Problems solved by technology

[0004] The above-mentioned existing technology can start from the production of single-sided corrugated to the terminal production of corrugated honeycomb composite panels, and the entire production line can be completed in one go, but there are also the following problems: First, the production efficiency is not suitable for the production of building materials with a height of 50mm to 100mm, and is not suitable for use as Thick plates for partition walls, etc.
Generally, the production speed of single-sided corrugated board gluing and slitting is within 20m / min, and the drying speed of the board core is also very slow. It is very difficult to press and dry when producing products with a thickness of more than 50mm, the drying energy consumption is large, and the heat energy utilization rate is low.
However, engineering and building materials are mostly between 50 and 120mm, so the existing technology is not suitable for making large-scale materials for engineering
The second is that there are unreasonable mechanical structures, too many complete machine processes, and poor energy efficiency and synchronization, which affect the development and promotion of products.
Third, it belongs to the single-station production line, and the efficiency is relatively low
Fourth, the flame retardant performance is poor
Several important indicators required for general engineering paper materials are flame retardancy, fire prevention, mildew resistance, mechanical strength, bending load capacity, etc. Therefore, corrugated honeycomb composite materials made by existing technologies are mainly used in pallets and packaging industries , not suitable as engineering material

Embodiment 1

[0052] The working width of single-faced corrugated cardboard is 1.6m, made of 170g / m2 high-strength corrugated paper, the corrugation pitch is 5mm high, the modulus is 8.4mm, rolled into a single-faced corrugated roll paper with a diameter of 2.5m, and then the roll paper is rolled Put it into the corresponding permeable cage mold, immerse it in the prepared boron salt or ammonium salt water-based flame retardant dipping pool, drip off the flame retardant after soaking, and put it in a drying room to dry, the room temperature is 40 ~ 200 ℃, the most Good natural or forced convection along the corrugated honeycomb holes. The drying room is equipped with a moisture exhaust fan and a temperature control system. When the room temperature is 85~95℃, the drying time is generally 3~4 hours, and the moisture content is 8~13% (mass percentage). ).

[0053] When the temperature of the roll paper impregnated with flame retardant is above 20℃ in summer, it can be dried naturally in the open ...

Embodiment 2

[0060] According to the same production process as in Example 1, the flame retardant is composed of 5-8% ammonium sulfate, 5-6% sodium tetraborate, 4-5% ammonium molybdate and the balance of water in terms of weight percentage.

[0061] The fireproof glue is composed of 80-90% sodium silicate with a Baume degree of 35-60°C, 5-15% starch derivatives, 1-1.5% sodium stearate and 3-5% ethylene glycol according to weight percentage.

[0062] As the adhesive, commonly known products are used.

[0063] The thickness of the corrugated honeycomb composite is 100mm and the density is 200kg / m3. Test plane compressive strength 3.1mpa, thermal conductivity: 0.055W / M·K, sound insulation RW≥36dB, in line with the A-level (sandwich) non-combustible material GB8624 standard.

Embodiment 3

[0065] According to the process of Example 1, the flame retardant is composed of ammonium chloride 3-6%, ammonium molybdate 4-5%, ammonium polyphosphate 4-8%, calcium propionate 2-3% and the balance in weight percentage. Water composition.

[0066] The fireproof adhesive is composed of sodium silicate 85-98%, glycerol 1-14% and sodium stearate 1-1.5% by weight percentage.

[0067] A publicly-known product is used as the adhesive.

[0068] Using the prepared corrugated honeycomb composite to produce the wooden fire door, its thickness is 50mm. The main technical indicators: fire resistance rating ≥ 1.2h, composite material is A2 grade (composite sandwich material GB8624-97), flat compressive strength ≥ 2.5mpa , Thermal conductivity: 0.068W / M·K.

Abstract

The invention is concerned with production method of corrugated honeycomb with flame-retarded, fireproofing and anti-fungal function for engineering. It relates to multi-position roll putting framework having at least two layers of roller axis on paper setting rack with some corrugated web rollers with flame-retarded function set on it, leading equipment, multi-position wrapping glue equipment and each layer of it made up of upper and lower gelatinizing roller and glue spraying head corresponding to corrugated surface, multi-position drying equipment, multi- position bar cutting equipment, gathering barrier group, complex drying equipment, cutting equipment and plate spelling equipment. The complex body of corrugated honeycomb beehive disposed by flame-retarded and wrapping fireproofing glue and accords to the standard for engineering with A level non-burning stuff standard. It has multi-position with high production and high speed and effect. The erect muscle structure has high mechanics intension and resist-bending load ability, and the structure of corrugated honeycomb is orderly with good capability.

Description

Technical field [0001] The invention belongs to the manufacturing process of a corrugated honeycomb composite body for engineering. Background technique [0002] Corrugated honeycomb material is suitable for making products such as pallets with high flat compression strength due to its convenient production, high density and small honeycomb aperture. It is also a good sound-absorbing material. [0003] The prior art Chinese Patent Publication Nos. 2558510, 1322622, 1392045 disclose the manufacturing process and equipment of corrugated honeycomb composite paperboard. The basic method is to make single-sided corrugated, and then cut into strips by gluing and slitting to send to the traction vertical strip device. Then it is combined and assembled into a board core through a pressing device, and then dried and sent to the side gluing device for single-sided glue and then sent to the cutting device for simultaneous cutting. The strip-shaped board core is assembled on the splicing dev...
