Background technology
Along with the continuous rising of Global Temperature, the population of mosquito and quantity all will significantly improve, and just day by day threaten the health of the mankind.Mosquito sucks blood except directly stining thorn, harasses except sleep, more seriously propagates various diseases.The mosquito of China passes disease malaria, Filariasis, Japanese Type-B encephalitis and dengue fever (or dengue hemorrhagic fever) four class, and mosquito passes more important virosis and also has yellow fever and various equine encephalitis etc.The research of current various mosquito proof product, as the mosquito-repelling function of anti-mosquito cloth, but along with the raising along with people's living standard, carpet is more and more applied to hotel, aviation, hotel, office building, the industry-by-industries such as household.Carpet is as a kind of pavement, and have the advantage of its uniqueness, noise is little, comfortable foot feeling, absorbs dust, attractive in appearance etc., but also there are its some shortcomings, such as not easily arrange.Add insect-proof agent in carpet, have efficient protective action, such as all kinds of mosquito, flea, ant, cockroach, housefly, acarid, bedbug, flat lice, carpet beetle etc. has obvious avoidance effect, even can drive away house pet parasite with it, make pet from the invasion of disease and pest.And this product has water-fastness and dry-cleaning, heat-resistant stability is good, can remove in waste water treatment plant, to advantages such as people are harmless.So it is necessary for adding insect-proof agent for preventing parasitic existence in carpet, but the vermins-proof effect of carpet is undesirable at present, and is not suitable for promoting the use of.
Summary of the invention
Goal of the invention of the present invention is for deficiency of the prior art, provides the mosquito dispersing carpet that a kind of mosquito repelling rate is high.
The present invention is achieved by the following technical solutions:
A preparation technology for mosquito dispersing carpet, comprises carpet printing, fixation, washing, vacuum dehydration, Shi Pao, oven dry, inspection, packing, finished product.
Above-mentionedly execute bubble, stoving process is, first with foam device foaming, obtain solution, and regulating PH to 5 with citric acid, liquid-vapour ratio is 1:40, and output foam quality is 25g/L, then bubble is executed, every square of carpet 100 grams of foams, liquid carrying rate 10%, speed: 1.3-1.7m/min, finally by pressure roller extruding, pressure is: 1.5-2pa, foam is crushed and is coated in carpet surface uniformly, then carpet enters four joint oven for drying, bake out temperature 80-130 DEG C under guipure drives.
In above-mentioned foam device, solution used comprises:
Insect-proof agent 50-100g/L
Blowing agent 5g/L
Namely blowing agent is applied to the foaming agent that foam process does Final finishing processing, buys producer: chemistry is received in holder, constituent: organic and inorganic salt solution, containing triethanolamine, alkylbenzene sulfonate, and model blowing agent SBL.
Reinforcing agent NanoPU100g/L and polyurethane BAYPRETNanoPU.
Above-mentioned color fixing process is specially: temperature 128 degree, is incubated 3 minutes.
Above-mentioned washing process is specially: carry out spray washing after printed carpet color fixation, water temperature 35 degree.
Above-mentioned vacuum dehydration: vacuum pump pressure 3-5Pa, water is siphoned away by vacuum water absorber by the drugget blanket face after washing;
Above-mentioned carpet enters four joint oven for drying under guipure drives, and the speed of guipure is: 1.3-1.7m/min.
The constituent of above-mentioned insect-proof agent by volume mark comprises 50% butyldiglycol, 10% Permethrin, 20% aryl benzene polyoxy diene ether and 20% water.
The structural formula of aryl benzene polyoxy diene ether:
Wherein the scope of n is 50-200, and molecular weight is 1000-4000.
The invention has the beneficial effects as follows: the present invention by suitably adding insect-proof agent and the reinforcing agent NanoPU of certain PH in the preparation technology of carpet, effectively improve the mosquito repelling rate of carpet, and by liquid-vapour ratio during strict control foaming, execute the roll extrusion stoving process of the quality of the foam of bubble, addition, liquid carrying rate and foam, make the mosquito repelling rate of carpet of the present invention bring up to more than 98%, there is obvious progress.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described, so that those skilled in the art better can understand the present invention, but therefore do not limit the present invention.
