Abstract
The invention discloses an efficient formaldehyde scavenger, which is mainly characterized by comprising a formaldehyde removal factor, a stabilizer, a synergistic agent, a penetrating agent and water. The efficient formaldehyde scavenger can not only capture building materials containing formaldehyde and other chemical substances used in new residences, such as free formaldehyde released from a urea-formaldehyde resin for an artificial plate, but also penetrate into chemical building materials and wood, such as man-made plank, so as to completely remove formaldehyde unreleased from the materials and achieve the goal of long-term, permanent formaldehyde removal. The method provided by the invention has simple process and equipment, no "three waste" pollution and low production cost.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of formaldehyde scavenger.
Technical background
At present, interior decoration needs a large amount of artificial boards, produces these artificial boards and need to make binding agent by the Lauxite take formaldehyde as main component, because Lauxite is unstable, formaldehyde wherein can discharge from ornament materials continuously, the severe contamination room air.Investigation shows that newly-decorated house concentration of formaldehyde generally exceeds standard, and what have reaches more than 40 times.And studies show that in a large number the formaldehyde of low dosage can cause breathing problem, and women's paramenia, neonate's physique reduces, chromosome abnormality, the formaldehyde of high concentration can destroy nerve system of human body, respiratory system, immune system causes the deformity of these systems, causes canceration.Therefore, formaldehyde is " room killer " worthy of the name, human health has been caused very large threat, remove up hill and dale rapidly formaldehyde in the room air become a kind of in the urgent need to.
Existing a lot of formaldehyde scavengers occur on the market now, and from angles of product, existing formaldehyde scavenger and formolite reaction are slower, and elimination efficiency is low, DeGrain; Main component is the formaldehyde scavenger of rudimentary amine, although the formaldehyde removing effect is better, certain toxicity is arranged self, easily to environment, easily secondary pollution is caused in the room in production and use procedure; Simultaneously, existing formaldehyde scavenger also exists product stability poor, and storage period is short, the defective that easily lost efficacy, and formaldehyde scavenger is shorter action time, to making the formaldehyde that occurs after the with medicament helpless; From the production angle, existing formaldehyde scavenger manufacturing equipment and complex process, production cost is high.
Summary of the invention
Purpose of the present invention overcomes the deficiencies in the prior art exactly, provides that a kind of processing performance is good, safety and environmental protection, use is simple, action time is lasting, remove the high formaldehyde scavenger of efficient.
The technical scheme that technical solution problem of the present invention adopts is: high-efficiency formaldehyde scavenging agent is characterized in that mainly being made of by mass percentage following component:
(1) the formaldehyde removing factor: ammoniacal liquor 2%, CARB OXYMETHYL-CHITOSAN 1%, amino acid 3%,
(2) stabilizing agent: 0.3%～1%,
(3) synergist: 0.1～0.3%,
(4) bleeding agent: 1～2%,
(5) surfactant: 1%,
(6) water: 89.7～91.6%,
The pH value of high-efficiency formaldehyde scavenging agent of the present invention is between 7～9, and is nontoxic.
The formaldehyde removing factor in the component of the present invention can react with formaldehyde rapidly, the product of generation excellent stability, nonhazardous, non-secondary pollution; Amino acid adopts the one or more kinds of combined hybrid in glycine, alanine, the leucine to use;
Stabilizing agent refers to light stabilizer, high temperature resistant dose, antioxidant, acidproof alkaline agent, for example vitamin C, EDTA, sodium hydrogensulfite is arranged, and can use separately, also can mix use;
Synergist refers to vegetable oil, polyacrylate, melamine, polyvinyl alcohol, polyvinyl chloride etc., and these compounds can use separately, also can mix use, and the solution of these compounds or emulsion can form fine and close diaphragm behind moisture evaporation;
Bleeding agent adopts one or more compositions of oleic acid, laruyl alcohol, azone, dimethyl sulfoxide (DMSO), menthol, refreshing ketone, it plays the high-effective penetrating effect in product, can be penetrated into the material internals such as chemical building material, timber such as artificial board, thoroughly remove the formaldehyde that does not discharge temporarily in this class material;
Surfactant refers to anion surfactant (stearic acid, neopelex), cationic surfactant (quaternary ammonium compound), zwitterionic surfactant (lecithin, amino acid pattern, betaine type), non-ionic surface active agent (fatty glyceride, aliphatic acid sorb smooth (sapn), polysorbate (tween) is except anion surfactant and cationic surfactant can not be mixed, other can use separately, also can mix use.
Each component of high-efficiency formaldehyde scavenging agent of the present invention all makes easily and purchase obtains, implementation method of the present invention is: in the belt stirrer container, the pure water that adds successively metering, the formaldehyde removing factor, stabilizing agent, synergist, bleeding agent, surfactant, when room temperature, stir 20～50min, after mixing its pH value is transferred to 7～9, then filter with 100 purposes sieve, filter impurity, get final product can after filtrate is left standstill.
Said method prepares new and effective formaldehyde scavenger should be at stirring at room 20～50min, and best mixing time is 30～35min.
The invention has the beneficial effects as follows:
In the component of the present invention the formaldehyde removing factor can be rapidly and formaldehyde react, ammoniacal liquor and formaldehyde reaction product have formamide (HCONH2) and (CH2OHNHCH2OH); The product of amino acid and formaldehyde is hydroxymethyl derivative and methylene imino derivative, and the formaldehyde molecules that a large amount of seizure dissociate in course of reaction; CARB OXYMETHYL-CHITOSAN itself has good biocidal property, catches free formaldehyde molecule and generates stable large molecule methylol chitosamine.Compare with existing product, product of the present invention has following advantage:
High efficiency: the present invention adopts the special powerful formaldehyde scavenger factor, can be fast up hill and dale with formolite reaction, reach the purpose of removing formaldehyde,, nonhazardous stable with the product behind the formolite reaction, non-secondary pollution.
Safety and Environmental Protection: the used equal safety non-toxic of raw material, product and the formolite reaction afterproduct of the present invention is nontoxic, harmless, and each group partition inter-capacitive is good, and chemical reaction does not occur each other, and storge quality is good.
Simplicity: formaldehyde scavenger of the present invention is easy to use simple, and only need be sprayed on the formaldehyde emission place can obtain to catch effect, at normal temperatures and pressures, as long as Formaldehyde Exposed can react.
Persistence: can form fine and close diaphragm at plate surface after formaldehyde scavenger of the present invention uses, action time is more permanent.
Inexpensive property: formaldehyde scavenger generation equipment of the present invention and generating process are very simple, and production is carried out under the normal temperature and pressure again, and production cost is low.
Application is strong: it can not only catch New Dwelling, and all contain the building materials of the chemical substances such as formaldehyde, such as artificial board with the free formaldehyde that discharges in the Lauxite, and can be penetrated into the material internals such as chemical building material, timber such as artificial board, thoroughly remove the formaldehyde that does not discharge temporarily in this class material, reach the purpose of for a long time, forever removing formaldehyde.
The specific embodiment:
The formaldehyde scavenger effect is measured by the drier method among the Chinese Industrial Standards (CIS) GB 18580-2001 " formaldehyde discharges and limits the quantity of in indoor decorating and refurnishing materials-wood-based plate and the goods thereof ".
