Embodiment 2

[0048] The difference between embodiment 2 and embodiment 1 is: its formula is except magnesite powder, brine, modifying agent, also adds glass fiber cloth in the formula by weight ratio 5-20 parts. Fiberglass cloth plays a role in enhancing the strength and toughness of the product. After adding glass fiber cloth to the formula, the strength of the greenhouse skeleton is further increased. Example 3 High-strength composite material greenhouse skeleton with glass fiber cloth and external plastic pipes

Embodiment 3

[0048] The difference between embodiment 2 and embodiment 1 is: its formula is except magnesite powder, brine, modifying agent, also adds glass fiber cloth in the formula by weight ratio 5-20 parts. Fiberglass cloth plays a role in enhancing the strength and toughness of the product. After adding glass fiber cloth to the formula, the strength of the greenhouse skeleton is further increased. Example 3 High-strength composite material greenhouse skeleton with glass fiber cloth and external plastic pipes

[0049] Embodiment 3 is a further improvement on the basis of Embodiment 2: it is to add plastic pipes outside the greenhouse skeleton formed by solidifying the components. First of all, it is beautiful, easy to install and bend, and can protect the proportioning material inside from being weak in case of violent impact. Moreover, the mold can not be taken out during molding, which is very convenient. Forming process

Abstract

The high-strength plastic house skeleton of composite material has the material composition of: magnesite powder in 100 weight portions, baume degree 20-35 magnesium chloride solution 80-95 weight portions and modifier 0.1-1.0 weight portions. The plastic house skeleton produced with the material and through solidification has high strength, long service life and low cost. The forming technological process is also disclosed.

Description

technical field [0001] The invention belongs to the field of chemical materials, and mainly relates to a high-strength composite material greenhouse framework. The invention also discloses a molding process method of the high-strength composite material greenhouse skeleton. Background technique [0002] Greenhouse planting and breeding are important ways for farmers to increase their income at present, but the current lag in the research and development of greenhouse framework materials restricts the development of greenhouse agriculture in China. At present, the most traditional greenhouse materials in the market are bamboo and wood materials, which have short life, low strength and small effective use space. In the past two years, many farmers no longer use bamboo and wood materials, and began to actively seek new materials to update the greenhouses. Metal materials have the disadvantages of corrosion and easy damage to the film, and the cost is high. Contents of the i...
