Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of diatom coating of plate.
Background technique
Coating, in the entitled paint of Chinese tradition.So-called coating be coated in the body surface being protected or decorated, and
The continuous film of firm attachment can be formed with coated article, usually based on resin or oil or lotion, add or do not add face
Material, filler add corresponding additive, the thick liquid being formulated with organic solvent or water.Coating is common as plate surface layer
Coating material, service performance for plate and has great importance to the protection of plate.Plate is worked as furniture finishing
In, house increasingly be unable to do without finishing, and owns " problem house " all more or less there is the pollution of benzene homologues, these benzene
It is the release that object is mainly derived from organic matter in indoor decorating and refurnishing materials.
CN103923536A reports a kind of preparation method of ordor removing ecology damping antibacterial inner wall paint, is formulated main component
Contain lotion, titanium dioxide, diatomite, nano-titanium dioxide etc.；CN103741545A reports a kind of antibacterial diatomite base coating
And its preparation method and application, it is both that containing diatomite coating is prepared by physical mixed method.And chemical method is a kind of valence
Lattice are cheap, device simple, the effective ways for preparing multifunctional composite, are more and more paid attention to.Coconut husk charcoal is current
A kind of active carbon being most widely used, mainly uses good coconut husk for raw material, by multiple rotary calcining, scientific allocation,
It refines.The hole of coconut husk charcoal is flourishing, and adsorption capacity effectiveness in active carbon series of products is most it will be evident that in addition carbon body is strong
Degree is high, and the saturation period is long, is known as " fine work in carbon " in the industry.Why coconut husk charcoal has such effect, mostlys come from its
Production technology, wherein pyrolysis is a mostly important link.High temperature pyrolysis promotes coconut husk reconstruction and generation self-activation anti-
It answers, prepares the very flourishing active carbon of micropore, technical process does not add any activated gas or chemical reagent, innovated one
The clean method for preparing of kind microporous activated carbon.Under certain heating rate, firstly, system is warming up to 400 DEG C, coconut husk natural tissues
Pyrolysis releases a large amount of pyrolysis gas, vapor, carbon dioxide and carbon monoxide is mainly contained in gas, in addition sealing in reactor
Air and raw material absorption oxygen, form admixture activation atmosphere, and as temperature is increased in closed reactor expert at one
Constant-pressure；Secondly, continuing to increase temperature to 800 DEG C, aromatization occurs for organic matter in coconut husk, continues to generate gas, tissue
Reconstruction.However, the coating formed is since hole is by other if coconut husk charcoal is added in coating directly as additive
Filler blocking etc. reasons so that its remove formaldehyde effect be not it is very ideal, even zero.
Summary of the invention
The present invention proposes a kind of diatom coating of plate, which removes formaldehyde efficiency, persistently.
The technical scheme of the present invention is realized as follows:
A kind of diatom coating of plate, according to the number of parts by weight, including following components:
55~75 parts of water soluble acrylic resin, 25~35 parts of amino resins, modified 25~35 parts of coconut husk powdered carbon, peppermint mention
Take 6~12 parts of liquid, 3~6 parts of dispersing agent, 0.6~1.8 part of thickener, 25~35 parts of diatomite and 40~60 parts of water；Wherein, institute
Stating peppermint extracting solution is to carry out subcritical abstraction acquisition using dried peppermint leaf as raw material, diatomite needs are previously added containing 1~
Drying process is drained after the aqueous solution soaking processing of 3wt% zinc ricinate.
Preferably, the modified coconut husk powdered carbon is mainly prepared by coconut husk powdered carbon, citric acid and cyclodextrin, including following
Step:
1) coconut husk powdered carbon is added to the water carry out ultrasonic disperse, then adds lemon 2~3h of acid soak, is suspended
Liquid；
2) the suspension heating water bath of step 1) is added into cyclodextrin to 55~75 DEG C, stirs and evenly mixs 40~60min,
Then it dries.
Preferably, the mass ratio of the coconut husk powdered carbon and the citric acid is 45~55:1, the coconut husk powdered carbon and institute
The mass ratio for stating cyclodextrin is 10~16:1.
Preferably, the dispersing agent is dispersing agent 5040.
Preferably, the thickener is carboxymethyl cellulose or hydroxyethyl cellulose.
Preferably, the diatomite is diatomite or diatomite.
The preparation method of the diatom coating of plate of the present invention: said components are uniformly mixed according to the proportion.
Beneficial effects of the present invention:
1) the modification coconut husk powdered carbon being mainly prepared by coconut husk powdered carbon, citric acid and cyclodextrin is added in the present invention, led to
Cross cyclodextrin and citric acid prevents from applying to coconut husk carbon dust progress surface modification treatment so that its pore structure is effectively protected
Blocking of the diatomite to hole in material can allow modified coconut husk powdered carbon to give full play to its formaldehyde adsorption effect.In addition, peppermint raw material
The wild dried peppermint leaf come completely, natural health.Peppermint extracting solution has the effect of natural purifying formaldehyde, and smell is pure and fresh, Ke Yigeng
Add and rapidly removes removing and harmful gas and peculiar smell.
2) diatomite is a kind of biogenic siliceous sedimentary rock, is that the remains of the Diatomeae grown in ocean or lake exist
Subaqueous deposit, a kind of nonmetallic mineral gradually formed through natural environment effect.There are many micropores inside diatomite, has one
Fixed chemical activity, average grain diameter is less than 2 μm, theoretical specific surface area about (40~50) m2/g.Because of its unique structure feature, make
Obtain the diatomite physical property strong with fine and smooth, loose, light, porous, water imbibition and permeability.Diatomite in coating of the present invention needs
Drying process is drained after being previously added the aqueous solution soaking processing containing 1~3wt% zinc ricinate, so that its inside is micro-
Hole is more easier to absorb the pernicious gases such as decomposing formaldehyde.
