Description
Technical field
The invention belongs to building exterior wall material technical field, be specifically related to a kind of red mud phenolic aldehyde foam thermal insulation material and system thereof
Preparation Method.
Background technology
Phenolic-aldehyde heat-insulation board and hard polyurethane foam belong to organic thermosetting thermal insulation material, building energy saving rate the most in recent years together
Gradually step up, application insulation material technical performance more and more higher, market demand is increasing.At Application in Building insulation material
In application, not only require that physical technique performance is high and it is necessary to reach fire protecting performance.The foam of phenolic resin production and polyurethane
Relatively good insulation material is belonged to though hard bubbling, but excellent, shortcoming that two class insulation materials are had nothing in common with each other, not there is fine complex art
Performance.The hard polyurethane foam of polyurethane resin synthesis, has the spy such as lightweight, high-strength, heat conductivity is low, good toughness and easy construction
Point, but fire protecting performance only up to reach B1 level fire protecting performance, oxygen index (OI) only up to reach 30%.
The phenolic-aldehyde heat-insulation board that phenolic resin produces, possesses the main principal advantages of Polyurethane Thermal Insulation Building Materials, but fire line
Can highlight than hard polyurethane foam, fire-resistant combustion penetrates, cigarette high temperature resistant, low, and oxygen index (OI) is up to 50%, but phenolic-aldehyde heat-insulation board and polyurethane
Hard bubbling and compare, the shortcoming of phenolic-aldehyde heat-insulation board maximum is that fragility is big, acid big.Owing to the fragility of phenolic-aldehyde heat-insulation board is big, phenolic aldehyde heat preserving
There is the problems such as dry linting, elasticity is low, compressive strength is low, and heat conductivity is the most up to standard in plate, intrinsic excellent fire protecting performance does not has in use
Can be utilized very well, therefore, affect the extension of this products application technology, bring a lot of inconvenience to transport, construction simultaneously.Especially
Pull strength is low, is difficult to meet relevant criterion requirement.Owing to acidity is big so that phenolic-aldehyde heat-insulation board connects with metal, cement-based material
Touch and have certain corrosivity.
Summary of the invention
In order to solve the problem that the heat conductivity of above phenolic foam board is higher, toughness is bad, the present invention proposes a kind of red
Mud phenolic aldehyde foam thermal insulation material, this insulation material not only intensity is high, and heat conductivity is low.
The technical scheme is that and be achieved in that:

Further, described coupling agent is Silane coupling agent KH550 or silane coupler KH560.
It is a further object to provide the preparation method of a kind of red mud phenolic aldehyde foam thermal insulation material, including following step
Rapid:
1) phenolic resin, polyurethane, firming agent and toughener are carried out under the conditions of 40～60 DEG C mix homogeneously, obtain
Mixture A；
2) by mixture A, red mud, coupling agent, surfactant and foaming agent mixing and stirring, it is quickly poured into preheating
Mould in foam, solidify.
Further, described step 2) the preheating temperature of preheated mold is 30～50 DEG C.
The method have the benefit that
1, its toughener of red mud phenolic aldehyde foam thermal insulation material of the present invention is nano silicon with graphite oxide at alkyd
The mixture formed in saline solution, toughening effect is notable, and has the most fire-retardant and heat resistance.40～60 DEG C of conditions
Under, phenolic resin, firming agent and toughener mix, beneficially the toughening modifying of phenolic resin.Owing to polyurethane is tough and tensile,
Soft and adhesion epistasis energy, participates in phenolic foam board Aided Modification so that phenolic foam board toughness improves, and is difficult to dry linting,
Elastic enhancing.Add red mud and can improve the performance of insulation material acid rain resistant.In red mud, existing silicate has again ferrum oxide, oxidation
The metal-oxides such as calcium, make the thermostability of phenolic foam, anti-flame performance improve.By the effect of coupling agent, red mud without
Machine filler is uniformly dispersed in phenolic resin, and hole is fine and smooth, dimensionally stable, and its resistance to compression, tension combination property improve, and save into
This.
