Embodiment 1

[0025] A binder used for foamed phenolic color steel composite materials, the specific formula of the binder for preparing 1000 grams is as follows:

[0026]

[0027]

[0028] making process:

[0029] Under low-speed stirring, add metered water-based polyurethane emulsion and ethylene-vinyl acetate water-based emulsion and stir evenly; under low-speed stirring, add metered propylene glycol ether, polyoxyethylene alkyl ether, sorbitan lauric acid triglyceride, and caprylic acid soap in turn. Stir well; under low speed stirring, add the metered ordinary silicate 42.5 cement and stir well.

[0030] This adhesive is suitable for the double-sided coating of foamed phenolic in the foamed phenolic / color steel composite material.

Abstract

The invention discloses a bonding agent for a foam phenolic aldehyde color steel composite material. The bonding agent is prepared from the following raw materials in percentage by weight: 20-60% of a water-based polyurethane emulsion, 10-40% of a blending modified emulsion, 1.5-10% of a functional filling material, 0.5-0.8% of a film-forming aid, 1.5-3.5% of a thickening agent, 0.02-1.2% of a penetrating agent, 0.5-1.5% of a defoaming agent, 0.015-0.1% of a drier and 0.05-1.5% of a mould-proof bactericide. The bonding agent disclosed by the invention is used for covering two surfaces of a foam phenolic aldehyde plate to form a protective film, so that bonding agent not only can effectively prevent powder falling and but also has certain toughness. The bonding agent disclosed by the invention has relatively low surface tension and good film-forming property; meanwhile, the bonding agent has relatively good penetrability which is beneficial for generating an 'anchor chain' immerged into the foam phenolic aldehyde plate. The bonding agent disclosed by the invention can realize effective bonding with metals and inorganic materials, and has high bonding strength.

Description

technical field [0001] The invention relates to a novel fire-proof and heat-insulating material, in particular to a binder used for a foamed phenolic color steel composite material. Background technique [0002] Foamed phenolic material is a foamed material generated under physical and chemical action with phenolic resin as the matrix. Foamed phenolic material is known as the "king of thermal insulation materials" for its excellent properties such as heat resistance, flame retardant, low smoke, flame penetration resistance, good thermal insulation, corrosion resistance, dimensional stability, and anti-aging. In recent years, due to the frequent major fire accidents in various places, more stringent requirements have been put forward for the flame retardancy and thermal stability of various foam materials. Foamed phenolic has received extensive attention for its excellent performance. [0003] The biggest defect of the foamed phenolic material is that it is easy to pulverize...
