Embodiment Construction

[0023] The present invention will be further explained below in conjunction with specific embodiments.

[0024] refer to figure 1 , embodiment one

[0025] A method for preparing epoxy emulsion for corrosion-resistant high-pressure pipe yarn is proposed in this embodiment, comprising the following steps:

[0026] S1: Prepare materials, including 100 parts of epoxy resin, 39 parts of polyisocyanate, 19 parts of glycerin, 13 parts of phosphorus pentoxide, 14 parts of additives, 14 parts of grass-wood mixture and 5 parts of rhodium phosphine Complex catalyst, additives include special lime powder and special gypsum powder, grass and wood mixture includes plant ash and plant fiber, epoxy resin is bisphenol A type epoxy resin, which is made by mixing epoxy E51, epoxy E44 and epoxy E20 The ratio of special lime powder and special gypsum powder in the additive is controlled at 45% to 55%: 45% to 55%. The preparation method of special lime powder is to select suitable lime powder an...

Abstract

The invention belongs to the field of epoxy emulsion, particularly relates to a preparation method of epoxy emulsion for corrosion-resistant high-pressure pipeline yarn, and provides the following scheme aiming at the problem that the corrosion cannot be effectively enhanced in the prior art: the preparation method comprises the following steps: preparing materials; comprising 100 parts of epoxy resin, 30-40 parts of polyisocyanate, 15-20 parts of glycerin, 10-14 parts of phosphorus pentoxide, 10-15 parts of an additive, 10-15 parts of a vegetation mixture and 2-5 parts of a rhodium-phosphine complex catalyst, the corrosion resistance of the epoxy emulsion is improved, the alkali resistance of the epoxy emulsion is greatly improved, the epoxy emulsion can be in contact with alkaline substances for a long time without being corroded, and the service life of the epoxy emulsion is prolonged. The epoxy emulsion has the advantages that the epoxy emulsion is modified, the salt fog resistance of the epoxy emulsion is also improved, the epoxy emulsion can only be corroded slowly by salt fog, the resistance of the epoxy emulsion to the salt fog is improved, the scrubbing resistance of the epoxy emulsion is also improved, and the phenomena of separation, falling and the like cannot occur even if the epoxy emulsion is scrubbed repeatedly.

Description

technical field [0001] The invention relates to the technical field of epoxy emulsions, in particular to a method for preparing epoxy emulsions for corrosion-resistant high-pressure pipe yarns. Background technique [0002] The patent with application number CN201710257446.6 discloses a preparation method of water-based epoxy emulsion, and the present invention provides a preparation method of water-based epoxy emulsion. The method comprises the following steps: (1) taking an appropriate amount of epoxy resin and putting it into a reaction container, then adding polyether and a catalyst to the reaction container in sequence, stirring evenly, heating to 30-150° C. and keeping it warm for 1-7 hours; (2 ) Add the remaining epoxy resin to the above reaction vessel, stir evenly, add phosphoric acid at 30-150°C, stir evenly again, keep warm for 0.5-6 hours; (3) cool down to 25-100°C, add water to emulsify That is, the aqueous epoxy emulsion is obtained. The water-based epoxy emu...
