Problems solved by technology

[0002] At present, most of the skeleton structures of agricultural greenhouses are made of welded steel bars and concrete purlins. Among them, the skeleton structures made of welded steel bars have poor corrosion resistance and high corrosion costs. Long service life and potential threats; Concrete purlins are heavy, inconvenient to install, low in strength, and pose potential safety hazards

Abstract

The invention discloses a flame-resistant, corrosion-resistant, light-weight and high-impact composite material purline for an agricultural greenhouse. According to the technical scheme, the composite material purline is characterized by being prepared from the following raw materials in parts by weight: 30 to 35 parts of unsaturated resin, 10 to 15 parts of low shrinkage agent, 10 to 20 parts of high-impact SBS, 20 to 30 parts of filling, 20 to 30 parts of enhanced fiber, 1 to 2 parts of solidifying agent, 1 to 2 parts of demolding agent, 40 to 60 parts of filling material, 5 to 8 parts of flame retardants, 1 to 2 parts of process additive and 1 to 2 parts of accelerating agent.

Description

technical field [0001] The invention relates to the field of purlin formulations used in agricultural greenhouses, in particular to a composite material purlin formulation for agricultural greenhouses with flame retardancy, corrosion resistance, light weight and high impact resistance. Background technique [0002] At present, most of the skeleton structures of agricultural greenhouses are made of welded steel bars and concrete purlins. Among them, the skeleton structures made of welded steel bars have poor corrosion resistance and high corrosion costs. The service life does not pose a potential threat; the concrete purlin is heavy, inconvenient to install, low in strength, and has potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a new type of composite material purlin formula for agricultural greenhouses with flame retardancy, corrosion resistance, light weight and high impact resistance. [0004] The technica...
