The PPR is modified by the nano alumina, so that the problems of algae growth adhesion in the water body, influence on water quality and pipeline deformation caused by thermal deformation due to the light transmittance of the PPR are solved.
Because the growth of fungi and algae caused by the light transmission of the PPR pipe is mainly generated under the action of ultraviolet light, and the nano aluminum oxide has the function of absorbing the ultraviolet light, the growth of the substances in the pipeline is inhibited, and the aim of improving the water quality is fulfilled, particularly for household pipes with low water consumption and outdoor pipelines. Meanwhile, for the areas with high fluorine content in water, the nano-alumina also has the function of adsorbing and removing fluorine. Meanwhile, the nano-alumina has the characteristics of stable crystalline phase, high hardness, reinforcement and toughness, and good dimensional stability, improves the temperature resistance of the product, and achieves the purpose of reducing the thermal deformation.
In addition, the compatibility problem of the PPR resin, the nano-alumina and the color master batch is solved by the formula of the technical scheme, the inner wall of the obtained PPR pipe has better smoothness, the flow resistance is reduced, the deposition of small micro-particles in water is reduced, and the production and the attachment of fungi and algae are also reduced.
Further, the particle size of the nano-alumina is 30-80 nm.
Further, the nano alumina is gamma-type alumina.
Further, the processing aid is a titanate coupling agent, an aluminate coupling agent or a mixture thereof.
Next, the method for preparing a nano-modified PPR water supply pipe according to the second aspect of the present invention is described, which comprises the following steps:
according to the components and the weight ratio of the first aspect of the invention, PPR resin, nano-alumina, color master batch and processing aid are sequentially added into a mixer for stirring, and the stirring speed is 300r/min-500 r/min; stirring at 60-70 deg.C for 10-20min, extruding the mixture with single screw extruder, vacuum cooling, drawing, and cutting to obtain the PPR water supply pipe.
Further, the barrel temperature of the screw extruder was 240-260 ℃.
Example 1: a nano-modified PPR water supply pipe:
sequentially adding 100 kg of PPR resin, 2 kg of color master batch, 5 kg of gamma-type nano alumina and 1 kg of titanate coupling agent into a mixer for stirring at the stirring speed of 300-500 r/min; stirring at 65 ℃ for 15min to obtain a mixture, performing extrusion molding by using a single-screw extruder with a barrel temperature of 240-260 ℃, performing vacuum cooling, traction and cutting by using a power supply to obtain the nano-modified PPR water supply pipe.
Example 2: preparation of a nano-modified PPR water supply pipe:
sequentially adding 90 kg of PPR resin, 1 kg of color master batch, 1 kg of gamma-type nano alumina and 0.2 kg of titanate coupling agent into a mixer for stirring, wherein the stirring speed is 300r/min-500 r/min; stirring at 60 ℃ for 10min to obtain a mixture, performing extrusion molding by using a single-screw extruder with a cylinder temperature of 240-260 ℃, performing vacuum cooling, traction and cutting by using a power supply to obtain the nano modified PPR water supply pipe.
