reactivity, surprisingly gives good rapid cures in less than 2 minutes. The resulting urethane foam is characterized by its excellent low temperature properties, especially -20% F cold flexibility and -20% F dart impact. The quasi-prepolymer storage stability can be greatly improved by the inclusion of a small amount of a liquid MDI.
摘要翻译：用于反应注射成型（RIM）系统的准预聚物型聚氨酯泡沫体包括多元醇侧，长链多元醇与短链二醇和/或三醇和有机金属催化剂的共混物，对于预聚物侧，通过使基本上纯的MDI与官能度为约2.7至3.3的选定的低分子量（240至1500）多元醇反应制备的独特的高27至31％的NCO准预聚物。选择的低分子量多元醇特别是由TMP，己三醇，甘油或其它合适的多元醇引发的聚醚多元醇（即聚氧丙烯和/或乙烯多元醇）。准预聚物虽然具有预期的高反应性，但令人惊讶地在不到2分钟的时间内提供了良好的快速固化。所得聚氨酯泡沫的特征在于其优异的低温性能，特别是-20％F冷柔性和-20％F飞镖冲击。通过加入少量的液体MDI可以大大提高准预聚物的储存稳定性。

摘要： A solvent flush reaction injection molding mixhead has a mixing chamber with a solvent inlet port in one end and a chemical outlet port in an opposite end. A pair of hydraulically operated chemical injectors are connected to the mixing chamber between the solvent inlet port and chemical outlet port to inject liquid reaction molding chemicals at high pressure through injector ports into the mixing chamber. The mixed chemicals are delivered through the chemical outlet port to a spray wand on the mixhead for application to a mold surface or an object requiring a foam coating. A flush valve is associated with the solvent inlet port and is moveable from a closed position to block the solvent inlet port while the chemicals are injected into the mixing chamber, and an open position where liquid solvent under a high pressure is supplied through turbulator ports into the mixing chamber to clean and flush any remaining mixed chemicals from the flush valve, the mixing chamber including the chemical injector ports, and the spray wand.

摘要： A method and apparatus are disclosed for making preforms from a fibrous material such as glass fibers. The apparatus includes a porous mold form that, in carrying out the method, is attached over the open face of a charge box. The charge box and mold form are then rotated as a single unit to dump glass fibers or other fiberous reinforcement held in the charge box onto the mold form. Air is drawn through the porous mold form to thereby retain a layer of the glass fibers against the mold form. The mold form and charge box are rotated back to their initial position and then disconnected. A binder is sprayed onto the glass fibers if not otherwise already applied thereto. The binder is then cured, resulting in a unitary glass fibers preform.

摘要： A polyurethane RIM system has at least two molding stations. The reactants are brought to the mixheads as three separate streams. One stream contains the isocyanate, the second stream contains some of the polyol, the chain extender and crosslinker and a third stream contains additional amounts of the polyol, along with what additives might be desired. At each mixhead the proportions of ingredients are controlled to give an isocyanate index of about 100, but the ratio of one polyol stream to the other is regulated to control the flex modulus and other properties of the molded product as may be desired. In this way, one source of supply can be used to feed several molding stations, each of wich may produce a product of different physical properties and thus of different costs.

摘要： An improved polyurethane RIM process using a polycarboxy-functional alkyl siloxane as an internal release agent characterized by:(1) Tool break-in or preconditioning with siloxane treatment of the surfaces;(2) Supplying the siloxane to the mix head as a third stream when necessary to prevent undesired side reactions;(3) Using a minimal amount of siloxane that is inadequate for mold release in the absence of the tool preconditioning;(4) Adjustment of catalyst package to counter the inhibiting effects of the siloxane.The use of a bare minimal amount of siloxane prevents excess siloxane from appearing in the surface of the article and causing subsequent paint wet-out and like difficulties. The third stream isolating of the siloxane prevents its carboxy-functional groups from reacting with the prepolymer or with other ingredients that may be carried in the polyol blend.
摘要翻译：使用聚羧酸官能的烷基硅氧烷作为内部脱模剂的改进的聚氨酯RIM方法，其特征在于：（1）通过表面的硅氧烷处理的工具断裂或预处理; （2）当必要时将硅氧烷作为第三流供给到混合头以防止不期望的副反应; （3）在不存在工具预处理的情况下，使用不足以脱模的最小量的硅氧烷; （4）调节催化剂包装以抵消硅氧烷的抑制作用。使用极少量的硅氧烷可防止多余的硅氧烷出现在制品的表面，并导致后续的油漆变湿和类似的困难。硅氧烷的第三流分离防止其羧基官能团与预聚物或可与多元醇共混物中携带的其它成分反应。
