Abstract
The present invention provides a composite thermal-isolating material. The present invention comprises 40 to 50% (weight) of light inorganic materials, 35 to 45 (weight) of organic materials, 4 to 6% (weight) of surface active agents and 8 to 10% (weight) of adhesives, wherein the light inorganic materials are sepiolite, asbestos, rock wool, rock wool, glass fibers and aluminium silicate fibers, and the organic materials are organic hard foam materials. The composite thermal-isolating material of the present invention has the advantage of favourable low-temperature and thermal-isolating effect, use temperature is from-45 DGE C to 200 DGE C, the present invention can be directly coated and can be manufactured into various thermal-isolating materials.
Description
The present invention relates to a kind of lagging material, particularly a kind of composite heat-insulated material.
Existing lagging material is generally thermal insulation inorganic material, be mainly used in the heat-insulation and heat-preservation (CN87102864A) of high-temperature area, bigger at its thermal conductivity of low-temperature region, heat insulation and preservation effect is undesirable, and intensity is low, also useful porous plastics section bar is made lagging material, but use temperature is at 60 ℃-80 ℃, and inconvenience is used for special-shaped insulating equipment insulation.
The objective of the invention is to overcome above-mentioned shortcoming, a kind of composite heat-insulated material in low-temperature region-45 ℃-200 ℃ of uses is provided.
Composite heat-insulated material of the present invention mainly is composited by light inorganic material and organic materials, it consists of: light inorganic material 40-50% (weight), organic materials 35-45% (weight), tensio-active agent 4-6% (weight), binding agent 8-10% (weight).Base-material 80-90% (weight) in the light inorganic material wherein, be a kind of in sepiolite, the asbestos, but because asbestos are raphioid fibers, be carcinogenic substance, abroad ban use of, preferably use and be the clavate fiber, and the sepiolite harmless to HUMAN HEALTH, strongthener 10-20% (weight), be in rock wool, mineral wool, glass fibre, the aluminum silicate fiber one or more, organic materials is the polystyrene rigid foam, a kind of in hard polyurethane foam and the urine aldehyde foam, can be the particle after section bar or the pulverizing, granularity be generally 5-10 orders.
Tensio-active agent of the present invention is an ionogenic surfactant, as anion surfactants such as fast T, cats products such as glycol ether are selected the kind regulation of the kind of tensio-active agent by base material for use, when making base material, generally use the glycol ether cats product with sepiolite.
Binding agent of the present invention is an at least a mixture at least a and the organic binder bond polyvinyl alcohol, 712,831 in mineral binder bond water glass or the aluminum phosphate, generally select water glass and polyvinyl alcohol mixture for use, concentration of sodium silicate with 30-40% be advisable, polyvinyl alcohol is the aqueous solution, be generally 1: 5-1 with the ratio of water: 15.
Composite heat-insulated material of the present invention is the composite heat-insulated material of two kinds of forms, first mixed type composite heat-insulated material, be that light inorganic material is mixed with organic materials, cooperation is made with tensio-active agent and binding agent, add a certain amount of water and make slurry, can directly be coated on equipment and the buildings, or make section bar and use, it two is coating binding type composite heat-insulated materials, be that light inorganic material is cooperated with tensio-active agent and binding agent, add a certain amount of water and make slurry, be coated on the rigid foam section bar surface and make.
Need use the water of certainweight when composite heat-insulated material of the present invention uses, its consumption is generally 5-7 times of composite heat-insulated material.
The key technical indexes of composite heat-insulated material of the present invention is as shown in table 1.
