Abstract
The invention relates to the technical field of building materials, in particular to a material for manufacturing a modified phenolic fireproof insulating plate. The material for manufacturing the modified phenolic fireproof insulating plate comprises the following components in part by weight: 100 parts of expandable phenolic resin, 2 to 20 parts of polyurethane prepolymer, 2 to 4 parts of surfactant, 5 to 7 parts of foaming agent and 8 to 10 parts of curing agent. The material improves the closed porosity of the phenolic fireproof insulating plate, reduces the hygroscopicity, quickens the speed of curing and molding reaction, also improves the intensity and roughness of the phenolic fireproof insulating plate, reduces the crispness of phenolic foam, and meets the requirements on outer wall construction (an outer wall insulation system) of buildings.
Description
Technical field
The present invention relates to building material technical field, relate in particular to a kind of material of making modified phenolic fireproof insulating plate.
Background technology
Because building energy consumption is higher, energy dissipation seriously is a kind of very general problem, so building energy conservation is direct, a cheap systems engineering alleviating energy scarcity.Owing to inflammable, shortcomings such as toxic smoke big, water absorbing properties difference, there is potential safety hazard as extruded sheet, styrofoam etc. in present employed building thermal insulation material.Phenol formaldehyde foam can be good at being applied in the exterior wall heat-preserving system, so is subjected to the people's attention just day by day owing to have that raw material is easy to get, cheap, characteristics such as product performance are good, difficult fire, put out certainly, low smog, water-proof breathable properties are good.But a shortcoming of prior art phenol formaldehyde foam be crisp, tensile strength is not high.Resol is carried out modification, and the fragility that overcomes phenol formaldehyde foam has become an important problem.
Summary of the invention
Technical problem to be solved by this invention is the defective that exists at prior art, and a kind of material that improves tensile strength, overcomes brittle manufacturing modified phenolic fireproof insulating plate is provided.The technical scheme that the present invention solves its technical problem employing is: a kind of material of making modified phenolic fireproof insulating plate, its component and parts by weight are: can send out resol 100, base polyurethane prepolymer for use as 2～20, tensio-active agent 2～4, whipping agent 5～7, solidifying agent 8～10.Technical problem to be solved by this invention also can further be solved by following technical solution: tensio-active agent is silicone oil H230 or DC-193; Whipping agent is Skellysolve A or carbonic acid gas; Solidifying agent is xylene monosulfonic acid, tosic acid, phosphoric acid or sulfuric acid.All components among the present invention all at home market make after buying or buying.The preparation method of the base polyurethane prepolymer for use as among the present invention is as follows: add in the exsiccant 250mL three-necked bottle by the mixture with 1mol polyethers and 1-3mol vulcabond, start stirring, be warmed up to 80 ℃ rapidly, and maintain the temperature at 80～90 ℃, reaction 3～4h.The resol sent out preparation method among the present invention is as follows: by 1mol phenol and the adding of 1.7-2.0mol formaldehyde are equipped with agitator, in the there-necked flask of thermometer and reflux condensing tube, open reflux, and begin to stir, when question response liquid is 40 ℃, the NaOH aqueous solution with 40% is regulated between pH value to 8～9, heats up and is controlled between 80 ℃～90 ℃ and react 90min; With acid for adjusting pH value to 6.8～7.2, be between 1.5700～1.5800 at 70 ℃ of following decompression dehydrations to its refractive index then; Be cooled to room temperature.Polyurethane-modified reactive modified phenolic resin mechanism among the present invention is: 1. the hydroxyl of the polyol in isocyanate groups and the component carries out crosslinked or chain extending reaction; 2. the methylol in isocyanate groups and the Ke Fa resol carries out crosslinking reaction.The result of two kinds of reactions has introduced the snappiness segment in phenolic aldehyde stiff molecule structure, fundamentally changed the stiff molecule structure that can send out resol, thereby has improved the toughness of phenol formaldehyde foam (goods), has reduced fragility; Introduce the characteristic of urethane simultaneously, as improved rate of closed hole, reduced water-absorbent, accelerated the curing molding speed of response, also improved the intensity and the toughness of the phenolic fireproof insulating plate of making of the present invention.Ultimate title of the present invention is called " phenol formaldehyde foam " in the present technique field.Each component of the present invention effect in the present invention is respectively: can send out resol crosslinking reaction can take place at a certain temperature, form the needed crosslinking structure of phenol formaldehyde foam; Tensio-active agent plays a part to send out resol in foaming system and whipping agent mixes; Whipping agent can make phenol formaldehyde foam produce microvoid structure; Solidifying agent still can not sent out the crosslinked initiator of resol, and can also promote the whipping agent foaming because of the heat release of initiation reaction.Preparation method of the present invention evenly stirs.The present invention is owing to adopt technique scheme, improved the rate of closed hole of phenolic fireproof insulating plate, reduced water-absorbent, accelerated the curing molding speed of response, the intensity and the toughness of phenolic fireproof insulating plate have also been improved, reduce the fragility of phenol formaldehyde foam simultaneously, satisfied the needs of skin construction (exterior wall heat-preserving system).
