Problems solved by technology

From the point of view of the direct cause, the leakage of the expansion joint is due to the fact that the inner skin material is not resistant to acid corrosion or the screws that fix the skin during installation and operation are loosened due to vibration and the accumulated acid corrodes the screws, etc., but the real problem lies in this Conventional expansion joints cannot solve the problem of flue gas leakage at all from the design, causing major economic losses to the owners

preparation example Construction

[0045] In the present invention, the above-mentioned method for preparing the flame-retardant glass-reinforced steel material slab for manufacturing the expansion joint comprises the following steps:

[0046] First spray the base coat to the surface of the model, then spray the structure layer on the side of the base coat away from the model, and then spray the top coat on the side of the structure layer away from the base coat to obtain the plate layer.

[0047] The method for preparing the primer layer is as follows: mixing the first solvent-free mixed resin, the curing agent and the first flame retardant under ultrasonic conditions to obtain the primer layer. When preparing the undercoating, it is carried out under ultrasonic conditions, which is prone to molecular vibrations. The mixing of the curing agent, the first solvent-free mixed resin and the first flame retardant is more uniform, so that it can block the acid liquid on the undercoating, and the resistance Corrosion...

Embodiment 1

[0056] The curing agent of 3kg, the first solvent-free mixed resin of 10kg and the first flame retardant of 2kg are ultrasonically mixed to obtain the primer layer;

[0057] After mixing 20kg of glass fiber and 5kg of carbon fiber, pour 4kg of curing agent and 15kg of the second solvent-free resin and mix at a temperature of 80°C and a pressure of 1.0MPa to obtain a structural layer;

[0058] Mix 10kg of the third solvent-free mixed resin, 3kg of nano wear-resistant materials, 5kg of additives and 2kg of accelerators at 120°C for 0.5h, then add 2kg of UV anti-ultraviolet agents, 4kg of second flame retardants and 3kg The curing agent is mixed to obtain the top coat;

[0059] First spray the base coat to the surface of the model, then spray the structure layer on the side of the base coat away from the model, and then spray the top coat on the side of the structure layer away from the base coat to obtain the plate layer.

Embodiment 2

[0061] 5kg of curing agent, 20kg of the first solvent-free mixed resin, 5kg of the first flame retardant and 3kg of latex were ultrasonically mixed for 5 minutes under the condition of ultrasonic power of 200w to obtain the primer layer, wherein each ultrasonic The time is 10s, and the interval between two adjacent ultrasounds is 5s;

[0062] Mix 30kg of glass fiber, 10kg of carbon fiber and 3kg of nano-inorganic material, pour 20kg of the second solvent-free resin and 6kg of heat-conducting material, mix for 2 hours at a temperature of 100°C and a pressure of 1.2MPa, and then add 6kg of The curing agent obtains the structural layer;

[0063] Mix 15kg of the third solvent-free mixed resin, 5kg of nano wear-resistant materials, 10kg of additives, 5kg of accelerators and 3kg of antioxidants in a mixer at 180°C with a stirring speed of 200r / min for 1h and then add 3kg The UV anti-ultraviolet agent of 5kg, the second flame retardant of 5kg, the curing agent of 5kg and the polishi...

Abstract

The invention provides an inflaming retarding fiberglass material plate layer for manufacturing expansion joints and a preparing method and application of the inflaming retarding fiberglass material plate layer, and belongs to the technical field of composite materials. A bottom coating comprises a curing agent, first solvent-free mixed resin and first fire retardant. A structure layer comprises glass fiber, carbon fiber, second solvent-free mixed resin and a curing agent. A face coating comprises a nano abrasion resisting material, a UV ultraviolet screening agent, an additive, accelerant, third solvent-free mixed resin, second fire retardant and a curing agent. According to the preparing method, the bottom coating is sprayed to the surface of a model firstly, the structure layer is sprayed to the face, away from the model, of the bottom coating, then, the face coating is sprayed to the face, away from the bottom coating, of the structure layer, and the plate layer is obtained. The plate layer has good tenacity, meanwhile, the mechanical performance and the heat resisting performance are not changed, the oxygen index is very high, the flame spreading speed is very low, and self-extinguishment performance is achieved; and abrasion resisting performance and inflaming retarding performance are achieved, strength is high, the inflaming retarding fiberglass material plate layer canbe used for preparing various expansion joints, and the requirements of users are met.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a flame-retardant fiberglass material plate used for manufacturing expansion joints, its preparation method and application. Background technique [0002] In recent years, flue gas leakage accidents of non-metal expansion joints (skin) of flue gas emission equipment in thermal power plants have occurred frequently. From the point of view of the direct cause, the leakage of the expansion joint is due to the fact that the inner skin material is not resistant to acid corrosion or the screws that fix the skin during installation and operation are loosened due to vibration and the accumulated acid corrodes the screws, etc., but the real problem lies in this Conventional expansion joints cannot solve the problem of flue gas leakage at all from the design, causing major economic losses to the owners.
