Nontoxic and impact-free water supply pipe

Abstract

In order to overcome the problem of weak tap-water pipes recuperation capability, weak straight performance and pipes are different to be connected through binder caused by soft PE material quality and the problem of PVC material quality is harmful for human body, the invention provides shockproof tap-water pipe without toxicity. In the method, the inner layer (10) of tap-water is extruded and shaped by adding 125-145% nano calcium carbonate according the weight ratio of PE resin as 100, the outer layer (20) is extruded and shaped by said PVC resin, then one tap-water pipe is completed, said nano calcium carbonate can eliminate the heat contraction percentage different between heat PE resin and the PVC resin to realize compact forming. The characteristics are: the PE inner layer does not generate any harmful materials such as dioxin so it is innocuous for human body; used nano calcium carbonate increases the durability, anti-bending strength and anti-distortion strength of pipes, overcomes the problem of it can be press-formed caused by heat contraction percentage different between two materials, and reaches the effect of non-toxicity and shock resistance.

Description

Technical field: [0001] The invention relates to the field of pipe manufacturing, in particular to non-toxic and impact-resistant tap water pipes. Background technique: [0002] Generally speaking, the tap water pipes that supply drinking water are made of PVC and PE and PP materials. Although PVC water pipes have strong bending strength and water pressure resistance, PVC material has the problem of adding stabilizers that are harmful to the human body during the raw material blending process; in the case of PE water pipes, the softness of the resin leads to the water pipe It has poor resilience and poor straightness, and it is difficult to connect water pipes with adhesives. Although the heat fusion method is used to connect these PE water pipes, this combination method is more complicated, and there are problems in connection quality and construction that are difficult to implement. Summary of the invention: [0003] The purpose of the present invention is to overcome the prob...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems that the PVC material is harmful to the human body and the softness of the PE material causes the poor recovery ability and straightness of the water pipe, and the problems that it is difficult to connect the water pipes with adhesives, and provides a non-woven fabric. Toxic and impact-resistant tap water pipe, the inner layer (10) extruded by adding 125-145% nano-calcium carbonate to the tap water pipe according to the weight ratio of PE resin as 100 and the outer layer (20) extruded by using the PVC resin ) into a method for a water pipe (100), the above-mentioned nano-calcium carbonate can eliminate the difference in heat shrinkage between the PE resin and the PVC resin to achieve compact molding
