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 bu...

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...
