Abstract

The invention discloses a kind of novel flat-plate solar thermal collector phenolic aldehyde foam thermal insulation material, described insulation material is prepared by phenolic resin, inorganic combustion inhibitor, foaming agent, firming agent, stabilizer, toughener and stalk fibre mixed foaming by weight, solidification.Phenol formaldehyde foam inorganic heat insulation material of the present invention is applied in solar water heater, the contraction of polyurethane foam existence can be efficiently solved, squeeze the problems such as flat inner bag, the stalk fibre added can improve the heat conductivility of phenol formaldehyde foam, heat insulation effect improves further, and this phenol formaldehyde foam fire protection flame retarding, operating temperature range width, energy-conserving and environment-protective.

Description

A kind of novel flat-plate solar thermal collector phenolic aldehyde foam thermal insulation material
Technical field
The present invention relates to insulation material technical field, be specifically related to a kind of novel flat-plate solar thermal collector phenol formaldehyde foam and protect Adiabator.
Background technology
Flat-plate solar collector is typically by heat-absorbing plate core, housing, transparent cover plate, insulation material and relevant parts group Become.At adjunction circulating line, after attemperater, solar radiant heat can be absorbed, make water temperature raise.For flat-plate solar collector The material of thermal insulation layer mainly has rock wool, glass cotton, polyurethane, a polystyrene etc., but at present, and using more is rock wool and glass Cotton.But owing to glass cotton or this kind of material of rock wool have heat conduction system
The shortcomings such as number height, the material internal compactness moisture absorption poor, easy, poor toughness so that the entirety of flat-plate solar collector Insulating efficiency is low, and service life is shorter.
Phenol formaldehyde foam is a kind of novel thermal insulation material that can improve flat-plate solar collector.Phenol formaldehyde foam material That expects has the thermal and insulating performance that (1) is outstanding, heat conductivity < 0.03W/m K.(2) higher operating temperature.Phenol formaldehyde foam Can be at-200 DEG C ~ 160 DEG C (allowing instantaneous 250 DEG C) long-term works, ungauged regions.(3) outstanding weatherability.It is chronically exposed to high temperature Under, still there is preferable thermal and insulating performance, any volatile material that may intercept solar radiation will not be discharged.(4) Noninflammability.Phenol formaldehyde foam (100mm is thick) fire-resistance flame ability was not pierced up to more than 1 hour, and smokelessly, dissipated without harmful gas Send out.When phenol formaldehyde foam is shown in naked light, surface forms structural carbon, and thing, nothing curling, nothing melt phenomenon without dripping off.After overdoing, surface is formed The graphite linings of structural carbon, is effectively protected the inner structure of foam.(5) environmental protection.Use floride-free foaming technique, without fiber, meet National, international environmental requirement.Phenol formaldehyde foam is close with the heat-insulating property of polyurethane, but has higher work temperature than polyurethane Degree, and there is flame-retarding characteristic.Phenol formaldehyde foam is compared with rock wool simultaneously, has more preferable heat-insulating property, the most harmless.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of novel flat-plate solar thermal collector phenol formaldehyde foam Insulation material.
Realizing the object of the invention technical scheme is:
A kind of novel flat-plate solar thermal collector phenolic aldehyde foam thermal insulation material, by the raw material mixed foaming of following weight portion, admittedly Change and prepare:
Phenolic resin 80-95 part
Inorganic combustion inhibitor 5-8 part
Foaming agent 8-15 part
Firming agent 6-10 part
Stabilizer 2-5 part
Stalk fibre 8-10 part
Described inorganic combustion inhibitor is one or both the mixing in aluminium hydroxide, MAP or antimony oxide.
When the mixture that described inorganic combustion inhibitor is aluminium hydroxide and MAP, described aluminium hydroxide and MAP Mass parts than for 60-80:5-10；When the mixture that described inorganic combustion inhibitor is aluminium hydroxide and antimony oxide, hydrogen-oxygen Change the mass parts of aluminum and antimony oxide ratio for 60-80:3-7.
Described foaming agent is one or more in pentane, hexane or their isomers.
Described firming agent is phosphoric acid and/or benzenesulfonic acid.
Stabilizer is not particularly limited, generally type siloxane foam stabiliser, it is desirable to foam cell can be made careful all Even and give the preferable rate of closed hole of foam.The present invention uses polyoxyethylene grafting or block type aqueous dimethylformamide silicone oil as stabilizer.
Described stalk fibre is in corn stalk fiber, Caulis Sacchari sinensis stalk fibre, rice straw fiber or producing fibre from cotton stalk One or more.
Stalk fibre has higher specific strength, the ratio performance such as elastic modelling quantity, compliance, can be effective as reinforcing material Ground improves the performance of phenol formaldehyde foam, and stalk fibre has abundant raw material and a low-cost feature, and enhanced phenol The advantages such as aldehyde foam is prone to degraded and reclaims, environmentally safe.
Advantages of the present invention is: phenolic aldehyde foam thermal insulation material of the present invention is applied in solar water heater, can be effectively Solving the contraction of polyurethane foam existence, squeeze the problems such as flat inner bag, the stalk fibre of addition can improve the heat conductivity of phenol formaldehyde foam Can, heat insulation effect improves further, and this phenol formaldehyde foam fire protection flame retarding, operating temperature range width, energy-conserving and environment-protective.
