Embodiment 1

[0047] A production process of flame-retardant glass steel pipes, comprising the following technical steps:

[0048] 1) Lining:

[0049] Prepare materials according to the type and specification of the design materials. The materials are stacked neatly, safely and cleanly, and the materials are strictly protected from moisture. The accelerator and curing agent are stored at a distance of not less than 5 meters;

[0050] Remove the sundries on the surface of the mold, make the outer surface of the mold smooth, check whether the structure of the mold is intact, whether the welding seam of the shaft head is open, apply the release wax evenly on the outer surface of the mold, and squeeze repeatedly to make the wax layer on the surface of the mold even , the thickness meets the design requirements, the mold needs to be waxed once when it is used for the first time or used continuously for many times, and the frequency of waxing should be increased when it is difficult to demould; ...

Embodiment 2

[0075] A kind of production technology of flame-retardant glass steel pipe, compared with embodiment 1:

[0076] In step 1), prepare a 200mm film according to the pipe diameter requirements;

[0077] The accelerator is cobalt water, the curing agent is methyl ethyl ketone peroxide, and the resin is selected from unsaturated polyester resin, wherein the lining layer resin is selected from bisphenol A type unsaturated polyester resin;

[0078] The flame retardant is composed of dimethyl methyl phosphate and aluminum hydroxide, wherein the mass ratio of dimethyl methyl phosphate to resin is 12:100, and the mass ratio of aluminum hydroxide to resin is 8:100;

[0079] The mass ratio of accelerator, curing agent, auxiliary agent and resin is 0.3:3:4:100;

[0080] The auxiliary agent is obtained by uniformly mixing nano-silica, acetone, and divinyltetramethyldisiloxane platinum complex in a mass ratio of 1:4:0.2;

[0081] Other steps are the same as in Example 1.

Embodiment 3

[0083] A kind of production technology of flame-retardant glass steel pipe, compared with embodiment 1:

[0084] In step 1), prepare a 100mm film according to the pipe diameter requirements;

[0085] The accelerator is cobalt water, the curing agent is methyl ethyl ketone peroxide, and the resin is selected from unsaturated polyester resin, wherein the lining layer resin is selected from polyester resin or vinyl ester resin;

[0086] The flame retardant is composed of dimethyl methyl phosphate and aluminum hydroxide, wherein the mass ratio of dimethyl methyl phosphate to resin is 8:100, and the mass ratio of aluminum hydroxide to resin is 5:100;

[0087] The mass ratio of accelerator, curing agent, auxiliary agent and resin is 0.3:3:3:100;

[0088] The auxiliary agent is obtained by uniformly mixing nano-silica, acetone, and divinyltetramethyldisiloxane platinum complex in a mass ratio of 1:4:0.2;

[0089] Other steps are the same as in Example 1.

Abstract

The invention discloses a flame-retardant glass steel pipe and its production process, comprising the following technical steps: 1) lining; 2) winding; 3) curing: after the winding is completed, the mold with the pipe is immediately hoisted to the curing station, and Start the spindle to make the mold rotate at a constant speed for curing; 4) Trim: Check the curing degree of the pipe, and when the Barcol hardness of the outer surface of the pipe is not less than 20, trim the socket, trim the socket, and surface treatment; 5) Demoulding: When the pipe When the Barcol hardness of the outer surface is not lower than 25, demoulding is carried out, the burr of the pipe socket is completely cut off, and the burr at the end of the socket is polished, and the resin is evenly applied until it is cured. The glass steel pipe material prepared by the production process of the present invention can ensure the mechanical properties of the glass steel pipe material while exerting the flame retardant effect.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic pipes, in particular to a flame-retardant fiberglass steel pipe and a production process thereof. Background technique [0002] FRP pipe is a kind of composite material, and FRP pipe is a non-metallic pipe with light weight, high strength and corrosion resistance. It is based on resin. Glass fiber is a reinforced material made by a special process. This kind of pipeline has the advantages of corrosion resistance, leakage resistance, heat insulation and so on. It has the advantages of light weight, high strength, long life, strong designability, small fluid resistance, convenient installation, and low comprehensive cost. Can be widely used in petroleum, chemical industry, pharmaceutical, electric power, papermaking, urban water supply and drainage, factory sewage... Due to its unique performance advantages, FRP pipes have been used in aerospace, railways, decorative buildi...
