Abstract
The invention provides a method for preparing an environment-friendly floor board underlayer. The underlayer is prepared by firmly covering a composite catalyst material on a flaky adsorbing filter material. Only by evenly paving the environment-friendly floor board underlayer under a floor board so that the back side of the floor board is contacted with the environment-friendly floor board underlayer closely, the environment-friendly floor board underlayer can clear off harmful gases such as formaldehyde, benzene and the like and off flavor generated and released by the floor board and auxiliary materials, prevent damp and humidify, reject milden and rot, kill and inhibit bacteria, expel insects and prevent moths, increase vitamin-anions and far infrared rays in the air, and reduce the harm of dust mites and respirable particles. The environment-friendly floor board underlayer is advantageous to keep body healthy, prevent floor board form polluting, and prolong the service life of the floor board. The use is simple and convenient without professional constructions, the purification lasts without rebound, and the effect is fast and thorough; and experimental detections show that the degradation rate of the formaldehyde within 24 hours reaches 99 percent, the degradation rate of the benzene within 24 hours reaches 92 percent, the antibacterial rate is 99 percent, the mold prevention is at a zero level, the insect expelling rate is 92.8 percent, and the acute property is is actually at a nontoxic level by oral toxicity test.
Description
Affiliated technical field
The present invention relates to the preparation method of a kind of environment-friendly type floor bed course, specifically, relate to a kind of preparation method with environment-friendly type floor bed course of removing pernicious gas, antibacterial and mouldproof, damping protection against the tide, expelling worms and preventing moth function.
Background technology
China's wood flooring industry originates from early 1980s.Raising day by day along with the flourish of China's economy and resident living level, outstanding advantages such as wood flooring is comfortable with its feel, warm, cool in summer and warm in winter naturally, noble elegance, become the preferred material of people's ground decoration, its market demand is ascendant trend linearly.China has ranked among the ranks of world wood flooring big country, and the esidential building floor amount of mating formation has accounted for about 50% of floor file ornament materials.Enter 2007, the annual area of mating formation of selling in national floor is estimated up to 4.49 hundred million square meters.
People are when selecting to mat formation the floor, often be primarily focused on the general issues such as wear-resisting revolution, specification style, designs and varieties, seeds title, quality technology, and solve the indoor environmental pollution potential problem that auxilliary material accumulation such as floor board and floor glue produces for installing, safeguard and how taking precautions against, but usually ignore.Hardly realize, the underfloor that seems ordinary, crisis-ridden in fact.
Present modal floor paving method has suspension method, keel method and gluing legal, and wherein preceding two kinds of methods utilization at most.After mating formation in the floor, between floor and ground, can form a small space of usually being ignored, forgeing by the people, here just premises of paramount importance, the most hidden, maximum area, also be the indoor environmental pollution source of the most difficult improvement.This space clustering the liquid that oozes from the slit, floor, beverage, swill and dust, hair, scurf etc., because moisture is assembled, circulation of air is poor, be in vexed wet condition for a long time and be difficult for improvement, underfloor has become domestic hygiene dead angle all the year round, assemble formaldehyde and growing all kinds of assorted bacterium, germ, mould, cockroach, insect and worm's ovums such as ant, pet lice flea, the dirt mite, pathogen etc. are various poisonous, harmful, carcinogen, constantly accumulation, slowly discharge, cause the floor to damage by worms, the distortion of making moist, mouldy becoming mildewed, rotten, formaldehyde peculiar smell etc., health in serious threat, and influences floor application life.
In addition, although brand floor on the market is at the burst size of methanal of making great efforts to reduce product at present, zero absolute pollution floor is non-existent, discharges even floor up to standard also has formaldehyde, and, be detrimental to health owing to area causes the pollution accumulation stack greatly.Common floor burst size of methanal standard be meant the floor external surface burst size of methanal but not ground intralamellar part burst size of methanal, the content of formaldehyde of ground intralamellar part is higher, owing to will repeatedly cut the floor in the pavement process of floor to adapt to the real size needs, therefore increase the actual burst size of ground intralamellar part formaldehyde greatly.Formaldehyde discharges and exceeds more than usual more than 30% under hot and humid environment, and lasting release can reach 3-15.Especially to summer or heat supply in winter (special geothermal heating system) phase, the burst size of methanal on floor and rate of release can significantly increase.Auxilliary materials such as a large amount of underproof profiles, ground cushion, glue more become the important hidden danger that formaldehyde discharges.National health, construction and environmental administration once carried out a flooring ornament materials selective examination, found that the material with toxic gas pollution accounts for more than 60%, and these ornament materials can volatilize the volatile organic compound of kind more than 300.
