and fourthly, after the concrete is solidified, spraying an enamel glaze layer on the outer surface of the civil air defense door and sintering at high temperature, wherein the enamel glaze layer is prepared from antimony white, kaolin, zirconium oxide, urea and deionized water.

2. the process of manufacturing a lightweight civil air defense door according to claim 1, wherein the reinforcing core layer is a foamed polyester elastomer.

the technical field is as follows:

the invention relates to the field of civil air defense doors, in particular to a manufacturing process of a light civil air defense door.

background art:

the existing civil air defense door is usually a concrete or steel structure and the combination of the concrete and the steel structure, and the civil air defense door is not only heavy, but also has poor strength and short service life.

The invention content is as follows:

the invention aims to solve the technical problem of providing a manufacturing process capable of producing a light civil air defense door with high mechanical strength and long service life.

The technical scheme of the invention is to provide a manufacturing process of a light civil air defense door, which comprises the following steps:

Firstly, rolling the carbon fiber prepreg cloth with the designed spreading layer into a carbon fiber reinforced pipe according to a row-stacking structure sequence, drying, curing and demoulding;

Secondly, arranging the carbon fiber reinforced pipes perpendicular to the reinforcing core layer in a penetrating manner, wherein the lengths of the two ends of the carbon fiber reinforced pipes penetrating through the reinforcing core layer are consistent;

thirdly, manufacturing a civil air defense door template required by design, placing the reinforcing structure formed in the second step into the template, pouring concrete into the template, tamping the concrete to compact the concrete, wherein the concrete is prepared from the following raw materials, by mass, 200 parts of cement, 25 parts of ferric silicate, 60 parts of expansion powder, 15 parts of glass fiber, 10 parts of sodium silicate, 20 parts of titanium dioxide nano powder and 120 parts of water;

and fourthly, after the concrete is solidified, spraying an enamel glaze layer on the outer surface of the civil air defense door and sintering at high temperature, wherein the enamel glaze layer is prepared from antimony white, kaolin, zirconium oxide, urea and deionized water.

The invention has the beneficial effects that: the civil air defense door prepared by the method can keep the impact resistance of the civil air defense door on the premise of greatly reducing the weight, and improve the service life of the civil air defense door, the weight of the civil air defense door is lighter than that of the original concrete civil air defense door by more than 45 percent under the condition of the same thickness, the civil air defense door is dampproof, mildewproof and oxidation-proof, the strength of the civil air defense door is 3 times higher than that of the concrete civil air defense door with the same thickness, and the fatigue life and the impact resistance of the structure are greatly improved.

Preferably, the reinforcing core layer is a foamed polyester elastomer.

the specific implementation mode is as follows:

the invention will be further illustrated with reference to specific embodiments:

A manufacturing process of a lightweight civil air defense door comprises the following steps:

Firstly, rolling the carbon fiber prepreg cloth with the designed spreading layer into a carbon fiber reinforced pipe according to a row-stacking structure sequence, drying, curing and demoulding;

Secondly, arranging the carbon fiber reinforced pipes perpendicular to the reinforcing core layer in a penetrating manner, wherein the lengths of the two ends of the carbon fiber reinforced pipes penetrating through the reinforcing core layer are consistent; the reinforced core layer is a foamed polyester elastomer, and the length of the carbon fiber reinforced pipe is two thirds of the thickness of the civil air defense door;

thirdly, manufacturing a civil air defense door template required by design, placing the reinforcing structure formed in the second step into the template, pouring concrete into the template, tamping the concrete to compact the concrete, wherein the concrete is prepared from the following raw materials, by mass, 200 parts of cement, 25 parts of ferric silicate, 60 parts of expansion powder, 15 parts of glass fiber, 10 parts of sodium silicate, 20 parts of titanium dioxide nano powder and 120 parts of water;
