Description
Technical Field
The invention relates to the technical field of manufacturing processes of automobile container bottom plates, in particular to a process for vacuum filling of a container bottom plate.
Background
The existing container bottom plate mainly uses a bamboo plywood with the thickness of 15 mm-18 mm and a steel plate with the thickness of 3 mm-4 mm. Bamboo plywood: drying, dehydrating, layering, pressing and forming, dividing into required specification and size according to the size of a carriage, and finally connecting the required specification and size to a carriage framework by punching riveting or countersunk bolts; steel plate: the surface of the container is subjected to anticorrosion treatment by using a coating through an embossing steel process, and finally the container is connected to the container framework in a welding mode.
The steel plate is used as a bottom plate of the cargo box, so that the self weight of the vehicle body is increased, and the energy conservation and emission reduction are not facilitated, for example, in a 4.2-meter compartment, the area of the bottom plate of the cargo box is 8.3 square meters, the steel plate is used as the bottom plate of the cargo box, and the weight of the bottom plate is 195.5 kg-260 kg (the thickness is 3-4 mm); in addition, the surface of the steel plate is sprayed with corrosion resistance, after goods are rubbed, the coating is easy to fall off, the bottom plate is easy to be corroded, and the service life is influenced. The bamboo plywood container bottom plate is lighter than a steel plate, but still about 110kg, and is arbitrarily heavy in the six national standards; the bamboo plywood has high water absorption rate which can reach 80-100 percent, and the weight of the bamboo plywood is basically not different from that of the steel plate after water absorption, so that the weight reduction effect is not achieved; after the bamboo plywood absorbs water, layering and internal mildewing are easy to occur, the strength of the bamboo plywood is reduced, the service life is not long, and even safety risks exist.
Disclosure of Invention
The invention aims to provide a process for pouring a container bottom plate in vacuum, which aims to solve the problems of large weight and low strength of the container bottom plate in the prior art.
In order to achieve the above object, the basic scheme of the invention is as follows:
a process for vacuum infusion of cargo box floors comprising the steps of:
a: treating the mould, namely smearing a release agent in the mould and cleaning the surface of the mould;
b: particle spraying, wherein mineral particles are uniformly sprayed on the surface of a die;
c: laying, cutting the fiber and laying on a mould to ensure that the fiber is smooth and has no wrinkles;
d: building vacuum, and building a vacuum environment in the mold, wherein the vacuum degree is more than 98.5 percent;
e: resin infusion, namely setting the resin dosage according to the fiber content of 60-70% of product fibers, and injecting resin, a curing agent and color paste into a mold;
f: curing;
g: demoulding when the Babbitt hardness of the product reaches more than 20 bar;
h: cutting, namely cutting the product according to the size of the bottom plate of the container;
i: and (7) packaging and warehousing.
Further, in the step b, the mineral particles are uniformly sprayed on the surface of the die to generate a mixture of 30-500 meshes.
Further, in the step d, the combination of the flow guide net, the demolding cloth, the vacuum bag, the ohmic tube and the adhesive tape is utilized to ensure the vacuum degree in the mold.
Further, in the step e, the curing agent, the color paste and the resin are in the following mixture ratio: the curing agent content is 3-50%, the color paste content is 1-5%, and the resin content is 45-96%.
Further, in the step f, the mold is heated to accelerate the curing of the product.
The beneficial effect of this scheme: (1) the packing box bottom plate light weight of this scheme excels in, and the packing box obtains heavy effect of subtracting by a wide margin to 4.2 meters's packing box is taken as an example: the weight of the container is reduced by more than 1305.5kg compared with the bottom plate of the steel container, the weight reduction range is up to more than 69.3%, and the weight of the container is reduced by more than 45kg compared with the bamboo plywood container, and the weight reduction range is 41%.
(2) The container bottom plate of this scheme is splendid for the corrosivity problem is solved to the steel bottom plate, has solved for bamboo plywood container bottom plate who is afraid of, moisture absorption, layering, the not long problem of mouldy life, has improved container bottom plate's life and security.
