Abstract
The invention discloses a modified EPS flame-retarding heat insulating plate. The EPS heat insulating plate prepared by taking resin A as an adhesive, taking polystyrene foamed particles as a foamed heat insulating material and taking aluminum phosphate as flame-retarding filler is excellent in heat insulation property and also excellent in flame resistance, reaches grade A in combustion grade, and is free of shrinkage, collapse and dripping when grilled by flames; the modified melamino-formaldehyde resin-based EPS flame-retarding heat insulting plate disclosed by the invention is good in mechanical property, low in water absorptivity, simple and easy to implement in preparation method, relatively low in cost and suitable for popularization and application.
Description
Technical field
The present invention relates to a kind of EPS fire-retardant heat insulation plate, belong to material of construction manufacturing technology field.
Background technology
Organic insulation material at present for external wall Surgery therapy mainly contains molded polystyrene foams plastic plate (EPS), extruded polystyrene foam board (XPS), hard polyurethane foam plate (PU), phenolic foam board (PF) etc.Wherein the use in External Thermal Insulation System of polystyrene foam, extruded polystyrene foam is the most extensive, but EPS and XPS is inflammable material, the fire in a lot of building is exactly because the use of inflammable Surgery therapy macromolecular material causes flame rapid spread to other floor, cause fire uncontrollable, and smog and the toxic gas of burning release allow the people be in fire suffocate, and cause huge property damage and serious loss of life and personal injury.
The coated EPS composition board of mortar conventional in the market, although surperficial difficult combustion screed, high temperature scorch lower inside EPS plate can rapid contraction on melting, cause whole composition board to subside, break; Also have some flame retardant types EPS warming plate, its method is after preferred fire retardant and the melting of polystyrene phase, then it is molded to make granule foaming, for reaching the object of melting altogether, its fire retardant need select collocation meticulously, and is subject to larger limitation, flame retardant effect is undesirable, can only reach B1 level.So, need to carry out flame-retardant modified to this type of thermal insulation material.
Summary of the invention
The object of this invention is to provide a kind of modified EPS fire-retardant heat insulation plate, its combustionproperty reaches A level, meets naked light and does not burn, do not subside, without drippage; And there is good heat-insulating property and mechanical strength.
For achieving the above object, the technical solution used in the present invention is: a kind of modified EPS fire-retardant heat insulation plate, is prepared by the raw material of following mass parts:
100 parts, EPS particle
Resin A 80 parts
Aluminum phosphate 18 ~ 22 parts
Ammonium persulphate 4 ~ 6 parts
Described Resin A is prepared by the raw material of following mass fraction:
500 parts, formaldehyde
Benzoguanamine 200 parts
Epoxy resin 80 parts
Sodium bicarbonate 5 parts.
Preferably, described epoxy resin is bisphenol A type epoxy resin.
In technique scheme, the preparation of described Resin A comprises the steps: by proportioning, adds in container by formaldehyde, sodium bicarbonate; Then benzoguanamine is added, in 80 DEG C of stirring reactions 40 minutes; Add epoxy resin again, continue reaction 40 minutes; Then temperature is adjusted to 30 DEG C, reacts and obtain Resin A after 60 minutes.
In the present invention, the preparation of modified EPS fire-retardant heat insulation plate comprises the steps:
By proportioning, aluminum phosphate, ammonium persulphate, above-mentioned Resin A and EPS particle are injected in mould, through hot-forming, described modified EPS fire-retardant heat insulation plate can be obtained.Hot press forming technology for first temperature be 105 DEG C, pressure be 11KPa condition under solidification 25 minutes, then temperature be 80 DEG C, pressure be 5KPa condition under ageing 180 minutes.
Due to the employing of technique scheme, compared with prior art, tool of the present invention has the following advantages:
Being caking agent by adopting Resin A of the present invention, being foamed heat-insulating material with polystyrene foaming granule, be that the EPS warming plate prepared of fire-retardant filler is while having excellent heat-insulating property with aluminum phosphate, also there is excellent flame retardant properties, its burning grade reach A level, and by flame scorch do not shrink, nothing subside, without dropping; Modified melamine-formaldehyde resin base EPS fire-retardant heat insulation plate mechanical property of the present invention is good, water-intake rate is low, and preparation method is simple, and cost is lower, is suitable for applying.
