Abstract
The invention provides a nanocomposite wear-resisting and anti-corrosion coating pipe fitting which comprises a polyethylene pipe fitting and a coating which is coated on the outer wall of the pipe fitting. The coating comprises the following components by weight: 25-60 parts of epoxy resin, 1-15 parts of aluminium oxide nano-powder, 1-30 parts of diluent, 25-40 parts of amine normal temperature epoxy hardener and appropriate amount of coating additives. The nanocomposite wear-resisting and anti-corrosion coating pipe fitting is good in adhesion and significantly strengthens wear-resisting and anti-corrosion performance against the polyethylene pipe fitting, and the wear rate is reduced by more than 15%; and furthermore, the cost of raw material is low, the coating operation is convenient, the coated pipe fitting is better adaptive to the environment and has longer service life and important market value.
Description
Technical field
The present invention relates to a kind of nano combined wear-resisting, corrosion-inhibiting coating pipe fitting.
Background technique
Polyethylene pipe is one of most popular plastic tube in the world, the tenacity excellent of polyethylene pipe, shock resistance, nontoxic, and polyethylene pipe can be easy to be used widely through the molten solder assembling.At present, the pipeline that be used to feed water, buried pipeline all adopts polythene material mostly among the municipal engineering such as combustion gas.Wherein need use a large amount of electric melting pipe fittings, safe in utilization secure for guaranteeing pipeline, the performance requirement of electric melting pipe fittings is higher than the requirement of tubing, particularly the performance of wear-and corrosion-resistant aspect.Their working life of prolongation that paint spraying can be is easily and effectively carried out on the pipe fitting surface, improve their various performances.
The coating that is used for frosting must possess two primary conditions, and at first, coating must have good adhesion to plastic bottom material, and secondly, coating is the corrosion frosting too.Various its structures of different plastics are different with performance, and selectable coating variety is also different, and coating process also varies.At present, also relatively lack with the coating of wear-and corrosion-resistant and the research of application aspect with regard to polyethylene tube.
Summary of the invention
The purpose of this invention is to provide a kind of nano combined wear-resisting, corrosion-inhibiting coating pipe fitting, in order to solve defective and the deficiency that above-mentioned existing technology exists.
For realizing above-mentioned purpose, a kind of nano combined wear-resisting, corrosion-inhibiting coating pipe fitting of the present invention, the coating that it comprises polyethylene tube and is coated on the pipe fitting outer wall;
Said coating is combined by its weight ratio by following component:
Further, the lipophile aluminium sesquioxide nano-powder of said aluminium sesquioxide nano-powder for carrying out surperficial oleophylic modification via stearic acid, particle size range is 10～100nm;
Further; Described coating additive comprises more than one of wetting dispersing agent, levelling agent and foam breaker; Said wetting dispersing agent is that electroneutrality is gathered thiamines and polyester mixture wetting dispersing agent; Described levelling agent is the polyether-modified polysiloxane of non-response type, and described foam breaker is a modified polyorganosiloxane;
Further, said coating comprises 1～6 layer;
Further, during application, the polyvinyl piping materials outer wall is through surface activation treatment, because poly characteristics are that polarity is low, degree of crystallization is high, obtain the good comparison difficulty of filming of adhesion;
Said surface activation treatment is flame treatment, Corona discharge Treatment or plasma treatment;
Further, the application mode is Airless spraying, 60 ℃ of dryings of far infrared collimation method.
A kind of nano combined wear-resisting, corrosion-inhibiting coating pipe fitting provided by the invention, coating adhesion is good, has had significantly for the wear-and corrosion-resistant performance of polyethylene tube and has strengthened; Wear rate reduces more than 15%; And cost of material is cheap, and application is convenient, and the pipe fitting environmental suitability after the application is better; Longer service life has important market value.
