Abstract
The invention relates to the technical field of building materials, in particular to a material for manufacturing a modified phenolic fireproofing insulation board and a preparation method thereof. The material for manufacturing the modified phenolic fireproofing insulation board comprises the following components in part by weight: 100 parts of modified phenolic resin, 2 to 4 parts of surfactant, 5 to 7 parts of foaming agent and 8 to 10 parts of curing agent. Due to the adoption of the technical scheme, the free phenol of the material is 0.09 percent, the free formaldehyde is less than 0.1 percent, the release amount of the formaldehyde is reduced obviously, and the physical and chemical properties of the material have no obvious difference compared with those of phenolic foam prepared under the normal condition, so the material can be applied to interior wall construction (interior wall heat-insulating systems) of buildings.
Description
Technical field
The present invention relates to building material technical field, especially relate to a kind of material for preparing 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 heat insulating inner wall 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 the prior art phenol formaldehyde foam is to add tensio-active agent by resol, whipping agent, and multiple processing aid such as solidifying agent is through stirring foaming, the foam that slaking forms.Yet the content of free phenol and free aldehyde is higher in the resol, and toxicity is big, harm environment and HUMAN HEALTH.Product colour is dark, influences outward appearance.How to reduce that the content of formaldehyde becomes an important problem in the phenol formaldehyde foam.
Summary of the invention
Technical problem to be solved by this invention is the defective that exists at prior art, provides a kind of and can enhance product performance, and can reduce the material of the preparation modified phenolic fireproof insulating plate of formaldehyde content.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: modified phenolic resins 100, 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: described tensio-active agent is silicone oil H230 or DC-193; Described whipping agent is Skellysolve A or carbonic acid gas; Described solidifying agent is xylene monosulfonic acid, tosic acid, phosphoric acid or sulfuric acid.All components among the present invention all at home market buy.The preparation method of the modified phenolic resins among the present invention is: with phenol and formaldehyde amount of substance ratio is 1: under the 1.5-3 condition, the sodium hydroxide of Dropwise 5 0% (with the mass ratio of phenol be 6-8: 100), then at 70～90 ℃ of reaction 150～180min, is 1-3 with urea and phenol by mass ratio: 100 add gradually, reaction 20min is cooled to room temperature, neutralizes with hydrochloric acid, the pH value that makes reaction soln is about 7, underpressure distillation cooling discharging during to required viscosity." modified phenolic resins " reaction mechanism among the present invention is to utilize urea and formaldehyde reaction to generate an Oxymethurea and dimethylolpropionic urea, generates urea-formaldehyde resin then, has consumed formaldehyde.In addition, reaction in the later stage resol a hydroxymethyl phenol and many hydroxymethyl phenols also can with remaining phenol reactant, but added after the urea, such reaction probability has reduced.Ultimate name of product 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: crosslinking reaction can take place in modified phenolic resins at a certain temperature, forms the needed crosslinking structure of phenol formaldehyde foam; Tensio-active agent plays a part modified phenolic resins in foaming system and whipping agent mixes; Whipping agent can make phenol formaldehyde foam produce microvoid structure; Solidifying agent is the crosslinked initiator of modified phenolic resins still not, 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, and its free phenol is 0.09%, and free aldehyde has obviously reduced the burst size of formaldehyde less than 0.1%, makes the present invention can be applied in the interior wall construction (heat insulating inner wall system) of buildings.
