Production method of agricultural greenhouse framework

Abstract

The invention discloses a production method of an agricultural greenhouse framework. According to the production method, a metal material is taken as a framework lining, and conveyed into a co-extrusion mould, the material extruded by a plastic extruder and a framework basic material are synchronously conveyed onto a sizing mould and a traction machine, and the agricultural greenhouse framework is obtained through co-extrusion, traction, cooling and sizing, and cutting, wherein the metal material can be iron wires, steel wires, cold-rolled round steel or flat iron; the basic material is produced by mixing the following components in parts by weight: 100 parts of plastic, 30-50 parts of plant fiber powder, 3-5 parts of a heat stabilizer, 5-10 parts of a plasticizer, 1-3 parts of a lubricant, 5-10 parts of a modifier ACR-401, 0-3 parts of a compatilizer, 1-3 parts of a coupling agent, 0.5-3 parts of a foaming agent, 3-10 parts of a foaming regulator ZB-530, 10-20 parts of a nucleating agent and 10-20 parts of an inorganic material, and then granulating the components; the inorganic material is the combination of magnesium chloride and magnesium oxide. According to the production method disclosed by the invention, the operation is simple and easy and the cost is low, and the produced greenhouse framework is good in bending resistance and compression resistance.

Description

technical field [0001] The invention relates to a manufacturing method of an agricultural greenhouse framework, which belongs to the technical field of modern agricultural facilities. Background technique [0002] The existing agricultural greenhouse skeletons mainly include the following types: (1) Bamboo and wood skeletons are low in cost, but their bearing capacity, wind resistance, and compression resistance are poor, and they are easy to rot and insects, and are limited by natural resources; (2) )Steel steel and galvanized pipe skeletons are sturdy and durable, but they are inconvenient to assemble and disassemble and the cost is high; The disadvantages of bone fracture and collapse; (4) the cement concrete skeleton is fastened and durable, but it is bulky and cannot be disassembled, and it is easy to scratch the film covered on the greenhouse; (5) the magnesite skeleton is strong and durable, but the manufacturing process is complicated. Periodic long, and easy to tid...

[0002] The existing agricultural greenhouse skeletons mainly include the following types: (1) Bamboo and wood skeletons are low in cost, but their bearing capacity, wind resistance, and compression resistance are poor, and they are easy to rot and insects, and are limited by natural resources; (2) )Steel steel and galvanized pipe skeletons are sturdy and durable, but they are inconvenient to assemble and disassemble and the cost is high; The disadvantages of bone fracture and collapse; (4) the cement concrete skeleton is fastened and durable, but it is bulky and cannot be disassembled, and it is easy to scratch the film covered on the greenhouse; (5) the magnesite skeleton is strong and durable, but the manufacturing process is complicated. Long period, and prone to moisture

In recent years, the new wood-plastic greenhouse framework has good waterproof, fireproof, moth-proof, acid and alkali resistance and wear resistance, but the existing wood-plastic framework has low toughness and poor load-bearing capacity.
