Household fireproof smoke-proof adhesive tape
Technical Field
The invention relates to the field of fire fighting, in particular to a household fireproof and smoke-proof adhesive tape.
Background
In a fire accident, the main causes of fire death are high temperature of smoke and asphyxiability of CO, and the secondary causes are toxicity of other components of smoke, irritation of smoke, anoxic property, shading property and the like. More than 80-90% of people are killed by toxic and harmful smoke in fire. Modern high-rise and super high-rise buildings are increasingly popularized, once a fire disaster occurs, an elevator cannot be used, the stair has a chimney effect, the upward spreading speed of smoke is far higher than the escape speed-the upward spreading speed of smoke is 3-5 meters per second, the time from one floor to the top floor is not more than 30 seconds, a strong person goes to the top floor for at least 2-120 seconds, and the building is old, young, women and children. Therefore, the current standard is that once the escape cannot be found, people do not need to flee from the corridor, the door and window seams and the like are sealed by wet towels, smoke and flame are reduced, and the escape waiting for rescue is realized. Many cases have shown that it is difficult to find a suitable object to quickly and completely block the door opening to prevent the ingress of high temperature toxic fumes during the rush hours because of the small door opening. The adhesive tape can be used for conveniently plugging gaps, but the existing industrial high-temperature adhesive tape such as a Teflon adhesive tape can only reach more than 200 ℃, and when meeting high-temperature smoke of more than 500 ℃ of a fire, the adhesive tape can be immediately degummed, deformed and dropped, so that the fire smoke can not be rapidly and effectively prevented from invading, toxic substances such as highly toxic byproducts, namely fluophosgene, perfluoroisobutylene and the like are generated during high-temperature cracking, and the toxic substances are emitted, thereby being harmful to human health. At present, no domestic quick fire smoke prevention device for a system is used for quickly blocking a door gap to escape and save self when a fire disaster can not escape.
Disclosure of Invention
The invention aims to provide a household fireproof and smoke-proof adhesive tape.
The technical solution for realizing the purpose of the invention is as follows: the utility model provides a domestic fire prevention smoke protection sticky tape, includes adhesive layer, barrier layer, baseband layer, leaves type coating, seal box, and wherein adhesive layer, barrier layer, baseband layer, leave type coating and set gradually and constitute the sticky tape body, and the seal box is used for storing the sticky tape body.
Furthermore, the adhesive layer is made of epoxy resin and/or phenolic resin adhesive.
Furthermore, the material of the barrier layer adopts high silica fiber cloth.
Furthermore, the base belt layer is made of glass fiber fireproof cloth.
Furthermore, the release coating is made of one or more of a high-molecular copolymer of acrylic acid-styrene ester, organic silicon and polyethylene wax.
Further, the adhesive tape is in a strip or block form.
Compared with the prior art, the invention has the following remarkable advantages: the fire disaster smoke-blocking device is simple and convenient to use, safe and reliable, and capable of effectively blocking gaps for a long time, preventing fire disaster smoke from invading indoors through door gaps and the like, and greatly improving the survival probability of fire disasters.

Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings.
As shown in fig. 1-2, the household fireproof and smoke-proof adhesive tape of the invention comprises an adhesive layer 1, a barrier layer 2, a base tape layer 3, a release coating 4 (a release agent), and a sealing box (a cartridge), wherein the adhesive layer 1, the barrier layer 2, the base tape layer 3, and the release coating 4 are sequentially arranged to form an adhesive tape body, and the sealing box is used for storing the adhesive tape body. When in use, the sealing tape is taken out from the sealing box (cylinder) and is pressed along the door seam. Can effectively prevent fire smoke from invading for a long time and increase the escape chance of the fire.
The adhesive layer 1 is made of materials including but not limited to epoxy resin adhesives and phenolic resin adhesives, and has the following functions: the strong adhesive force is attached to two sides of the door gap to provide a compression force to fix the isolation layer 2 so as to tightly seal the door gap and prevent the high-temperature fire smoke from invading. The material of the barrier layer 2 comprises but is not limited to high silica fiber cloth, and the functions of the barrier layer are as follows: the blocking door gap bears the fire hazard high temperature toxic smoke to prevent the fire hazard high temperature toxic smoke from invading. The material of the base belt layer 3 comprises but is not limited to glass fiber fireproof cloth. The function is to provide a bearing body for the adhesive layer 1 and the barrier layer 2, and further isolate the invasion of high-temperature toxic gas by the characteristic of high-temperature heat insulation. The release coating 4 includes, but is not limited to, acrylic-styrene ester high molecular copolymer, silicone, polyethylene wax, etc., and functions as: the adhesive layer 1 does not need to stick the base belt layer 4, and the adhesive layer is convenient and quick to stick.
As a preferred embodiment, the household fire and smoke protection tape is in the form of a strip for door seam application or a block for covering application of the entire door.
