The invention discloses an organic silicon potting adhesive with a high heat conduction capacity. The curing time of the additive type organic silicon potting adhesive with a high heat conduction capacity can be controlled by the temperature and the amount of the catalyst. The condensate has good mechanical and electrical properties, especially outstanding cohesive strength, high and low temperature resistance and radiation resistance. The inventive heat-conducting organic silicon potting adhesive includes component A and B: said component A is mixed by following parts by weight: 100 shares of organic silica-base adhesive, 10-80 shares of heat-conducting filling, 3-20 shares of reinforced-filling, 1-10 shares of catalyst; said component A is mixed by following parts by weight: 100 shares of organic silica-base adhesive, 10-80 shares of heat-conducting filling, and 1-10 shares curing agent.

The invention belongs to the technical field of textiles, and particularly relates to a stock solution coloring polyester fiber and a preparation method thereof. The preparation method comprises the following steps: (1) adding a coloring agent into carrier polyester polyhydric alcohols, and preparing into uniform coloring mother solution; (2) adding the coloring mother solution into a polyester oligomer, uniformly mixing, and successively carrying out pre-condensation reaction and final condensation reaction in a condensation system to obtain coloring polyester melt; and (3) spinning and stretching the obtained coloring polyester melt, and obtaining the stock solution coloring polymeter fiber. The coloring agent is uniformly scattered in a polyester component, so that the compatibility problem of the polyester component and the coloring agent carrier can be effectively solved, the influence of the coloring agent and a carrier thereof on the spinning performance of the coloring polyester melt can be eliminated, and the prepared stock solution coloring polyester fiber is high in content of coloring agent, stable in quality, free from color difference, soft in hand touching, and goodin mechanical performance.
