Abstract
The invention discloses an A-grade flame retardant modified polystyrene board and a preparation method thereof. The polystyrene board comprises 20-25 parts by weight of flame retardant polystyrene resin, 0.4-0.5 part by weight of foaming agent, 40-50 parts by weight of talcum powder, 6-10 parts by weight of aluminium hydroxide, 2-4 parts by weight of surfactant and 3-5 parts by weight of curing agent. The invention also discloses a corresponding preparation method. The modified polystyrene board has the effects of increasing the burning grades of the traditional polystyrene boards to grade A2 (excellent fireproof performance), simultaneously maintaining various original advantages of the traditional polystyrene boards and achieving the perfect performances of insulating and fireproofing and is totally different from EPS (expanded polystyrene) boards achieving the aim of flame retardance by adding organic flame retardants on the market. In fireproof experiments carried out by state authorities, the results of burning experiments show that the ablation phenomenon exists within the range of 1 meter at the bottom and other parts are intact and are free from molten drops or collapse.
Description
Technical field
What the present invention relates to is a kind of flame retardant type material of construction, in particular flame-retardant modified styrofoam of a kind of A level and preparation method thereof.
Background technology
Traditional E PS expansion polyphenyl plate belongs to inflammable material, though add organic fire-retardant can improve its flame retardant resistance, along with the volatilization of organic fire-retardant, EPS expansion polyphenyl plate flame retardant properties is also along with decline, and its flame retardant properties can only reach the B1 level after testing; In addition, traditional E PS expansion polyphenyl plate belongs to thermoplastic material, meeting attacks with fire hits post shrinkage, fusing, trickling, be accompanied by strong smog in fire process, not only serious environment pollution, and fire spread speed is fast, burnt area is large, be difficult to put out a fire to save life and property, often cause great loss of life and personal injury, CCTV's big fire, the teacher apartment big fire of Jiangzhou road, Shanghai, prosperous fire of Shenyang feudal dynasty ten thousand are exactly lesson written in blood.The fire disaster risen one after another, cause national high-level leader's close attention.On March 15th, 2011, no matter issued No. 65 files of " notice of protecting material fire supervision management relevant requirements about further clear and definite covil construction outward " by the Fire-Fighting Bureau under the Ministry of Public Security, be that the combustionproperty of house, Gongjian, reconstruction of existing building lagging material used must reach the A level.Since No. 65 file distribution, on China's insulation market, a large amount of inorganic materials goes up wall one after another, although solved the fp problem, caused larger problem: building energy conservation is not up to standard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, flame-retardant modified styrofoam of a kind of A level and preparation method thereof is provided, improve its fire savety, guarantee heat insulating effect simultaneously.
The present invention is achieved by the following technical solutions, the flame-retardant modified styrofoam of A level of the present invention, by weight, comprise 20～25 parts of flame-retardant polystyrene resins, 0.4～0.5 part of whipping agent, 40～50 parts of talcum powder, 6～10 parts, aluminium hydroxide, 2～4 parts, tensio-active agent, 3～5 parts, solidifying agent.
The preparation method of the flame-retardant modified styrofoam of a kind of A level comprises the following steps:
(1) by flame-retardant polystyrene resin and whipping agent, under 102～110 ℃ of the vapor pressures of 0.3～1.0bar through the expanded foamed flame-retardant polystyrene foam grain that makes;
(2) will mix in the flame-retardant polystyrene foam grain through surfactant-modified fire prevention coating material, then add solidifying agent, stir 15～20 minutes at 60～80 ℃ of temperature, form the xln of surface uniform parcel fire-retardant material;
(3) finally by above-mentioned xln injection plate forming machine, under the saturated vapor effect of 100 ℃, merge moulding.
Fire prevention coating material in described step (2) is to take 325～425 purpose talcum powder as basis, adds 15～20% nano level aluminium hydroxide and 0.5～0.8% tensio-active agent to mix and forms, by weight.
As one of optimal way of the present invention, described solidifying agent is lithium base solidifying agent.
Through the polymerization curing reaction between flame-retardant polystyrene foam grain and fire prevention coating material, be wrapped in the exotic materials xln with fire resistance around making the flame-retardant polystyrene foam grain, form good inflaming retarding shell, isolated air, effectively stop flame transmission, and will isolate between particle and particle, realized interior fire protection minute storehouse, thereby thoroughly changed traditional styrofoam and met fire contraction, the defect of molten drop.Through with fire prevention coating material polymerization after, though the unit weight of material has increase, very little on its thermal conductivity impact; and the fire prevention coating material is without degraded; a flame-retardant polystyrene foam material is had to provide protection, and when this has just determined life-time service, heat insulating effect can not reduce.
Styrofoam after modification, brought up to the burning grade of traditional styrofoam the A of fire resistance excellence
2level has retained the original plurality of advantages of traditional styrofoam simultaneously, has realized being incubated and the perfect performance of fp, is different from fully on market the EPS plate is realized to fire-retardant purpose by the mode that adds organic fire retardant.In the fire prevention experiment of national authority department, the result of combustion experiment is: 1 meter of bottom scope has an ablation phenomen with interior, and all the other positions remain intact, and there is no the molten drop thing, subside.
The flame-retardant modified styrofoam of A level is applied widely, can be used for following occasion:
1, the thin plastoring system of the inside and outside wall thermal insulation of all kinds of buildings;
2, the base material of exterior wall integrated decorative insulation board material;
3, steel structural plant roof, body of wall, freezing, metallic glass curtain wall heat insulation board special;
4, central air-conditioning ventilation sheet material sandwich material;
5, building roof heat-insulation system heat preservation plate material;
6, antitheft door, fire door sandwich sheet;
7, the insulating board of automobile, train, boats and ships.
The present invention has the following advantages compared to existing technology:
1, A level fire prevention
The structure-type fire resistance property that uses the microfacies compounding technology to form the fire prevention barrier film is that continue, permanent; When the flame-retardant modified styrofoam of A level is met fire, do not shrink, not molten drop, do not burn, do not smolder, do not penetrated by flame, thoroughly changed the fire resistance of traditional E PS plate, be different from fully by adding a large amount of organic fire-retardants to improve the styrofoam of flame retardant resistance;
2, energy-efficient
Thermal conductivity slightly increases, but still in 0.041, and life-time service can not affect heat insulating effect; And the thermal conductivity of mineral-type lagging material itself surpasses 0.060, practical application effect is poor, and, after As time goes on making moist or absorbing water, heat insulating effect can obviously descend;
3, heat-insulation system maturation
The flame-retardant modified styrofoam of A level has been acted on the stable good characteristic of traditional styrofoam wood property, has the security of life-time service, easy and simple to handle, loss is low;
4, reasonable price
With the mineral-type lagging material, compare, low price, because the flame-retardant modified styrofoam of A level is relatively thin, do not need extra reinforcement anchoring yet; With heat cured phenolic board, with polyurethane sheet, compare, material cost is lower, and the organic materials of consumption only has their 1/3.
