Problems solved by technology

The disadvantages are: (1) it does not have flame retardant performance, and cannot be used as an engineering material with relatively high flame retardant requirements; (2) to obtain corrugated honeycomb composite cardboard products of different specifications, it is necessary to pre-cut corrugated cardboard of various specifications, which requires It is time-consuming, labor-intensive and inconvenient to constantly change the cutting tool and the adjustment of the machine parts. Not only the production efficiency is low, the maneuverability is poor, but also the investment efficiency is low. (3) The thickness of corrugated cardboard is limited. 50mm, no matter how thick it is, the operation is relatively difficult, which also restricts the application of the product, especially as an engineering material; (4) In the industrial production line, the production speed of the front corrugating machine and the follow-up composite machine do not match well.
The production efficiency of existing corrugated cardboard production equipment is very high, but in the subsequent compounding of corrugated cardboard, the efficiency is relatively low, which causes a lot of waste in the feeding rate of the front corrugating machine; (5) corrugated honeycomb The flatness of the composite cardboard surface is not easy to guarantee, and the precision is low

Embodiment 1

[0020] The weight is 150g / m 2 Ordinary corrugated paper with a width of 160cm and modified starch glue are used to make single-sided or multi-layer corrugated cardboard. These cardboards are cut to length into cardboards with a length of 600cm, and then compounded into composites in sequence with glue coating by a gluing machine, with a thickness of 20cm. When the composite thickness cannot be achieved at one time, it can be composited by multiple pieces. For example, 6 composites with a thickness of 20cm are composited into a composite with a thickness of 120cm, and the corrugated honeycomb composite with a thickness of 120cm (thickness) × 600cm (length) × 160cm (width) is fixed in the mold, impregnated In the sodium silicate solution at 40 degrees in Baume, an enhanced waterproofing agent can be mixed as needed. When impregnating, the complex must be completely impregnated in it. The impregnating time is 5-30 minutes, then drip all the excess liquid, enter the drying room, ...

Embodiment 2

[0022] According to the technique of embodiment one, utilize grammage 170g / m 2 The corrugated paper is made of single-sided or multi-layer corrugated board with polyvinyl alcohol adhesive, and then combined into a corrugated honeycomb composite in turn. The complex is impregnated with a fire retardant solution with a weight ratio of PVC liquid resin:triaryl phosphate ester:ammonium molybdate=95:3:2. The technical indicators of corrugated honeycomb composite panels with a thickness of 3cm are as follows: flat compressive strength ≥ 10MPa, oxygen index OI ≥ 32, smoke density level ≤ 50, good water resistance > 2h. Its comprehensive index can reach hexagonal FRP honeycomb, and the comprehensive cost is much lower than that of FRP honeycomb.

Embodiment 3

[0024] According to embodiment one process. The flame retardant uses water-soluble phenolic resin. The drying temperature after impregnation can be set at 100-120 degrees, and after drying for 3 hours, take out the sawing machine and slice. The technical indicators of the obtained corrugated honeycomb composite panel are as follows:

[0025] Flat compressive strength ≥ 8MPa, oxygen index OI ≥ 35, smoke density level ≤ 46, good water resistance > 2h. The fire resistance limit of the interior wall panel made of calcium silicate board or magnesium oxide board with a thickness of 10mm is ≥ 1.2h according to GB / T9978-1999.

Abstract

The process of producing fire retardant honeycomb corrugated paper engineering material includes adhering and compounding several layers of corrugated paper to form one composite body, soaking the composite body with fire retardant, stoving, and cutting to required size in the direction perpendicular to the honeycomb. The production process is simple and has high production efficiency. The fire retardant honeycomb corrugated paper engineering material as one new kind of green engineering may be produced in large scale and used widely.

Description

technical field [0001] The invention belongs to the production technology of flame-retardant honeycomb material. Background technique [0002] Structural composite materials generally used in vehicles, ships, airplanes and other large passenger vehicles and building materials, the primary performance requirement is the fire safety of the material, that is, the flame retardant performance of the material. Corrugated honeycomb material has the characteristics of light weight, excellent mechanical properties, cheap materials, low material consumption, and high yield, and its comprehensive performance is better than that of hexagonal honeycomb products. However, the existing corrugated honeycomb composite paperboard is only used in the packaging industry and is not suitable as an engineering material requiring flame retardancy. Such as the manufacturing process and product of a corrugated honeycomb composite cardboard disclosed in the application number 01129410 and the manufac...
