A kind of preparation method of master batch for water conservancy project floating

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...

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.
