Abstract
The invention relates to a vermiculite composite thermal insulation material, which consists of main material A, main material B, auxiliary material A and auxiliary material B. The vermiculite composite thermal insulation material is characterized in that: the parts by weight of the main material A and the main material B are as follows: 1 to 8 parts of vermiculite as the main material A with the grain size of 30 to 100 meshes and 1 to 8 percent of phenolic resin as the main material B; the auxiliary material A is the mixture of talcum powder, foaming agent, activator, softening agent and curing agent mixed according to any proportion, and the part by weight of the auxiliary material A is 25 to 45 percent of the main material B; the auxiliary material B is short glass fibres, and the part by weight of the auxiliary material B is not higher than 10 percent of the main material B. The thermal insulation material can reach the highest burning level, i.e. level A, the manufacturing cost of the level A thermal insulation material is reduced, and various properties are good; the vermiculite composite thermal insulation material cannot be formed into building waste, scraps can be directly filled back into farmlands after being ground, and cannot harm farmlands, and the application range is wide.
Description
Technical field
The present invention relates to field of compound material, especially a kind of building thermal insulation material.
Background technology
At present the lagging material that extensively adopts of building trade has PES, PEF to gather to mould plate etc.; This type of lagging material is in production, use; Not only environment is brought outside the pollution; More seriously be easy firing, be prone to aging (national Specification work-ing life be 25 years, use to occur catabiosis in various degree after 6 years).Adopt PES, PEF to gather and mould plate; No matter common variety still is fire-retardant; A fire-retardant just conception of species of these materials; Their material molecular structure is exactly an incendiary chemical molecular structure very easily, also can produce a large amount of poisonous, obnoxious flavour during burning, bring great potential safety hazard and harm can for building and people's life.Simultaneously, the chemical constitution of this type material causes in the building life cycle, will carry out replacing, the maintenance of three thermal insulation layers at least, has wasted manpower, financial resources and natural resources in a large number.
Vermiculite is one of raw material of the making lagging material used always, but its water-intake rate is very high, is easy to draw the moisture in the environment; Influence its heat retaining property, binding property is also relatively poor, if vermiculite is formed with the material of shape; Must need a large amount of full-bodied tackiness agents, through high pressure, high temperature process moulding, a large amount of full-bodied tackiness agents has not only increased the manufacturing cost of vermiculite warming plate; And have a strong impact on the feature of environmental protection of vermiculite goods, reduce the burning rank of material.Development energy-saving and environmental protection, safety, life-span building heat preservation long, cheap, easy construction are the task of top priority of industry, enterprise and society.
Summary of the invention
The objective of the invention is to avoid the deficiency of prior art that a kind of vermiculite composite thermal insulation materials is provided, it is high to solve the inorganic heat insulation material cost, problems such as construction difficulty.
For realizing above-mentioned purpose, the technical scheme that the present invention takes is: a kind of vermiculite composite thermal insulation materials, comprise major ingredient A, B and auxiliary material A, B, and it is characterized in that the weight part of described major ingredient A, B is:
Major ingredient A: granularity is 30-100 purpose vermiculite 1-8 part;
Major ingredient B: resol 1-8 part;
Said auxiliary material A be by talcum powder, whipping agent, promoting agent, softening agents and solidifying agent by arbitrary proportion blended mixture, its weight part is the 25-45% of major ingredient B;
Said auxiliary material B is a short glass fiber, and its weight part is to be no more than 10% of major ingredient B.
Said lagging material preparation method comprises the steps:
(1) selection by winnowing: vermiculite through selection by winnowing, is removed impurity and dust, obtain clean vermiculite raw material;
(2) pre-treatment: according to the above ratio the vermiculite after the selection by winnowing is put into the sulphuric acid soln that concentration is 2.5mol/L, temperature of reaction is 105-112 ℃, and the reaction times is 1.8-2.2h, vermiculite is constructed modify and organic process;
(3) foaming: according to the above ratio resol, talcum powder, whipping agent, promoting agent, softening agents and solidifying agent are added in the foaming machine successively, foam being not less than under 20 ℃ of normal temperature, process foamed phenolic resin;
(4) toughness reinforcing processing: in foamed phenolic resin, add short glass fiber according to the above ratio, stir;
(5) injection molding: pretreated vermiculite drop from sulphuric acid soln is gone out; Put into foamed phenolic resin then and stir, the 1-2% that presses vermiculite weight again adds rubber powder, adds 0.8-1.2 kilogram corrosion inhibitor by one cube of vermiculite simultaneously; Inject mould, moulding in 3-5 hour after stirring.
In the said injection step, add cement cloth or non-woven fabrics in the mould top and bottom, with the folding strength that increases finished product and with the bounding force of buildings.
Said corrosion inhibitor is quicklime, red stone, lime carbonate or Borax pentahydrate.
The invention has the beneficial effects as follows:
1, with China thing hide abundant, inexpensive, do not fire, the vermiculite of heat-insulating property excellence is the main body; It is carried out the organic process of physics, chemical property; Realize the best complex basic point with organic foaming phenolic aldehyde, maximization extracts the advantage coexistence complementation of these two kinds of materials, reaches the burning rank A level of highest level; Reduced the manufacturing cost of A level lagging material significantly, cost is low, performance good;
2, in vermiculite and foaming phenolic aldehyde recombination process; Increase spun glass, softening agents, solidifying agent etc., strengthen each item performance index of vermiculite composite fireproof lagging material, the hydrophobic nature of inorganic A level lagging material is carried to the limit; High insulating effect; Alkali-free, Halogen, the serious consequence that fundamentally avoided returning efflorescence behind halogen, the anti-alkali, embrittlement, comes off is a kind of composite multi-functional lagging material that meets very much the development trend of international building lagging material;
3, this lagging material all adopt nontoxic, innoxious substance is compound is mixed, and can not form building waste, direct backfill farmland after the corner blanking is pulverized does not have harm to the farmland, the major ingredient vermiculite also plays soil and preserves moisture, the effect of constant humidity.Simultaneously; Vermiculite does not have carbon and element sulphur, contains hydrogen, oxygen, carbon in the phenolic aldehyde molecular configuration, and they do not burn, do not melt in 1000 ℃ of raging fires; The very high temperature differentiation phase; The gas that overflows is also nontoxic, tasteless, and vermiculite, phenolic aldehyde are all nontoxic, harmless material, agrees with country's requirements of green environmental protection;
4, applied range is used for that the very high building heat preserving of fire protection requirements such as building roofing insulation, building masonry wall insulation, steel-structure factory building, large scale industry factory building, prefabricated house, freezer, dust proof workshop, one off houses, gymnasium, supermarket, the insulation of floor heating engineering, square ground, ground frost heave control (airstrip, super highway) are heat insulation, insulation works etc.
