Embodiment 1

[0025] The seepage pipe or film or container for agricultural irrigation comprises: a plasticized molding material matrix 1, an inert filler 2 with a melting point higher than the plasticizing temperature is added to the plasticized molding material matrix, and the inert filler means that it cannot It melts at the processing temperature of the plastic and cannot be fused with the melted plastic to form a homogeneous material. The inert filler is coated in a release agent. The release agent refers to a certain compatibility with the matrix and can The material that forms a layer of liquid film on the surface of the above-mentioned inert filler, this release agent exists in the middle of the two phases of the inert filler phase and the plastic during the subsequent processing, to isolate the two phases and prevent the inert filler particles from directly contacting the plastic material In contact, the spacer dissolves into the matrix material to form a curved leakage channel 3 by...

Embodiment 2

[0027] Water seepage pipes or membranes or containers for agricultural irrigation, the composition of which includes: polyethylene as a matrix, inert fillers with a melting point higher than the plasticizing temperature of polyethylene, such as powdery bentonite, white carbon black, A mixture of one or more substances in activated carbon, calcium carbonate or starch in arbitrary proportions, the inert filler is coated in a release agent, and the release agent has a certain compatibility with the matrix and can be used in the above-mentioned The material that forms a layer of liquid film on the surface of the inert filler, this release agent exists in the middle of the inert filler phase and the plastic phase during subsequent processing, to isolate the two phases and prevent the inert filler particles from directly contacting the plastic material , including a mixture of one or more substances in liquid paraffin, silicone oil or lubricating oil in any proportion. A curved leak...

Embodiment 3

[0029] Seepage pipes or membranes or containers for agricultural irrigation, the composition of which includes: polyvinyl chloride as a matrix of plasticized molding materials, inert fillers with a melting point higher than the plasticizing temperature of polyvinyl chloride, such as powdered A mixture of one or more substances in bentonite, white carbon black, activated carbon, calcium carbonate or starch in any proportion. The inert filler means that it cannot be melted at the processing temperature of the plastic, nor can it be fused with the melted plastic to form a A homogeneous material, the inert filler is coated in a release agent, the release agent refers to a material that has a certain compatibility with the matrix and can form a layer of liquid film on the surface of the above inert filler, this release agent It exists in the middle of the inert filler phase and the plastic phase in the subsequent processing to isolate the two phases and prevent the inert filler part...

Abstract

The invention relates to a seepage pipe, film or vessel for agricultural irrigation and a making method and application thereof. People first use water permeability of pottery clay to sinter permeation irrigation pipes of pottery clay, and then uses a rubber foam technique to manufacture permeation irrigation pipes of rubber, and some people apply a laser perforating method on plastic pipes to produce porous permeation irrigation pipes of plastic. Due to high cost, inconvenient application or blockage often happening during application, the pipes of the types are not popularized or widely applied. The product of the invention comprises a plasticization forming matrix material (1), an inert filler (2) with melting point higher than plasticizing temperature which is added in the plasticization forming matrix material and is wrapped over by a release agent, and a bent seepage channel (3) which bypasses the inert filler and is formed by dissolving the release agent in the matrix material. The weight ratio between the inert filler and the plasticization forming matrix material is 5-30: 100 and the weight ratio between the inert filler and the release agent is 100: 5-10. The product is applied as pipe, film or vessel for agricultural irrigation.

Description

Technical field: [0001] The invention relates to a material for agricultural irrigation, its manufacturing method and application. Background technique: [0002] Irrigation is an eternal theme of agricultural production, and water-saving irrigation has attracted more and more attention in today's world of increasingly scarce fresh water resources. Among many water-saving irrigation methods, infiltration irrigation is considered to be the best water-saving irrigation method and the most beneficial irrigation method for crop growth. In order to solve the manufacture of seepage irrigation pipes, the key material of seepage irrigation equipment, people first used the water seepage properties of ceramics to fire clay seepage irrigation pipes. Later, rubber foaming technology was used to make rubber seepage irrigation pipes, and laser marking on plastic pipes was also used. Hole method to manufacture porous plastic irrigation pipes. However, the above-mentioned types of pipes ha...
