Abstract
The utility model relates to a kind of V-type groove polyurethane heat-insulation structure, it is characterized in that: this insulating structure is placed with lower floor's polyurethane (1), surge layer polyurethane (2), upper strata polyurethane (3) and polyureas (5) from top to bottom successively, described surge layer polyurethane (2) is in corrugated and be covered in the surface of lower floor's polyurethane (1), described upper strata polyurethane (3) covers surge layer polyurethane (2), the top on described upper strata polyurethane (3) offers a V-type groove (4), and the surface on described upper strata polyurethane (3) is covered with one deck polyureas (5).When this V-type groove polyurethane heat-insulation structure is caught a cold, collapsible area is larger, laterally shrinks under cryogenic, instead of inwardly, so just can effectively stop thermal insulation layer to rupture.
Description
Technical field
The utility model relates to a kind of V-type groove polyurethane heat-insulation structure, in the insulating structure for the container such as insulation pipe, heat insulation tank peculiar to vessel.
Background technique
In natural gas carrier vessel, store the tank of liquid methane and pipeline wherein by different materials with can guarantee that the blocking layer of sealing forms.For storage and the transport of the liquid methane-163 DEG C of temperature, excellent insulation is indispensable.
In natural gas carrier vessel of new generation, be integrated into sealing in carrier (especially ship) structure and the tank of insulation and pipeline comprise two continuous print sealing blocking layers, the first blocking layer contacted with the product held in tank and another be arranged on the second blocking layer between the first blocking layer and carrier structure, these two sealing blocking layers and two adiabatic blocking layers are alternately.Second blocking layer is used for the interim any seepage holding the Liquid that may occur through this first blocking layer.
When the second blocking layer on holding vessel and pipeline uses as its thermal insulation layer, smooth polyurethane surface cannot bear the contraction after turning cold at all, and suppleness is poor, and shrinkage area is little, causes thermal insulation layer to catch a cold easy-rupturing, have impact on heat insulation effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of V-type groove polyurethane heat-insulation structure is provided, compared to normally level and smooth polyurethane surface, when it makes insulating structure catch a cold, collapsible area is larger, laterally shrink under cryogenic, instead of inwardly, so just can effectively stop thermal insulation layer to rupture.
The purpose of this utility model is achieved in that
The utility model V-type groove polyurethane heat-insulation structure, this insulating structure is placed with lower floor's polyurethane, surge layer polyurethane, upper strata polyurethane and polyureas from top to bottom successively, described surge layer polyurethane is corrugated and is covered in the surface of lower floor's polyurethane, described upper strata polyurethane covers surge layer polyurethane, the top of described upper strata polyurethane offers a V-type groove, and the surface of described upper strata polyurethane is covered with one deck polyureas.
Compared with prior art, the beneficial effects of the utility model are:
This V-type groove polyurethane heat-insulation structure is by spraying on the surface of lower floor's polyurethane through a glass web, form corrugated, one deck upper strata polyurethane is sprayed subsequently on surge layer polyurethane, and offer V-type groove at upper strata polyurethane surface, last at upper strata polyurethane surface spray polyurea, the surface of the insulating structure that final spraying is formed is compared to normally level and smooth polyurethane surface, when catching a cold, collapsible area is larger, laterally shrink under cryogenic, instead of inwardly, so just can effectively stop thermal insulation layer to rupture.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model V-type groove polyurethane heat-insulation structure.
Wherein: lower floor's polyurethane 1, surge layer polyurethane 2, upper strata polyurethane 3, V-type groove 4, polyureas 5.
Embodiment
See Fig. 1, the utility model relates to a kind of V-type groove polyurethane heat-insulation structure, this insulating structure is placed with lower floor's polyurethane 1, surge layer polyurethane 2, upper strata polyurethane 3 and polyureas 5 from top to bottom successively, described surge layer polyurethane 2 is corrugated and is covered in the surface of lower floor's polyurethane 1, described upper strata polyurethane 3 covers surge layer polyurethane 2, the top of described upper strata polyurethane 3 offers a V-type groove 4, and the surface of described upper strata polyurethane 3 is covered with one deck polyureas 5.
This V-type groove polyurethane heat-insulation structure is by spraying on the surface of lower floor's polyurethane 1 through a glass web, form corrugated, one deck upper strata polyurethane 3 is sprayed subsequently on surge layer polyurethane 2, and offer V-type groove 4 on upper strata polyurethane 3 surface, last at upper strata polyurethane 3 surface spraying polyureas 5, the surface of the insulating structure that final spraying is formed is compared to normally level and smooth polyurethane surface, when catching a cold, collapsible area is larger, laterally shrink under cryogenic, instead of inwardly, so just can effectively stop thermal insulation layer to rupture.
