Description
Technical field
The present invention relates to building material technical field, relate in particular to one and build by laying bricks or stones and use high bond strength thermal insulation mortar.
Background technology
Thermal insulation mortar is taking various light materials as aggregate, taking cement as gelating material, admixes some property-modifying additives, is uniformly mixed and a kind of premixing dry powder and mortar of making through manufacturing enterprise. be mainly used in building exterior wall heat preserving, there is the advantage such as easy construction, good endurance.
Heat storage technology can be used for solving the contradiction of heat energy supply and demand mismatch; it is the important technology that improves efficiency of energy utilization and protection of the environment; the mode that can store mainly contains 3 kinds of sensible heat, latent heat and chemical reaction heats. and wherein latent heat mode utilizes phase-change material to absorb heat (cold) amount or emit heat (cold) amount to environment from environment in thing phase change process; thereby reach the object of storage and the release of energy; have thermal storage density large, hold the approximate isothermal of exothermic process, process is easy to control, and the advantage such as can be repeatedly used.
Paraffin is that a kind of hydro carbons extracting from some distillate of oil, shale oil or other pitch mineral oil is mixed Compound, main component is solid alkane, and odorless, tasteless is white or faint yellow translucent solid. and paraffin is noncrystal, but has Significantly crystal structure. generally usually adopt inexpensive technical grade paraffin as insulation material, technical grade paraffin is much hydrocarbon The mixture of compound, does not have fixing fusing point, only has a fusion temperature scope. and paraffin has much excellent as a kind of PCM Point, as high in latent heat of phase change, almost do not have surfusion, when fusing steam pressure low, be difficult for occurring chemical reaction and chemically stable Property better, spontaneous nucleation, be not separated and corrosivity, price is also lower etc.; But it also has some important shortcomings, such as heat conduction Coefficient is low and density is little, solid-liquid phase change etc. easily occurs. and directly use paraffin to make phase-change material and can bring inconvenience.
Microencapsulation refers to coated film or small solid particle, drop or the bubble of shell material spreading. and in recent years, microcapsules technology was widely used in the immobilization aspect of microorganism, animal and plant cells, enzyme and other various bioactivators and chemicals. and microencapsulated phase change material is exactly microcapsules technology to be applied to phase-change material and the NEW TYPE OF COMPOSITE phase transformation material Material. that forms
Patent CN101671149A discloses a kind of paraffin microencapsulated phase-change thermal-storage mortar and preparation method thereof, with The inorganic gel materials such as cement are matrix, mix the organic phase change material paraffin of microencapsulation, form and have the new of heat accumulation function Type external wall outer insulation material; Adopt coupling agent process for modifying surface and polymer fiber toughening technology, improved paraffin microcapsule With the compatibility .But of inorganic gel materials, microcapsule prepared by the method selects carbamide and formaldehyde as cyst material, is giving birth to Easily bring pollution during one-tenth process and use, be also unfavorable for environmental protection and safety.It addition, select to add coupling agent to improve paraffin Microcapsule and the compatibility of inorganic gel materials, its effect is the most obvious.
Sesbania gum (sesbania gum) is a kind of natural polysaecharides extracted in the seed endosperm by leguminous plant sesbania Polymer substance, it is mainly composed of D-galactose and D-MANNOSE, forms with 1:2.Sesbania gum can be used as food emulsifying agent, thickener and stabilizing agent, to improve the quality of food. this is mainly due to the water-soluble hydrophilic gel of its formation soluble in water, can make to increase Consistence, stability and emulsibility substantially increase.
Styrene-acrylic emulsion (styrene-acrylate emulsion) is to be obtained through emulsion copolymerization by styrene and acrylate monomer.
It is water-fast, alkaline-resisting, scrub resistance can be good, and resistance to outdoor aging is widely used in the field such as adhesive, coating..
