Abstract
The invention discloses a phenolic foam plastic and a preparation method thereof, and belongs to the technical field of materials. The foam plastic is composed of the following raw materials in parts by weight: 60 to 80 parts of phenolic resin, 5 to 10 parts of polyethylene glycol, 3 to 6 parts of di-tert-butyl peroxide, 2 to 5 parts of alkylphenol polyoxyethylene, 4 to 10 parts of carbon black, 2 to 6 parts of nano zirconia, and 5 to 10 parts of sodium bicarbonate. The preparation method comprises the following steps: (1) weighing; (2) putting the raw materials into an injection moulding machine; (3) cooling and moulding. The raw materials are strictly selected, the parameters are precisely controlled, thus the prepared phenolic foam plastic preserves the excellent properties of phenolic resin and has an improved anti-compression performance at the same time, and moreover, the foam plastic has certain toughness and avoids the breaking.
Description
Technical field
The invention belongs to field of material technology, particularly a kind of phenolic foamed plastics and preparation method thereof.
Background technology
Phenolic foamed plastics is the class novel foamed plastic grown up in recent years,, be fuming amount low and high temperature stable performance good with its flame resistivity, adiabatic heat insulation, sound insulation, easy-formation processing and weather resistance and rank the prostatitis of all porous plastics preferably, be called as the emerging lagging material of the third generation.
Phenolic foamed plastics investigation and application abroad relatively early.Before nineteen forty-two, phenolic foamed plastics is made in laboratory, and starts to be applied at the World War II initial stage.So far, its matrix material is used in a large number the strict body of wall of the fire protection requirements such as aircraft, boats and ships, vehicle, tunnel, oil well, mine, sheet material, parts etc. abroad, now just turns to residential construction area.
Industry experts is thought, phenolic foamed plastics will fully develop talents in fields such as central air conditioner system, light thermal-insulation color steel, house lagging material, petrochemical pipes.Central air conditioner system lagging material be it is predicted, China's cities and towns new building area is per year over 400000000 square metres, and central air conditioner system lagging material needs estimate reaches 320 cubic metres.At present.Lagging material is applied to central air conditioner system in large quantities of country and local priority project, has saved mass energy, compensate for the deficiency of the aspects such as Conventional insulation weather resistance, environmental protection and fire prevention simultaneously.
But resol also still exists some problems at present: one is, fragility is large, and frangible, phenolic foamed plastics is very fragile, particularly when density is low; Two is be corrosive, and acid residual in foam has corrosive nature to metallic substance.
Summary of the invention
The technical problem that the present invention solves: for above-mentioned deficiency, overcome the defect of prior art, the object of this invention is to provide a kind of phenolic foamed plastics and preparation method thereof.
Technical scheme of the present invention: a kind of phenolic foamed plastics, is prepared from by the raw material of following parts by weight:
Resol 60-80 part, polyoxyethylene glycol 5-10 part, di-t-butyl peroxide 3-6 part, alkylphenol polyoxyethylene 2-5 part, carbon black 4-10 part, nano zircite 2-6 part and sodium bicarbonate 5-10 part.
As preferably, described porous plastics is prepared from by each component of following mass fraction: resol 65-78 part, polyoxyethylene glycol 6-9 part, di-t-butyl peroxide 4-5 part, alkylphenol polyoxyethylene 3-4 part, carbon black 6-8 part, nano zircite 3-5 part and sodium bicarbonate 6-9 part.
As preferably, described porous plastics is prepared from by each component of following mass fraction: 76 parts, resol, polyoxyethylene glycol 8 parts, di-t-butyl peroxide 5 parts, alkylphenol polyoxyethylene 3 parts, carbon black 7 parts, nano zircite 4 parts and sodium bicarbonate 8 parts.
A preparation method for phenolic foamed plastics, preparation process is as follows:
(1) each raw material is accurately taken;
(2) put into injection moulding machine after being mixed by raw material shaping, barrel temperature 45 DEG C-75 DEG C, injection pressure 122-175Mpa, die temperature 155 DEG C-185 DEG C, dwell time 45-75s, cooling time 45-100s;
(3) after injection moulding machine cooling forming, namely phenolic foamed plastics is obtained.
As preferably, in step (2), injection pressure is 165Mpa, dwell time 50s.
Beneficial effect: phenolic foamed plastics provided by the invention, is different from the phenolic foamed plastics that traditional mechanical process or Physical prepare, but adopts injector integral forming method to prepare.Phenol formaldehyde foam is one-body molded, and the requirement for technique is comparatively strict, but more simple and easy relative to additive method, also cost-saving, therefore, the present invention, strictly chooses raw material, precise controlling parameter, makes the phenol formaldehyde foam that the present invention improves, and maintains the excellent performance of resol on the one hand; On the other hand, improve the compressive property of resol, make it have certain toughness, avoid fragmentation.
