Embodiment 1

[0019] A preparation method of FRP flame-retardant and anti-corrosion purlin material, the specific method is as follows:

[0020] (1) In terms of parts by weight, 23 parts of monomer dimethyldichlorosilane, 17 parts of diphenyldichlorosilane, 87 parts of phenyltrichlorosilane, 6.7 parts of methyltrichlorosilane and 110 parts of xylene 81.1 parts of xylene and 71.31 parts of water are added to the hydrolysis kettle, and the mixed monomer is added dropwise under stirring. The temperature is controlled at 20 ° C, the dropping time is 5.5 hours, and then the temperature is raised to 120 ° C Continue to react for 1 hour, let stand to separate layers, remove the water in the lower layer, and finally remove the solvent, residual water and low molecular weight substances under reduced pressure to obtain the silicone resin prepolymer;

Abstract

The invention belongs to the technical field of purlines, and particularly relates to a preparation method of a glass fiber reinforced plastic flame-retardant anti-corrosion purline material. A prepared anti-corrosion purline has excellent corrosion resistance, can resist corrosion of various liquid media such as acids, alkalis, organic solvents and salts in different degrees, and is light in weight and strong in strength; the material has the advantages of light weight, strong longitudinal strength and the like, is easy to install, has good resilience force, can greatly prolong the normal service life of a product due to aging resistance, is easy to maintain, and has excellent insulativity; the product does not fade or rust in the use process, does not need paint maintenance, and is suitable for flammable and combustible places due to excellent flame retardance of the adopted material.

Description

technical field [0001] The invention belongs to the technical field of purlins, in particular to a method for preparing a glass reinforced plastic flame-retardant and anti-corrosion purlin material. Background technique [0002] FRP purlins are also called anti-corrosion purlins. First of all, they are purlins, which are used in steel structures with large areas and wide spans such as factory buildings that require fast construction. It is a very important part of the steel structure building. Purlins carry the weight of the roof slab, including the load-bearing generated during the construction of the roof slab, and the load-bearing generated by regular and irregular roof maintenance. The technical indicators of FRP purlins meet the requirements of housing use. When used in corrosive environments, the anti-corrosion performance is several times that of ordinary purlins. Material. Anti-corrosion purlins are widely used in various aspects such as roofs and wall beams suita...
