Abstract
The utility model discloses an anti-cracking steel fiber reinforced phenolic resin foam insulation board. Steel fibers, the surfaces of which are provided with epoxy resin adhesive coatings in a solidified manner, are uniformly distributed in a phenolic resin foam insulation board, wherein the epoxy resin adhesive coatings are respectively 0.05mm to 0.1mm thick, and the steel fibers are respectively 10mm to 50mm long and 0.1mm to 0.5mm in diameter. A layer of epoxy resin adhesives, which are coated on the surfaces of the steel fibers, have good adhesion with the steel fibers and can be tightly bonded with phenolic resin foams, so that the steel fibers and the phenolic resin foams are firmly bonded and are unlikely to shed. Thus, the anti-cracking performance of the phenolic resin foams is improved and the service life of the phenolic resin foams is prolonged.
Description
Technical field
The utility model relates to warming plate, especially the phenolic resin foam warming plate.
Background technology
That phenolic aldehyde foam thermal insulation material has is high from heavy and light, specific strength, process that the advantages such as easy, especially its coefficient of thermal conductivity are little, good flame resistance, the rate of being fuming are low, is widely used in the fields such as civil construction, petrochemical industry and Aero-Space.Phenolic hydroxyl group and the easy oxidation of methylene owing to containing in phenolic resins on a large amount of rigidity benzene ring structure, particularly phenyl ring, cause the phenol formaldehyde foam poor toughness, and matter is crisp, easily fall slag, and these shortcomings are restricting its application in real engineering.Therefore, people are actively finding the method for phenolic resin foam modification always.
Because steel fibre has very high modulus of elasticity, there is Introduction of Literatures to add the intensity that steel fibre improves phenol formaldehyde foam in phenol formaldehyde foam.But because steel fiber surface is smooth, and phenol formaldehyde foam and steel fiber surface adhesion a little less than, easily delamination, so the phenolic resin foam warming plate of this landfill steel fibre in practice can't large scale application.
The utility model content
In order to overcome the technological deficiency of existing phenolic resin foam warming plate poor toughness, easy embrittlement, the utility model provides a kind of anti-cracking steel fibre to strengthen the phenolic resin foam warming plate.
For achieving the above object, the structure that the anti-cracking of the utility model steel fibre strengthens the phenolic resin foam warming plate is: it comprises the phenolic resin foam warming plate, it is characterized in that, being evenly distributed with surface cure in the phenolic resin foam warming plate has the steel fibre of epoxy resin adhesive coating, the thickness of epoxy resin adhesive coating is 0.05-0.1mm, the length of steel fibre is 10-50mm, and diameter is 0.1-0.5mm.
Preparation method of the present utility model is:
The first step is: steel fibre is carried out to surfacing, and processing method is: apply one deck epoxy resin adhesive at steel fiber surface, the thickness of coating is 0.05-0.1mm, and epoxy resin adhesive is sticked on steel fibre, and solidifies.
Second step: by Foaming of phenolic resin.
Steel fibre after surfacing is evenly mixed together with the raw materials such as expandable phenolic resin, blowing agent, curing compound and stabilizing agent, join in mould and foamed, can make anti-cracking steel fibre after solidifying fully and strengthen phenolic foam heat insulation plate.
Described phenolic resins is expandability thermosetting phenolic resin commonly used.
Described blowing agent can be one or more mixtures in pentane, isopentane, pentamethylene.
Described curing compound can be one or more the sour mixtures in hydrochloric acid, phosphoric acid, acetic acid, benzene sulfonic acid.
Described stabilizing agent is Tween-80.
Above-mentioned steel fibre, epoxy resin adhesive raw material, Foaming of phenolic resin raw material are commercially available this area conventional material, and the raw-material proportioning of Foaming of phenolic resin and technique are undertaken by production technology commonly used in existing document.
Good effect of the present utility model is: at steel fiber surface, apply one deck epoxy resin adhesive, this layer of epoxy resin has adhesiveness preferably to steel fibre, and with phenol formaldehyde foam also can be in conjunction with closely, make steel fibre and phenol formaldehyde foam bonding firmly, be difficult for delamination, improve the crack resistance of phenol formaldehyde foam, extended the application life of phenol formaldehyde foam.
Because steel fiber surface is smooth, and phenol formaldehyde foam and steel fiber surface adhesion a little less than, if directly by the steel fibre landfill in phenol formaldehyde foam, the interface binding intensity that steel fibre is combined with phenol formaldehyde foam a little less than, easily delamination.
The accompanying drawing explanation
Fig. 1 is generalized section of the present utility model;
Fig. 2 is A section enlarged drawing in figure.
In figure, 1-phenolic resin foam warming plate, 2-steel fibre, 3-epoxy resin adhesive coating.
Below further illustrate with reference to the accompanying drawings structure of the present utility model
The specific embodiment
As can be seen from Figure 1, the structure of the utility model warming plate is: be evenly distributed with steel fibre 2 in phenolic resin foam warming plate 1, from Fig. 2 enlarged drawing, can find out, at steel fibre 2 surface cures, epoxy resin adhesive coating 3 is arranged, requiring the thickness of epoxy resin adhesive coating 3 is 0.05-0.1mm, the length of steel fibre 2 is 10-50mm, and diameter is 0.1-0.5mm.
During enforcement, first on steel fibre 2 surfaces, apply one deck epoxy resin adhesive coatings 3, after drying, but it is mixed with materials such as hair style phenolic resins, blowing agent, curing compound, stabilizing agents, be placed in mould and foam and get final product.
