A container floor and its making method and flow discloses 6 kinds of materials including anti-wear layer, glass fiber layer, bamboo plywood layer, honeycomb structure layer, wooden three-ply board and glass fiber layer, etc. the container floor is glued between layers by glue.
For a long time, no standard for manufacturing and using container bottom boards is available internationally except for the national standard (standard number GB/T19536-2004) of plywood for container bottom boards, which was established in 2004 by China.
The high-performance fiber belongs to the field of new materials, has high strength, high modulus, high temperature resistance, chemical corrosion resistance and other chemical properties, and has the fiber strength of 4127MPa, 3540MPa and 2757MPa, and the lamination strength of 1600MPa, 1500MPa and 1430MPa respectively. The specific gravity of the carbon fiber is less than 1/4 of that of steel, the tensile strength is 12 times that of steel, and the specific strength is 20 times that of iron. The fibers with excellent properties are widely applied to various fields of national economy such as military industry, national defense, large aircraft manufacturing, automobile weight reduction, transportation, environmental protection, medical treatment and health and the like.

The fiber composite material container bottom plate is a whole flexible coiled material or a hard plate, and light fiber materials such as carbon fiber and the like account for about 50-65% of the total weight of the bottom plate.
The manufacturing method of the fiber composite container bottom plate comprises the following steps:
(1) Manufacturing a surface layer, a core layer and a bottom layer;
(2) Dipping or coating the core layer;
(3) Coating a surface layer with a silicone rubber coating;
(4) And compounding the surface layer, the core layer and the bottom layer.

The three-dimensional fabric with the I-shaped section is a double-layer fabric which is formed by three-dimensionally interweaving the warp yarns of the upper layer and the lower layer into a face-to-face type by using two independent weft insertion systems of the upper layer and the lower layer and warp yarns of the upper layer and the lower layer ground weave. The T-shaped section three-dimensional fabric is formed by interweaving two heald frames up and down to form a transverse part, and interweaving the other two heald frames up and down to form an integral part of the T-shaped fabric in the height direction.
The core layer impregnation or coating is a process that the prepared core layer passes through high-performance emulsion or adhesive emulsion to enable the emulsion to enter the gaps among the looser warp multi-layer yarns or yarns of the three-dimensional fabric or warp and weft interweaving points to become a fiber reinforcement, and two methods are used for impregnation or coating.
The core layer impregnation process in the step (2) in the method comprises the following steps: adding distilled water accounting for 20 to 30 percent of the weight of the polytetrafluoroethylene dispersion emulsion with the solid content of 50 to 60 percent, diluting, and adding sodium perfluor nonenoxybenzenesulfonate (OBS) accounting for 0.5 to 1 percent of the total weight to prepare an impregnating solution; the core layer is immersed in the impregnating machine, and is operated at a linear speed of 3-5m/min, the operation time in the impregnating liquid is about 5-20 seconds, and the core layer enters a drying area after being immersed and is dried at the temperature of 120-180 ℃. The soaking time is 1-2 minutes, the soaking temperature is 35-50 ℃, the outlet rolling liquid rate is 110-120%, and the drying temperature is 130-150 ℃.

The pre-prepared silicone rubber coating is placed into a high-level charging basket, a slit or a scraper is adopted to be applied to the upper surface of the non-woven fabric, and the application amount of the emulsion is controlled by the size of the slit or the gap between the scraper and the fabric surface. The quality of the non-woven fabric is 110-450g/m 2 The coating amount of the silicone rubber coating is 80-300g/m 2 The coating temperature is 40-60 ℃, and the thickness of the surface layer is 0.5-10.0mm. In a pair of rollers at the outlet of the coating machine, the upper roller is engraved with diamond or geometric patterns to make the surface of the surface layer have concave-convex patterns so as to increase friction force.
The preparation process of the silicone rubber coating comprises the following steps: the silicone rubber with the solid content of 50 percent is mixed with the xylene solvent, so that the concentration of the silicone rubber emulsion reaches 10 to 15 percent.
The surface layer and the core layer and the bottom layer are compounded by a coating compounding machine by using a foam coating method; wherein, the single-layer sizing amount of the foam coating adhesive is 50-450g/m 2 The speed of the coating compound machine is 10m/min, the pre-baking temperature is 80-90 ℃, and the baking temperature is 130-150 ℃; foam density of the foam generator is 0.15-0.2g/cm 3 Foaming ratio 1: 3-1: 5.

The pre-prepared coating is conveyed to a feeding roller of a coating compounding machine through a pipeline by a foam generator arranged above a pressing roller, is coated on the front surface of a bottom layer material by a feeding roller, and simultaneously enters a roller with a core layer and a bottom layer which synchronously run above the bottom layer material, so that the core layer and the bottom layer are compounded. According to the same method, the other side of the core layer having the primer material compounded and the other side coated with the silicone rubber coating face layer are compounded.
The method for compounding the foam coating is to reduce the use amount of the adhesive in the bonding process, the adhesive is coated on the surface of the bottom layer material in the form of foam with different sizes, and a discontinuous film is formed on the surface of the bottom layer along with the rupture of the foam, so that the aim of compounding is fulfilled.

The regenerated fiber with basically consistent mechanical strength, electromagnetic thermal performance and the like of the production waste materials of carbon fiber manufacturing enterprises and the original fiber is recycled by adopting the high-temperature resistant filter material preferentially. During manufacture, the characteristics of the composite material reinforcement borne by the core layer are fully considered, except the conventional 0 0 90, and 90 0 Is increased by +45 in addition to the yarn arrangement 0 、-45 0 The directional yarns and the fabric sections with different shapes are designed, so that the bottom plate has the structural characteristics of reinforcement in all directions. When the core layer is immersed in polyacrylate emulsion, tension is increased in the running direction and the width direction, and under the condition that yarns in each layer are arranged flatly, the emulsion is enabled to permeate into the core layer uniformly. When polytetrafluoroethylene emulsion is coated, the emulsion is also made to fully infiltrate the gaps between warp and weft interweaving points of the three-dimensional fabric.
