Problems solved by technology

After being impregnated with flame-retardant and fire-resistant materials such as amino resin, phenolic resin, melamine resin, sodium silicate, etc., it is difficult for ordinary paper to impregnate the inner fibers, and it is usually wrapped on the outside. When it is burned in a fire, it has a certain flame-retardant However, the internal fibers will emit a large amount of carbon monoxide and jet flames, which will cause great harm to the environment
[0004] Generally, the high-strength corrugated cardboard (multi-layer) used for packaging cannot meet the needs of engineering materials in terms of mechanical strength and moisture resistance perpendicular to the surface of corrugated cardboard.

Embodiment 1

[0032] Embodiment 1: the production process is:

[0033] Single-sided corrugated cardboard → first impregnation with flame retardant and antifungal agent → drying in drying oven → second impregnation with fireproof adhesive coating → drying oven → glue coating → cutting to length → composite drying → composite honeycomb filling with inorganic materials → phenolic resin Foam sealing → finished product

[0034] The water-based flame retardant antifungal agent consists of 3-8% of zinc borate, 5-8% of sodium tetraborate, 3-5% of disodium hydrogen phosphate and the rest of water according to weight percentage.

[0035]The fireproof adhesive is composed of 80-90% sodium silicate with a Baume degree of 35-60°C, 5-15% sodium fluorosilicate, 2-5% polyvinyl alcohol and 1-1.5% sodium stearate in terms of weight percentage .

[0036] The composite honeycomb is filled with microbead glass, the thickness of the composite is 6cm, and the performance test of the composite wallboard covered ...

Embodiment 2

[0045] The water-based flame retardant antifungal agent is composed of 5-8% of ammonium sulfate, 5-6% of sodium tetraborate, 4-5% of ammonium molybdate and the balance of water according to weight percentage.

[0046] The fireproof adhesive is composed of 80-90% of sodium silicate with a Baume degree of 35-60°C, 5-15% of starch derivatives, 1-1.5% of sodium stearate and 3-5% of ethylene glycol in terms of weight percentage.

[0047] Production process: Use 1650 type single-sided corrugated production equipment, corrugated mold 3.0mm, corrugated height 5.0mm A-type corrugated. Use flat backing paper as C-grade containerboard with a width of 1600 mm and a gram weight of 175 grams, 150 g of ordinary corrugated paper as the corrugated layer, and polyvinyl alcohol as an adhesive to obtain a single-sided corrugated board. Cut length × width = 4000 × 1600 (mm). After spraying or dip-coating single-sided corrugated cardboard with water-based flame-retardant and anti-fungal agent, aft...

Embodiment 3

[0049] Single-sided corrugated cardboard produced by single-sided corrugating machine → dip coating, dip tank water-based flame retardant and antifungal agent → drying oven dehydration → secondary coating dip coating or spraying fireproof gel sodium silicate → secondary drying oven dehydration → Corrugated gluing again, cutting→collecting and compounding→rolling off the line→drying and curing products.

[0050] The water-based flame retardant antifungal agent consists of 3-6% of ammonium chloride, 4-5% of ammonium molybdate, 4-8% of ammonium polyphosphate, 2-3% of calcium propionate and the rest of water according to weight percentage.

[0051] The fireproof adhesive is composed of 85-98% of sodium silicate, 1-14% of glycerol and 1-1.5% of sodium stearate in terms of weight percentage.

[0052] Utilize the wooden fireproof door that the product of the present invention makes to measure its thickness to be 50mm main technical index: fire resistance limit ≥ 1.2h, composite mater...

Abstract

The present invention relates to a production process of fire-proof high-strength heat-insulating corrugated sheet honeycomb composite material. Said production process includes the following steps: (1), impregnating single corrugated sheet with water base flame-retardant or water base flame-retardant anti-mildew agent or spray-coating said single corrugated sheet with said water base flame-retardant or water base flame-retardant anti-mildew agent; (2), then utilizing impregnation method or spray-coating process to cover said single corrugated sheet with fire-resisting adhesive; and (3), making the above-mentioned obtained corrugated sheets be successively superimposed together so as to obtain the invented product.

Description

technical field [0001] The invention belongs to a multi-layer composite body of corrugated cardboard, and in particular relates to a fire prevention enhancement treatment process of corrugated cardboard composite board. Background technique [0002] Due to its good mechanical structure properties, energy-saving, light-weight, and environmental-friendly advantages, paper-based honeycomb materials are widely used in the sandwich filling of packaging plate structures, and have also been well promoted in the fields of building materials, furniture, vehicles and ships, etc. application. [0003] Regardless of whether it is a hexagonal honeycomb or a corrugated cross-section honeycomb, their heat and sound insulation performance is mainly produced by laying on the board. The middle of the honeycomb core material is transparent and is an air medium. Paper honeycomb materials can achieve flame retardant effects by soaking and spraying flame retardants, or use pretreated flame reta...
