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 mankind's health.Mosquito sucks blood, harasses sleep except directly stining thorn, 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 classes, and mosquito passes more important virosis and also has yellow fever and various equine encephalitis etc.The research of current various mosquito proof products, as the mosquito-repelling function of anti-mosquito cloth, but is accompanied by the raising along with people's living standard, and carpet has more and more been applied to hotel, aviation, hotel, office building, the industry-by-industries such as household.Carpet, as a kind of pavement, has the advantage of its uniqueness, and noise is little, and comfortable foot feeling absorbs dust, attractive in appearance etc., but also has its some shortcomings, for example, be difficult for arranging.In carpet, add insect-proof agent, have efficient protective action, for example all kinds of mosquitoes, flea, ant, cockroach, housefly, acarid, bedbug, flat lice, carpet beetle etc. has obvious avoidance effect, even can drive away house pet parasite with it, makes pet avoid 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 add insect-proof agent for preventing that parasitic existence from being necessary 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, and the mosquito dispersing carpet that a kind of mosquito repelling rate is high is provided.
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, check, packing, finished product.
Above-mentionedly execute bubble, stoving process is, first with foam device foaming, obtain solution, and with citric acid regulate PH to 5, liquid-vapour ratio is 1:40, output foam quality is 25g/L, then execute bubble, 100 grams of foams of every square of carpet, liquid carrying rate 10%, speed: 1.3-1.7m/min, finally push by pressure roller, pressure is: 1.5-2pa, crushes foam to be coated in uniformly carpet surface, then carpet enters four joint oven for drying, bake out temperature 80-130 ℃ under guipure drives.
In above-mentioned foam device, solution used comprises:
Insect-proof agent 50-100g/L
Blowing agent 5g/L
Blowing agent is applied to foam process does the foaming agent of rear arrangement processing, buys producer: chemistry is received in holder, constituent: organic and inorganic salt solution, and containing triethanolamine, alkylbenzene sulfonate, model blowing agent SBL.
Reinforcing agent Nano PU 100g/L is polyurethane BAYPRET Nano PU.
Above-mentioned color fixing process is specially: temperature 128 is spent, and is incubated 3 minutes.
Above-mentioned washing process is specially: after printed carpet color fixation, carry out spray washing, water temperature 35 is spent.
Above-mentioned vacuum dehydration: vacuum pump pressure 3-5Pa, the drugget blanket face after washing siphons away water by vacuum water absorber;
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 Nano PU of certain PH in the preparation technology of carpet, effectively promote the mosquito repelling rate of carpet, and by strict liquid-vapour ratio while controlling foaming, execute the roll extrusion stoving process of quality, addition, liquid carrying rate and the foam of the foam of bubble, the mosquito repelling rate of carpet of the present invention is brought up to more than 98%, there is obvious progress.
The specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described, so that those skilled in the art can better understand the present invention, but therefore do not limit the present invention.
