Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation felt, in particular to a composite high-temperature resistant thermal insulation felt. Background Art

[0002] Thermal insulation blankets should possess numerous advantages, including high thermal insulation, windproof, rain and snowproof, aging resistance, flame retardancy, strong water resistance, dustproof, moisture-proof, acid and alkali resistance, easy retraction, and long service life. Traditional insulation covering materials, including straw mats, cattail mats, paper quilts, and cotton quilts, have the following disadvantages: they are heavy and labor-intensive to roll up and unroll. When soaked by rain or snow, they not only increase weight but also reduce thermal insulation performance. Furthermore, they can cause serious contamination of the film and easily reduce light transmittance. New thermal insulation blankets have made some progress in overcoming these drawbacks. An ideal thermal insulation blanket should have a low heat transfer coefficient, good thermal insulation, moderate weight, easy roll-up, good wind and water resistance, and long service life. However, most current thermal insulation blankets are made of a single material, which results in poor thermal insulation performance at high temperatures and low practicality. Therefore, we propose a composite high-temperature-resistant thermal insulation blanket. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a composite high-temperature resistant thermal insulation felt. The first felt body and the second felt body are combined to make the thermal insulation felt have the functions of high temperature resistance, sound absorption and heat preservation. The protective cloth provided can effectively prevent the problems of insect infestation and mildew, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a composite high-temperature resistant thermal insulation felt, comprising a first felt body and a sealing strip;

[0005] The first felt body has an adhesive ring fixed to the outer side of the rear side, and the rear side of the adhesive ring is connected to the front side of the second felt body. The first felt body is a rock wool insulation felt, and the second felt body is a glass fiber thin felt. The rear side of the second felt body is bonded with a protective cloth made of non-woven fiber and bamboo charcoal fiber. The sealing strip is bonded to the outer sides of the first and second felt bodies.

[0006] Wherein, it also includes an adhesive strip and a release film. The adhesive strip is evenly distributed on the front side of the first felt body, and the release film is bonded to the front side of the adhesive strip.

[0007] The first felt body is combined with the second felt body to make the insulation felt resistant to high temperatures, sound-absorbing and heat-insulating. The protective cloth can effectively prevent insect damage and mildew, while the adhesive strip facilitates the quick installation of the insulation felt, making it suitable for different installation situations.

[0008] Furthermore, it also includes placement holes and desiccant, the placement holes are evenly opened on the surface of the first felt body and the second felt body, and the desiccant is placed inside the placement holes. The desiccant inside the placement holes can absorb moisture inside the thermal insulation felt to prevent the thermal insulation felt from being damp and affecting its high temperature resistance.

[0009] Furthermore, it also includes a placement groove and a reinforcement pad. The placement groove is opened on the rear side of the first felt body, and a reinforcement pad is installed inside the placement groove. The reinforcement pad inside the placement groove can effectively increase the firmness of the thermal insulation felt to prevent external sharp objects from penetrating the thermal insulation felt.

[0010] Furthermore, it also includes flame-retardant cloth, which is fixed on the outer side of the protective cloth. The flame-retardant cloth is flame-retardant silicon-titanium fireproof cloth. The flame-retardant cloth can prevent the thermal insulation felt from contacting with flames and causing ignition.

[0011] Furthermore, it also includes a waterproof membrane, which is bonded to the outer side of the flame retardant cloth. The waterproof membrane is a polyurethane film. The waterproof membrane and the sealing strip can isolate external liquids to prevent external liquids from entering the interior of the thermal insulation felt and affecting its high temperature resistance.

[0012] Furthermore, it also includes a wear-resistant coating, which is evenly coated on the surface of the waterproof membrane. The wear-resistant coating is epoxy resin, and the wear-resistant coating can prevent the waterproof membrane from frequent contact and friction with external objects to cause wear.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the composite high temperature resistant thermal insulation felt has the following advantages:

[0014] 1. By combining the first felt body with the second felt body, the thermal insulation felt has the functions of high temperature resistance, sound absorption and heat preservation. The protective cloth can effectively prevent the problems of insect infestation and mildew, and the adhesive strip facilitates the quick installation of the thermal insulation felt, making it suitable for different installation situations.

[0015] 2. By placing the desiccant inside the hole, the moisture inside the insulation felt can be adsorbed to prevent the insulation felt from being damp and affecting its high temperature resistance. Placing the reinforcement pad inside the groove can effectively increase the firmness of the insulation felt to prevent external sharp objects from penetrating the insulation felt.

[0016] 3. The waterproof membrane and sealing strip can be used to isolate external liquids to prevent external liquids from entering the interior of the thermal insulation felt and affecting its high temperature resistance. BRIEF DESCRIPTION OF THE DRAWINGS
