Description
Technical field
the utility model relates to protective casing field, relates more specifically to a kind of high temperature resistant, anti-puncture flexible insulating sleeve that can be widely used in automobile, motor, Aeronautics and Astronautics field.
Background technology
acrylic acid insulating sleeve, as a class important in insulating sleeve product, has excellent insulation property and good fire-retardant, low temperature resistant and resistance to chemical corrosion, can be widely used in the fields such as automobile, motor, Aeronautics and Astronautics.But along with the industrial expansion such as automobile, motor, automobile, electric motors function and application are more and more wider, and structure also becomes increasingly complex, also more and more less for the space of assembling.In this case, traditional acrylic acid insulating sleeve is comparatively large due to hardness, under limited installing space and complicated mounting condition, is not easy to install, uses more and more not convenient; And due to complex structure, insulating sleeve has very most bending after assembling, if sleeve pipe is harder, be easy to be worn, break, lose insulation, fire-retardant etc. protective action.Thus, the conventional insulator sleeve pipe premium properties that needed one to take into account and the good insulating sleeve of toughness.
Summary of the invention
in order to overcome the problems referred to above of the prior art, the utility model provides a kind of flexible insulating sleeve, and it has good pliability and smooth surface, and intensity is high, not easily breaks.
the technical solution adopted in the utility model is: a kind of flexible insulating sleeve, comprise body and cover the cover layer of outer surface of tube body, body is formed by fiberglass braided, cover layer comprises the inner covering layer being close to outer surface of tube body and the outer cover covered on inner covering layer outer surface, inner covering layer is made up of water soluble acrylic acid, and outer cover is made up of polyurethane-modified acrylic acid.
preferably, above-mentioned polyurethane-modified acrylic acid is polyurethane-modified water soluble acrylic acid.
polyurethane-modified water soluble acrylic acid is a kind of known materials, can obtain from the approach of being purchased, and carries out modification and obtain by polyurethane to water soluble acrylic acid.Water soluble acrylic acid is widely used in the field such as adhesive, coating owing to having the advantages such as stability, weatherability, light resistance, chemical-resistant and environmental protection, can improve acrylic acid performance to the modification of water soluble acrylic acid, the kind of the water-borne acrylic resin of modification has epoxy modified aqueous acrylic acid resin, polyurethane aqueous water-borne acrylic resin etc.
preferably, the cross section outer rim of inner covering layer is circular, and the thickness of the thinnest part of inner covering layer is 0~
0.1mm.When the thickness of thinnest part is 0mm, water soluble acrylic acid just fills up the gap between the surface of adjacent glass fibers.
see further, the thickness of outer cover is 0.1~
0.7mm.
preferably, the thickness of outer cover is 0.3~
0.5mm.
further, the thickness of body is 0.1~
0.7mm.
further, the thickness of body is 0.2~
0.6mm.
preferably, the internal diameter of body is 0.5~
50mm.
compared with prior art, the present invention has the following advantages: the utility model provides a kind of flexible insulating sleeve, it comprises fiberglass braided body and cover layer, cover layer comprises inner covering layer that water soluble acrylic acid makes and the outer cover that polyurethane-modified acrylic acid is made, and overcome at least the following problem existing for traditional acrylic acid insulating sleeve: hardness is higher; Under limited installing space and complicated mounting condition, be not easy to install; Use more and more not convenient.In addition, due to complex structure, insulating sleeve has very most bending after assembling, if sleeve pipe is harder, be easy to be worn, break, lose insulation, fire-retardant etc. protective action, the utility model flexible insulating sleeve then overcomes the problems referred to above completely.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation of flexible insulating sleeve of the present utility model;
in figure: 1, body; 2, inner covering layer; 3, outer cover.
Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature be easier to be readily appreciated by one skilled in the art, thus protection range of the present utility model is made more removes clear and definite defining.
consult Fig. 1, Fig. 1 illustrates according to a preferred embodiment of the present utility model, as can be seen from the figure, the flexible insulating sleeve of this embodiment of the present utility model, comprise body 1 and cover the cover layer of body 1 outer surface, body 1 is formed by fiberglass braided, cover layer comprises the inner covering layer 2 being close to body 1 outer surface and the outer cover 3 covered on inner covering layer 2 outer surface, wherein inner covering layer 2 is made up of water soluble acrylic acid, and outer cover is made up of polyurethane-modified water soluble acrylic acid.
particularly, inner covering layer 2 comprises the part of filling between adjacent glass fibers, and the cross section outer rim of inner covering layer 2 and outer cover 3 is circle, and the thickness of the thinnest part of inner covering layer 2 is 0.05mm.The thickness of outer cover 3 is 0.4mm.More specifically, the thickness of body 1 is 0.5mm.The internal diameter of body 1 is 5mm.
the cover layer of flexible sleeve of the present utility model comprises inner covering layer and outer cover, and inner covering layer is made up of water soluble acrylic acid, mainly plays the effect outer surface of glass embryonic tube being carried out to basis coating, can ensure the gluing effect of outer cover like this.Outer cover is made up of the water soluble acrylic acid of polyurethane PU modification, this modified acroleic acid material is being widely used in the fields such as elastomeric roof, the water soluble acrylic acid material of this modification has the features such as intensity after high resiliency, high viscosity, film forming is high, smooth surface, being applied on insulating sleeve of the present utility model to make insulating sleeve have good pliability, and smooth surface intensity is high, not easily breaks.In the utility model, inner covering layer is very important, because if directly with the water soluble acrylic acid gluing of PU modification, and do not arrange inner covering layer, glue is rarer, can flow down along embryonic tube, affects gluing effect.Inner covering layer and outer cover combine and can ensure that flexible insulating sleeve of the present utility model is on the basis of premium properties ensureing conventional insulator sleeve pipe, has better pliability, and handling ease.
the utility model take glass fibre as body, and water soluble acrylic acid inner covering layer and polyurethane-modified water soluble acrylic acid outer cover make sleeve pipe have more pliability on the basis ensureing traditional sleeve premium properties.
flexible insulating sleeve of the present utility model realizes by the technique optimizing existing acrylic acid sleeve pipe, make it for the production of pliability acrylic acid sleeve pipe.
in the technique of this optimization:
a () uses double-deck gluing method, first gluing, for carry out preliminary treatment to embryonic tube, effectively can prevent the dry phenomenon of product foaming, glue.
b () steel ball and sponge are combined, make that product appearance is more smooth, rounding.
c () optimizes the parameters such as production process temperature, speed, the high-quality of products quality guarantee, stable.
the utility model makes cover layer by using special acryhic material, and optimizes photoresist coating process, successfully develops and has good flexible flexible insulating sleeve.This product pliability is good, is easy to install, and insulation, fire-retardant, decay resistance good, and when bending, distortion also can keep self character, the completely competent industry such as Hyundai Motor, motor is for the rigors of this series products.
above specific embodiment of the present invention is illustrated; but protection content of the present invention is not only limited to above embodiment; in art of the present invention, the usual knowledge of a GPRS, just can carry out diversified change within the scope of its technology main idea.