Formaldehyde is than high toxic material, preferentially controls on the list formaldehyde at China's toxic chemical and is in second.Being the allergen of generally acknowledging, also is one of potential strong mutagen.On June 5th, 2004, the World Health Organization issued bulletin No. 153, announced that formaldehyde is strong carcinogenic substance.International cancer research institution (IARC) studies show that formaldehyde not only can cause CARCINOMA OF THE NASAL CAVITY and nasal sinus cancer, and expression can leukemogenesis on evidence.Formaldehyde in indoor air concentration reaches 0.06-0.07mg/m
3The time, slight asthma will take place in children; Reach 0.1mg/m
3The time, peculiar smell and sense of discomfort are just arranged; Reach 0.5mg/m
3The time, can stimulate eyes, cause and shed tears; Reach 0.6mg/m
3, can cause throat discomfort or pain; When concentration is higher, can introduce n and V, it is uncomfortable in chest to cough, asthma even pulmonary edema; Reach 30mg/m
3The time, meeting is the causing death immediately.Long-term contact low dosage formaldehyde can cause chronic respiratory disease, causes nasopharyngeal carcinoma, colon cancer, brain tumor, pregnancy syndrome, causes neonatal chromosome disorder, leukaemia.
Expansion or contraction joints must be reserved in the floor in pavement process, provide passage for the pollution of underfloor is discharged into space outerpace, wooden floor especially, and days are of a specified duration more, and the slit is big more.People are often movable on the floor, thereby make " bellows effect " between subtle floor of the stressed generation in floor and ground, cause a large amount of contaminated gas of underfloor and contaminant stream to be led to above the floor, cause indoor air to pollute.Floor and the pollution relevant with the floor discharge and begin to extend from ground, and generally accumulate near the face of land, also have the part pollution can be deposited near the face of land in the pollution that simultaneously indoor other article produce, infant's harm of playing to liking creeping on the floor is bigger.
For solving the inferior problem on above-mentioned floor, reduce " floor pollutions ", prolong floor application life, people once thought every possible means:
(1) at the auxilliary installed floor moistureproof cushion of underfloor
The flexible foaming plastic layer that this normally a kind of 3-5mm is thick is assisted between floor and ground, plays protection against the tide, levelling and improves the effect of feel.Because it is a plastic layer, the moisture that can cut off ground returns the bottom surface, floor, but also can only cut off between it and the bottom surface, floor for liquid such as oozing the water for cleaning that gets off, beverage from floor seam, thereby these liquid can only be absorbed by bottom surface, floor and floor side, cause the floor make moist easilier, mouldy, become mildewed.
(2) underfloor is put active carbon or bamboo charcoal
Active carbon and bamboo fibre have porosity and adsorptivity, have good effect for the absorption of pernicious gas.But it is easily saturated, no long-lasting.To no longer work after saturated in case adsorb, and the dusty gas of absorption might be discharged once more.Their saturated time limit is generally about two weeks, and the formaldehyde on floor discharges and reaches as high as more than ten years, and it is anxious therefore just to separate pollution control for the moment.Simultaneously, can not be applied to the exigent keelless floor type of ground flat degree.
(3) underfloor spreads Chinese prickly ash or camphorwood piece
Be that a kind of self-deceiving smell hides, do not reach real improvement for formaldehyde etc. and pollute purpose, sterilization, expelling parasite are had certain effect.
(4), underfloor spreads insecticide
Insecticide itself has toxicity and side effect, though for insect pest effect is arranged, human body is also had harmfulness, especially for pregnant woman lower for the resistance, baby etc.Particularly when this similar drug flew away above the floor along the slit, its harmfulness was more serious.
(5), underfloor is put paraffin
This is for the drying that keeps the floor and prevent that moisture from having distributed certain effect, but does not have effect substantially for pollution control.
(6), floor surface waxing
This is helpful for the maintenance floor surface, to delaying distributing of floor surface pernicious gas certain effect is arranged also simultaneously, but does not then have any effect for floor bottoms and pollution control that the side discharged.
Popularization and the seriousness that pollutes on the floor are paid attention to by expert and R﹠D institution already, but almost there is not real feasibility solution for many years, especially for the floor pollution control of mating formation after finishing, be that construction means is loaded down with trivial details, cost is too high unrealistic, or be exactly the humble market demand that is not suitable for of effect.Because floor dismounting difficulty, in case, be difficult to administer just difficult cleaning after installing as not prevention in advance, will become hidden danger all the year round.
So need to develop, develop and a kind ofly before install on the floor, use, be laid on underfloor, have pernicious gases such as the formaldehyde of removing, benzene, ammonia, and the novel floor bed course with functions such as antibacterial and mouldproof, damping protection against the tide, expelling worms and preventing moth, minimizing dirt mite and pellet harm.
