Abstract
The invention discloses a manufacturing process of flame-retardant water curtain paper, which is made of kraft paper, a flame retardant, red glue and white glue, and comprises the following production steps: mixing, soaking, baking, shaping, gluing, laminating, secondary baking and cutting to obtain a finished product; a mixing procedure: mixing the water-insoluble flame retardant, the red glue and the water according to the ratio of 1: 3, and stirring by a stirrer or manually in a solution tank all the time to ensure that the flame retardant is uniformly attached to kraft paper; gluing: and (3) fully mixing the water-insoluble flame retardant and the white glue according to the ratio of 1: 1, and coating the mixture on the surface of the formed kraft paper. The manufacturing process of the fire-retardant water curtain paper enables the water curtain paper which does not have fire retardancy originally to have excellent fire retardancy, the red glue and the white glue have thermosetting property, the fire retardant can be permanently fixed on kraft paper after baking and curing, and the water curtain paper has permanent fire retardancy without influencing wettability.
Description
Technical Field
The invention relates to the field of water curtain paper manufacturing, in particular to a manufacturing process of flame-retardant water curtain paper.
Background
The water curtain paper is mainly used for air precooling of an air cooler and direct cooling of occasions such as common plants, office buildings, markets and the like, and in summer and autumn, because the air temperature is high, the field air temperature is reduced by using water curtain equipment, and the water curtain needs to be wetted during working, so that the hidden danger of flammability does not exist; and the environmental temperature in spring and winter is low, the equipment is in the shutdown time period, and the water curtain paper is in the dry environment, so the requirement on the flame retardant property of the product in spring and winter is high, and the excellent flame retardant property can be achieved in the equipment shutdown time period. The existing water curtain paper has the following flammable hidden troubles: 1. the existing water curtain paper consists of: the craft paper, red glue, white glue are composed, the craft process is: mix, soak, toast, design, rubber coating, layer glue, the secondary is toasted and is tailor the finished product, wherein mixing process: red glue and water in a ratio of 1: 3, and the gluing process comprises the following steps: the white glue accounts for 100 percent, and the kraft paper, the red glue and the white glue are all inflammable materials and can be violently combusted in case of open fire; 2. even if the existing water curtain paper finished product has flame retardance temporarily after being soaked in a flame retardant solution dissolved in water, the flame retardant can be crystallized and separated out on the surface of the water curtain paper after being used for a period of time, so that the wettability and the attractiveness of the water curtain paper are influenced, and the water curtain paper can be taken away after being used for a period of time due to the fact that the flame retardant is dissolved in water, so that the flame retardant effect of the water curtain paper is lost.
Disclosure of Invention
The invention aims to provide a manufacturing process of flame-retardant water curtain paper, which aims to solve the problems in the background technology. In order to achieve the purpose, the invention provides the following technical scheme: the manufacturing process of the flame-retardant water curtain paper comprises the following production steps: mixing, soaking, baking, shaping, gluing, laminating, secondary baking and cutting to obtain the finished product.
Mixing: mixing a water-insoluble flame retardant, red glue and water in proportion, wherein the red glue is added with water to dilute a glue solution, so that the concentration of the glue solution is reduced, and the operation is facilitated; because the flame retardant is insoluble in water and red glue, the flame retardant is required to be fully stirred for preventing the flame retardant from precipitating and ensuring the uniformity of the flame retardant in glue solution;
the wetting is as follows: soaking kraft paper in a mixed solution of a flame retardant, red glue and water, wherein the mixed solution of the red glue is always in a stirred state in the soaking operation;
baking: putting the soaked kraft paper into an oven for baking, and evaporating water;
and (3) shaping: pressing the dried kraft paper into a corrugated shape by a corrugating machine, and heating the kraft paper to a permanent curing temperature while pressing by the corrugating machine so as to cure the kraft paper into a corrugated shape;
gluing and laminating: mixing a water-insoluble flame retardant and white glue in proportion, smearing the mixture on corrugated kraft paper, and completing multi-layer bonding; the mixed liquid of the white glue and the fire retardant is always in a stirred state in the process;
and (3) secondary baking and cutting to obtain a finished product: and (3) putting the multi-layer corrugated kraft paper which is bonded into a whole into an oven for secondary baking, and cutting the kraft paper into a finished product according to the required shape after baking.
Preferably, the mixing is carried out by mixing the flame retardant which is insoluble in water, the red glue and the water according to the ratio of 1: 3.
Preferably, the glue coating, the water-insoluble flame retardant and the white glue are mixed according to the ratio of 1: 1.
Compared with the prior art, the invention has the following beneficial effects: the kraft paper which does not have the flame-retardant property originally has excellent flame retardance, because the used flame retardant is not dissolved in water, the red glue and the white glue have thermosetting property, the flame retardant can be permanently fixed on the kraft paper after baking and curing, and the flame retardance of the kraft paper is increased while the wettability is not influenced.
Drawings
FIG. 1 is a schematic view of the process flow structure of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the flame-retardant water curtain paper is made of kraft paper, a flame retardant, red glue and white glue, and the making process comprises the following production steps: mixing, soaking, baking, shaping, gluing, laminating, secondary baking and cutting to obtain the finished product. Mixing, namely mixing the flame retardant, the red glue and the water which are insoluble in water according to the ratio of 1: 3, and stirring by a stirrer or a manual work in a solution tank all the time, wherein the flame retardant is insoluble in water and can be better attached to kraft paper after being fully stirred. Wet out, kraft paper was fully soaked in the solution. And (4) baking, namely putting all the wetted kraft paper into an oven for baking. And (4) shaping, namely, entering a corrugating machine for shaping after baking. And gluing, namely mixing the water-insoluble flame retardant and the white glue according to the ratio of 1: 1, and coating the mixed glue on the shaped kraft paper. And (4) layer bonding, namely bonding the kraft paper coated with the white glue layer by layer. And (5) secondary baking, namely performing secondary baking through an oven. Cutting into final product, and cutting into final product according to size. Through the process treatment, the water curtain paper which is not provided with flame retardance originally has excellent flame retardance, because the used flame retardant is not dissolved in water, the red glue has thermosetting property, the flame retardant can be permanently fixed on kraft paper after baking and curing, and the flame retardance of the kraft paper is increased while the wettability is not influenced.
