Description
Technical field
The present invention relates to a kind of high density fiberboard, particularly a kind of high density fiberboard and its system with antibacterial functions
Make technique.
Background technology
High density fiberboard is one kind of fiberboard, and its density is typically generally 10-40mm in 800kg/m3, thickness.It is high
Density fiber board is widely used in sound equipment, consolidated floor, interior decoration wallboard etc., is important industrial building materials.And
Nowadays with the improvement of living standards, functional requirement of the people to high density fiberboard also improves therewith.Outdoor Air Quality
Decline, the raising for more causing people to require indoor environment, the method for constantly seeking to reduce indoor bacteria.Nowadays, there is antibacterial
Also research is seldom so far for the high density fiberboard of performance.The high density fiberboard overwhelming majority remains free formaldehyde on the market, right
There is very big harm in health, therefore be also required to reduce the content of formaldehyde, there is provided the high density fiberboard of environment-friendly type.
The content of the invention
The invention aims to solve above-mentioned the deficiencies in the prior art a kind of environment-friendly type is provided, there is anti-microbial property
A kind of high density fiberboard and its manufacturing process with antibacterial functions.
To achieve these goals, a kind of high density fiberboard with antibacterial functions designed by the present invention, including fibre
Peacekeeping adhesive, the parts by weight of the fiber and adhesive are fiber 55-65 parts, and adhesive is 35-45 parts；The adhesive
Including distribute in parts by weight starch 30-40 parts, butyl acrylate 15-25 parts, soybean glue 5-15 parts, deionized water 5-10
Part, maleic acid 5-10 parts, sodium dihydrogen phosphate 2-6 parts, polyvinyl alcohol 3-7 parts, modified antiseptic 5-10 parts, magnesia 2-4
It is part, coupling agent 1-3 parts, catalyst 5-8 parts, defoamer 1-2 parts, plasticizer 0.5-1.5 parts, tackifier 0.8-1.5 parts, anti-oxidant
Agent 0.2-1 parts；Wherein described modified antiseptic includes the citric acid 5-10 part, agar powder 5-10 parts, oxygen distributed in parts by weight
Change silver-colored 20-30 parts, nano zine oxide 5-15 parts, hydantoins 10-20 parts, ammonium persulfate 8-12 points, polyethylene glycol 3-9 parts, go
Ionized water 10-16 parts, acetic acid 2-5 parts.The starch is farina, cornstarch, tapioca, water caltrop starch, wheat
Any one in starch, green starch.The fiber is waste and old wood, branch, crotch, stalk by crushing, removing the peel, de-
The fiber being worth after silicon, boiling defibrator process, drying.The coupling agent is aluminate coupling agent；Catalyst is cobaltmolybdate catalyst；Defoaming
Agent is organic silicon defoamer；Plasticizer is ATBC；Tackifier are polymethacrylates.
A kind of manufacturing process of the high density fiberboard with antibacterial functions is as follows：
The first step：Modified antiseptic is prepared, first 5-10 part citric acids are dissolved in 10-16 part deionized waters；Sequentially add
10-20 parts hydantoins, 8-12 divide ammonium persulfate and 3-9 part polyethylene glycol, and bath temperature is to be heated and with 60-80r/ at 85 DEG C
Min rotating speed stirring 30-45min；Then 5-10 parts agar powder, 20-30 parts silver oxide, 5-15 parts nano zine oxide and vinegar are added
Sour 2-5 parts, heated at being 95 DEG C in bath temperature and 2-3h is stirred with 80-100r/min rotating speed；Placed after being cooled to room temperature
24h is stand-by；
Second step：Adhesive is prepared, 5-10 parts deionized water, 30-40 part starch are uniformly mixed and made into pulpous state；Add 15-
25 parts of butyl acrylates, 5-15 parts soybean glue, 1-3 parts coupling agent, 3-7 parts polyvinyl alcohol and 5-8 part catalyst, it is in temperature
52-58 DEG C is to stir 3-4h under 50-70r/min with mixing speed；Then 5-10 parts maleic acid is sequentially added, 5-10 parts change
Property antiseptic, 2-4 parts magnesia, 2-6 parts sodium dihydrogen phosphate and 0.2-1 part antioxidants, temperature be 56-64 DEG C and stirring speed
Spend to stir 2-2.5h under 80-90r/min；Then 0.5-1.5 parts plasticizer and 0.8-1.5 part tackifier are added, are warming up to 76-
0.5-1h is stirred with 30-50r/min at 82 DEG C；1-2 part defoamers are eventually adding, are cooled at 30-40 DEG C with 40-60r/min
Mixing speed stirring 0.5-1h, finally give adhesive；
3rd step：The high density fiberboard with antibacterial functions is prepared, by waste and old wood, branch, crotch or stalk from conventional
Means are crushed, skin, desiliconization, boiling defibrator process, drying, obtain required fiber；By 55-65 parts fiber and 35-45 part adhesives
Input is stirred into mixing plant, is taken out and is poured into template after stirring, cold compression mould, fully solid at 35-40 DEG C of room temperature
Change, you can obtain the high density fiberboard with antibacterial functions.
Wherein, when preparing adhesive, the starch of use belongs to biomaterial, and price advantage is obvious, wide material sources, green
Environmental protection, belong to the rational exploitation and utilization of renewable agricultural resource, it is possible to increase the added value of agricultural product.Butyl acrylate is to prepare
The soft monomer of adhesive.Magnesia has certain anti-flammability, and can be formed in integral system scleroid waterproof, impermeable
The lattice structure of gas, the fiber grain in fiberboard can closely be wrapped up so that fiber grain substantially with the external world
Air, aqueous phase is every anti-oxidation, corrosion so that fiberboard has certain water resistance, and it is magnesia that sodium dihydrogen phosphate, which is exactly,
Certain sour environment is provided, promotes the compactness of its lattice structure.Polyvinyl alcohol is a kind of auxiliary agent.
Wherein, it is three-aldehyde glue that domestic market wood-based plate is most commonly used, i.e. urea-formaldehyde glue, phenol glue, melamine aldehyde
Glue.These three glue are all the main sources of artificial board formaldehyde content overproof.It is common that soybean protein glue is totally different from the market
Three-aldehyde glue, raw materials are entirely free of the harmful substances such as formaldehyde and phenol, the formaldehyde for solving adhesive from raw material source
Harm problem.Soybean glue be using plant resources soybean meal as raw material, with can be prepared under the mixed cooperation of deionized water
Into the adhesive of environmental type.
Wherein, antiseptic is using the modified antiseptic of self-control, wherein silver oxide and nano zine oxide be respectively provided with good sterilizing,
Anti-microbial property；Hydantoins is a kind of good antiseptic, in the presence of ammonium persulfate, can cause second after being mixed into adhesive
Interior uride is in whipping process in smooth grafting and fiber, and so as to improve the antibiotic property of fiber, polyethylene glycol is modified as preparation
Catalyst in antiseptic course of reaction so that it is complete that reaction can shorten time progress.Citric acid and agar powder are combined into it
Middle silver oxide and nano zine oxide provide good graft structure.
A kind of high density fiberboard and its manufacturing process with antibacterial functions that the present invention obtains, it has the technical effect that：
Adhesive major ingredient used is starch, belongs to biological material, and cheap, wide material sources are green, belong to renewable agricultural
The reasonable development and utilization of resource, the added value of agricultural product can be improved；Secondly, during adhesive is prepared, do not add
It can produce or the material containing formaldehyde, to human body fanout free region, antiseptic is added in adhesive so as to improve high-density fiber
The anti-microbial property of plate.
