Description

Greenhouse heat preservation quilt

Technical Field

The utility model relates to a greenhouse heat preservation quilt belongs to greenhouse heat preservation quilt technical field.

Background

The existing greenhouse heat preservation quilt mainly comprises a middle cotton core and protective layers sewn on two sides of the cotton core, wherein the cotton core mainly plays a heat preservation effect, the protective layers on the two sides play a protection and heat preservation enhancing effect on the internal cotton core, the protective layers are generally woven by fiber materials such as nylon and the like, the protective layers formed by the weaving mode have general performances such as oxidation resistance, acid and alkali resistance, severe cold resistance and the like, can be used outdoors in high-cold and high-heat areas with large temperature difference, long sunshine time and strong ultraviolet rays, and have short service life, so that the existing greenhouse heat preservation quilt is limited in applicable areas and outdoor environments; on the other hand is when being connected inoxidizing coating and inside cotton core, generally adopts to make inoxidizing coating and cotton core up as an organic whole, because inoxidizing coating self waterproof nature is not enough and the pinhole that forms after making up permeates water easily again, in case meet sleet weather, makes the cotton core of whole heat preservation quilt wet thoroughly very easily, and the thermal insulation performance of heat preservation quilt will be discounted greatly this moment, moreover, if the heat preservation quilt after wet thoroughly can not in time effectual airing, then can influence the life of whole heat preservation quilt. In addition, this further deteriorates the heat retaining property and water resistance of the entire heat retaining cover.

In view of the above, a greenhouse heat preservation quilt with heat preservation and waterproof properties is needed.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

Example one

A greenhouse heat preservation quilt is characterized in that a quilt body of the greenhouse heat preservation quilt mainly comprises a middle cotton core 1, and an outer protective layer 21 and an inner protective layer 22 which are compounded on two sides of the cotton core 1, wherein the middle cotton core 1 adopts an integral cotton core with a certain thickness, the outer protective layer 21 and the inner protective layer 22 are fixedly bonded on the upper surface and the lower surface of the cotton core 1 through adhesive layers 6, and the adhesive layers 6 are bondedAn aqueous subbing layer was used. The outer protective layer 21 and the inner protective layer 22 are mainly used for protecting the cotton core 1 of the inner interlayer, preserving heat and preventing water, and the outer protective layer 21 is directly exposed to the external environment when in use, so that the outer protective layer 21 is made of PVC (polyvinyl chloride) knife scraping cloth which is composed of a middle light guide fiber interlayer 31 and PVC films 41 hot-pressed on two sides of the light guide fiber interlayer 31. Since the inner protective layer 22 covers the outer protective layer 21 and the cotton core 1 during use, the inner protective layer 22 may be constructed by using a PE woven fabric 31a in the middle and PE films 41a laminated on the upper and lower surfaces of the PE woven fabric 31a in consideration of cost. In this example, the gram weight of the knife scraping cloth is 500g/m ² The gram weight of the cotton core is 500-1400 g/m ² The gram weight of the PE woven cloth is 200 g/m ² . The heat preservation quilt is provided with the sewing connection part for sewing the cotton core 1, the outer protective layer 21 and the inner protective layer 22 together on two sides in the length direction, so that two independent heat preservation quilts are combined together, the nylon fastener tape 5 is sewn on the surface of the sewing connection part selectively, and two adjacent and independent heat preservation quilts can be lapped together through the nylon fastener tape 5.

Example two

The difference between this embodiment and the first embodiment is that the outer protective layer 21 and the inner protective layer 22 both use the same structural layer, that is, both use PVC knife cloth.

EXAMPLE III

The difference between the present embodiment and the first embodiment is that the two sides of the heat preservation quilt in the width direction are coated with the third protection layer 23, and the third protection layer 23 includes a longitudinal vertical surface 23-1 compounded on the side of the cotton core 1, an upper attaching surface 23-2 attached to the top surface of the cotton core and pressed on the lower portion of the outer protection layer 21, and a lower attaching surface 23-3 attached to the bottom surface of the cotton core and pressed on the upper portion of the inner protection layer 22.

The utility model discloses a big-arch shelter keeps warm by adopts the structure of integral cotton core and the compound inoxidizing coating of two sides, and the selection of inoxidizing coating can improve the anti-oxidant, anti oxygen outside line, acid and alkali-resistance and the cold-resistant performance such as by a wide margin and keep warm to make the application region scope of heat preservation quilt unrestricted more, ensure its performance and the life-span that the big-arch shelter kept warm by under extreme environment. The compound mode of gluing combination has avoided the quilt body because of sewing the pinhole that produces, will keep warm by length direction's both sides limit make up and combine nylon fastener tape and quilt body simultaneously, can keep warm the multi-disc quilt according to not unidimensional needs and carry out the overlap joint combination, and the pinhole of making that exists at the faying face is because of the number of piles is more and comparatively fine and close to only at the avris, with middle cotton core's area of contact very limited, consequently still can keep better waterproof nature. Compared with the traditional multilayer sewn cotton core, the integral cotton core is easier to roll and release, and the heat insulation performance is better than that of the layered sewn cotton core.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
