Description
Technical field
The invention belongs to adhesive technical field, and in particular to a kind of modified corn starch powdery gluing of antibacterial low toxicity
Agent.
Background technology
Adhesive is the blood of China's wood-based panel industry, and China is used as world's Wood-based Panel Production, consumption and foreign trade
The first big country, the annual adhesive for Wood-based Panel Production is calculated over 6,500,000 tons with solid part, and traditional glue kind is mainly
These three " aldehyde system " adhesive made of synthetic resin of urea-formaldehyde resin adhesive, cyanurotriamide modified urea resin and phenolic resin, it is this kind of
The certain cushion rubber burst size of adhesive generally existing, endanger the health of consumer.In order to reduce above-mentioned adhesive release first
The defects of aldehyde, adhesive is prepared as primary raw material using starch.Starch be by many glucose dismiss unit be connected with each other and
Into polysaccharide polymer, it is usually granular, it is not soluble in water, can expand or be swelled in cold water, dry after again be punctured into it is granular,
After starch adds water Heat Gelatinization, although having adhesion, even if concentration or solid content are very low, its viscosity also can be very high, causes
Poor fluidity, easy gel, phenomena such as being not easy to be glued.But after the oxidation of oxidized dose of starch molecule, then with water solubility synthesize macromolecule
Natural polymer is compound or chemical graft after the modified starch that is formed generally there is good performance.
The content of the invention
The invention aims to provide a kind of modified corn starch powdery adhesive of antibacterial low toxicity.
To solve above-mentioned technical purpose, the technical scheme is that：A kind of modified corn starch powdery of antibacterial low toxicity
Adhesive, include the component of following parts by weight：Cornstarch 120-140 parts, montmorillonite 6-10 parts, casein 20-30 parts, acetic acid
It is sodium 22-24 parts, hydrochloric acid 3-5 parts, crosslinking agent 7-9 parts, coupling agent 1-3 parts, defoamer 7-9 parts, compound preservative 25-35 parts, anti-
Microbial inoculum 13-17 parts, urea 18-22 parts, cetyl trimethylammonium bromide 17-25 parts.
Further optimization, the crosslinking agent is zinc oxide.
Further optimization, the coupling agent are silane coupler, titanate coupling agent, aluminate coupling agent, complex compound idol
Join one kind in agent.
Further optimization, the defoamer is tributyl phosphate.
Further optimization, the compound preservative are the molten alkylamine copper of ammonia and copper naphthenate, and its mass percent is 3:1-
5:1。
Further optimization, the antiseptic is nano phase ag_2 o.
A kind of preparation method of the modified corn starch powdery adhesive of antibacterial low toxicity, is comprised the following steps that：
Step 1: montmorillonite addition deionized water high speed is stirred to suspension, it is warming up to slow while stirring at 70-80 DEG C
Cetyl trimethylammonium bromide is added, continues the constant temperature at 70-80 DEG C and stands 5-6h filterings, filter cake is washed with deionized,
Dry organo montmorillonite, it is standby；
Step 2: sodium acetate is dissolved completely in deionized water, adds cornstarch and compound preservative, organically-modified cover take off
Soil, ultrasonic disperse, jitter time 1-2h at room temperature, mixture A is obtained, it is standby；
It is well mixed Step 3: being added to after urea and casein are mixed in mixture A, is filled with nitrogen, heating response, reaction temperature
Spend for 120-130 DEG C, reaction time 0.5-1h, after cooling mixture B, it is standby；
Crosslinking agent, coupling agent and defoamer are added when being warming up to 72-74 DEG C Step 4: mixture B is inserted in reactor, uses salt
Acid regulation pH value is continuously heating to 120-130 DEG C, reacts 5-15min to 7.5-8.5, obtains jelly C, standby；
It is spray-dried Step 5: jelly C is inserted in spray dryer, by centrifuging after drying, jade must be modified
Rice starch powdery adhesive.
Further optimize, the Washing of Filter Cake in the step 1 is repeatedly washing in batches.
Further optimize, the EAT of spray dryer is 180-200 DEG C in the step 5, leaving air temp 90-
100℃。
Further optimize, centrifuged in the step 5 using cyclone separator.
The beneficial effects of the invention are as follows：
First, starch is used as primary raw material, and starch is easily bought and commercially available price is relatively low and pollution-free, belongs to renewable money
Source,；
2nd, when cornstarch prepares adhesive, because its solid content is relatively low, therefore adds montmorillonite and improve the less water of its solid content
Point, while montmorillonite can also effectively block the space of object to be glued, and prevent moisture from entering, accelerate rate of drying；
3rd, casein is a kind of fully biodegradable and reproducible globular protein, wherein 55% amino acid contain carboxyl,
Amino and hydroxyl isopolarity group, it has preferable bonding force, resistance to flatiron, high temperature resistant, especially with good filming performance
And toughness, layer protecting film can be formed when preparing adhesive, improves the high-temperature stability and ageing resistance of adhesive, is improved
Water resistance；
4th, be spray-dried powder processed, obtained powdery adhesive storage period is long, it is not aqueous, be not afraid of jelly, also will not it is mouldy,
Packaging, convenient transportation, add a certain amount of water to stir, and avoid because bringing deformation with liquid glue, tilting, open
The problems such as splitting, the application of powdery year full Resin adhesive can be widely popularized；
In summary, the present invention has the characteristics that bonding strength is high, water-fast, Storage period is long, and primary raw material uses cornstarch, nothing
Formaldehyde adds, and montmorillonite coordinates a variety of effective auxiliary agents, effectively reduce the harm to environment, reduce production cost, carry as filler
The production interests of high enterprise.
