The invention discloses a synthesis method for waterborne organocilicon-polyurethane block copolymer, comprising steps as follows: reaction is carried out between polyisocyanate and polyol (the polyol comprises the one from the castor oil and carboxyl polyol) to generate isocyanate-terminated polyurethane prepolymer; then chain extension is carried out via amino alkyl polysiloxane; eventually alkaline aqueous solution is adopted for neutralization and dispersion, to prepare aqueous dispersion with excellent dispersion and stability. In addition, the aqueous dispersion is applied as coating for the wood and paper, as finishing agent for leathers and textiles, or as adhesives. Since natural vegetable oil from castor beans is selected and amino alkyl polysiloxane is adopted as the chain extender. The synthesis method for waterborne organocilicon-polyurethane block copolymer has the advantages of remarkably improved hydrophobic property, heat resistance and surface smoothness for the polymer ...

The invention provides a shaft oil stain detergent as well as a preparation method and an application. The shaft oil stain detergent consists of the following components in percentage by weight: 0.2-2% of a surfactant OP-10, 5-10% of a builder STPP, 2-5% of a pH adjusting agent NaOH and the balance of water. The preparation method comprises the following steps: completely dissolving the STTP of the amount into water, adding NaOH of the amount, and dripping OP-10 of the amount, thereby preparing the shaft oil stain detergent. The grease dissolution rate of the shaft oil stain detergent is greater than 90%, and the shaft oil stain detergent has good dispersion and solubilization functions.

The invention discloses a reacted acid online processing system and method in the oil-gas well large-scale acid fracturing flow back process. The system comprises a detection branch circuit, an alkali liquor discharging branch circuit and a control branch circuit. A sensor is arranged in the detection branch circuit. The alkali liquor discharging branch circuit comprises an alkali liquor tank and a flow control device. The alkali liquor tank, the flow control device and an acid liquor flow back channel are sequentially connected. The method comprises the steps that a PH value is detected through the sensor, a control instrument compares the measured value with a set value and controls the opening degree of a flow control valve, and the PH value can be automatically adjusted. According to the reacted acid online processing system and method in the oil-gas well large-scale acid fracturing flow back process, the neutralized mode of manually throwing solid alkali is replaced, the adding amount ...

Method for preparing water-dispersed block polymer flame retardants with phosphorus, silicon and nitrogen and uses thereof

Номер: CN0101333443B

The invention discloses a method for preparing water dispersible macromolecule flame retardant which contains P-block, Si-block and N-block and the application thereof. The flame retardant is produced through the following steps: polyisocyanate and polylols (including phosphoric polylol, carboxylic polylol, polymer polylol and castor oil) react to produce isocyanate-terminated polyurethane prepolymer; then the isocyanate-terminated polyurethane prepolymer is processed with amino silicones for chain extension and finally is neutralized and dispersed by alkali aqueous solution, thus preparing an aqueous dispersion with good dispersivity and stability. The invention is characterized in that the molecular chain of the synthesized flame retardant contains P, Si and N which have auxiliary fire retarding effects, thereby making the flame retardant better in fire retarding effect with no emission of poisonous gas and low amount of smog after burning; the synthesized flame retardant takes water ...
