Problems solved by technology

In the construction process of water conservancy projects, engineering floats are a commonly used tool, but the engineering floats in the prior art are often made of foam materials or ordinary PVC materials, and the floats will absorb water and become heavier after a long time, and the buoyancy is greatly increased. The bottom is easy to grow some planktonic algae, etc., and it needs special cleaning. The foam material is also easy to be pinched off piece by piece by fish, shrimp, crabs, etc. in the sea.

Embodiment 1

[0018] A method for preparing a masterbatch for water conservancy engineering floats, comprising the following steps:

[0019] (1) In parts by weight, 34 parts of zinc nitrate hexahydrate and 21 parts of sodium metavanadate were added to 55 parts of deionized water, and the mixture was added to a stainless steel reactor, and the temperature of the reaction was controlled to be 110°C. After holding the reaction for 4 hours, cool to room temperature, centrifuge to obtain the precipitate, dry the precipitate, and calcinate at 650°C for 30 minutes to obtain nano-zinc vanadate;

[0020] (2) In parts by weight, 55 parts of N-isopropylacrylamide and 8 parts of trifluoroethyl acrylate were added to the reaction vessel, and then 34 parts of deionized water, 1 part of emulsifier, 2 parts of Azobisisobutyronitrile, 9 parts of nano-zinc vanadate, 1 part of organic pigment toner (color can be adjusted according to needs), after mixing and stirring evenly, raise the temperature of the mixtu...

Abstract

The invention discloses a preparation method of master batch for a water conservancy project buoy. The method comprises the following operation steps of (1) adding zinc nitrate hexahydrate and sodiummetavanadate into deionized water; adding a mixture into a stainless steel reaction kettle; performing reaction to obtain nanometer zinc vanadate; (2) adding N-isopropylacrylamide and trifluoroethyl acrylate into a reaction container; then, adding deionized water, emulsifiers, azodiisobutyronitrile, nanometer zinc vanadate and organic pigment powder into the container to obtain gel microspheres; (3) adding polyethylene masterbatch, antioxidants and inorganic filling materials into an extruding machine for extrusion reaction; adding the gel microspheres into a plasticization section of the extrusion machine; performing extrusion, granulation and cooling to obtain the master batch for the water conservancy project buoy. The water conservancy project buoy prepared by the master batch has theexcellent stain resistant performance, and cannot easily generate the water absorption weight increase and buoyancy reduction phenomena in the use process; the service life of the project buoy can beeffectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering appliance preparation, and in particular relates to a method for preparing master batches for water conservancy engineering floats. Background technique [0002] Due to the lack of water resources in our country and the uneven distribution of water resources per capita, water resources themselves are the most important resources in human production and life. This requires our country to continuously build water conservancy projects to ensure the existence of water resources. It better meets the needs of human production and life and the development of social economy, and at the same time effectively prevents natural disasters such as floods and droughts. Water conservancy projects can effectively control and allocate surface water and groundwater, and truly realize the elimination of harm and prosperity. Therefore, ensuring the quality and safety performance of water conserva...
