Description
Technical field
The invention belongs to field of high polymer material modification, be related to a kind of compound organic mould inhibitor of thermolysis-resistant load formula,
Composite material and electric control element shell.
Background technique
Plastics itself from the point of view of simple are much that bacteria can be prevented from growing and mould, and reason is attributed to main structure by carbon
Hydrogen long-chain is constituted.
But this, which does not represent conventional plastic products, to be infected by bacterium and mould.
The use of plastics is usually along with modification.By adding various auxiliary agents so that plastics itself have some particularity
Can, or facilitate plastics itself machine-shaping.And in above-mentioned auxiliary agent as fatty acid plasticizer, lecithin dispersing agent, lubricant,
Antioxidant etc. can supply nutrients for the growth of bacterium mould, so that plastic products become high-quality culture medium.Its
Secondary, it also can be thin that for plastic products in manufacture, storage, transport and use process, surface, which can gather the substances such as dust, greasy dirt,
The flourish of bacterium mould provides adequate condition.When reaching certain suitable degree along with ambient temperature and humidity, bacterium mould it is numerous
Growing almost becomes inevitable with fast-growth, and bacterium change and mildew will occur for plastic products at this time.
Usually the antibacterial of plastics and mould proof merging are studied in the prior art, such as chemistry institute engineering plastics state of the Chinese Academy of Sciences
The third place sunshine and Li Bizhong of family's Engineering Research Center, they have delivered " the preparation and property of antibacterial and mouldproof master batch and its plastics with regard to this
Can study " text.
Although we pass through the study found that antibacterial and it is mould proof can be communicated substantially in auxiliary agent using upper, with regard to plastic basis material
Occurrence condition, principle and the damage mode and degree that bacterium becomes or goes mouldy, it is entirely different.
The bacteria breed of plastics and the objective condition difference met needed for mould growth first is very big.Such as long-term manpower touching
It touches or moves the plastic part bacterium easy to breed of touching but will not usually go mouldy, and long inactivity is in dark wet environment
Plastic part mould easy to breed but be usually less susceptible to occur bacterium become.
Visit to find out its cause, essentially consist in that bacterium is different from the modes of reproduction of mould and plastic products are infected with germs with it is mould
The approach of bacterium is different.General mould usually need to be in 26~32 DEG C in temperature, while in the dual situation of humidity >=85%
It can breed and grow (humidity needed for rare is >=65%), it is seen that is extremely harsh to environmental requirement；And bacterium is then to each of environment
Kind Parameters variation is not very sensitive compared to for mould, while reproduction speed is very fast, and cenobium is more stable.Bacterium, which usually passes through, to be connect
Touching is propagated, and mould is mostly air borne.Excessively frequent touch is easier to cause bacteria breed, and has inhibition to make mould
With vice versa.
Therefore it should be discussed respectively with regard to the above problem in different application field and use environment.But the prior art is not
For concrete application field, use environment and the service condition of plastic part, the selection progress to antibacterial mildew inhibitor is unfolded in detail
Thin research.
Our known antibacterial mildew inhibitors are broadly divided into natural agent, inorganic dose, organic agent and complexing agent.
The advantages of organic mould inhibitor is: sterilizing ability is strong, is mainly reflected in initial sterilizing ability and sterilization is imitated.
But the shortcomings that organic mould inhibitor, is also fairly obvious: 1, toxicity safety；2, biology is also easy to produce drug resistance；3, the service life is short.
The thirdly factor mainly to restrict organic mould inhibitor application at present especially therein.Organic mould inhibitor heat resistance is bad, meets
Unstable under plastics high temperature and pressure high shear processing conditions to light and heat etc. are more volatile or oxygenolysis, effect reduces obvious
Or even it is entirely ineffective, it is also possible to generate harmful by-products.In the prior art, in order to overcome organic mould inhibitor heat-resisting bad
And the problem of processing loss, there are two types of the technical solutions of use: the first is the initial additive amount for increasing organic mould inhibitor at double,
With this come the consumption caused by undesirable element that liquidates.But this way not only increases cost input, can also make plastics performance itself
It is a greater impact, has facilitation instead to the generation of harmful by-products.Be for second by inorganic fungicid with it is organic mould proof
Agent compounds to form the inorganic organic mould inhibitor of Compositional type, but simple compounding is only to keep considering in certain effect, instead
The common issue of inorganic and organic mould inhibitor can be brought.
The installation site of electric control element is very extensive, wherein just including the installation site of numerous high humidity environments, such as underground
Room, cellar, underground parking, natatorium, bathroom clothes-changing chamber, constant temperature high humidity workshop, offshore work platform are electrical at air port
Mould group etc..In above-mentioned environment, electric control element plastic shell easily goes mouldy in the case where not adding mould inhibitor, mould
Change can bring following problems: electric property is changed, mycelia infringement causes structure to destroy and lead to mechanical properties decrease, water imbibition
Increase, plastic part rhegma and cause internal exposed to keep its easy to aging etc..Each mould proof auxiliary agent in the prior art, when different
Have that additive amount is few, heat-resisting degrading resistance property is good, high humidity is mould proof and long-term mould proof.
Summary of the invention
The present invention is mainly for following three technical problems of solution:
1, the necessary additive amount of mould inhibitor is excessive.
2, heat-resisting degrading resistance property is poor.
3, long-term continuous high humidity environment anti-mold effect is poor.
In order to solve the above-mentioned technical problems, the present invention provides a kind of thermolysis-resistant compound organic mould inhibitor of load formula, by with
Lower component is constituted:
Adsorbent, the adsorbent are porous adsorbent, and the specific surface area of the porous adsorbent is 250~1200m2/
G, heat of adsorption are 0.8~76kJ/mol, and regeneration temperature is 180 DEG C~300 DEG C；And
Adsorbate, the adsorbate is the compound organic mould inhibitor being attracted on the porous adsorbent, described compound
Organic mould inhibitor includes triazole bactericidal agent.
Porous adsorbent reduces the surface free energy of itself in adsorption process, this portion of energy being lowered is with heat
Form distribute, and when it reuptakes heat, opposite desorption process can also occur.Therefore from presentation,
Adsorption process is exothermic process, is desorbed as endothermic process.
The present invention exactly utilizes above-mentioned principle, to achieve the purpose that improve organic resistance to temp effect of mould inhibitor.Of the invention
In technical solution, the applying heat that the compound organic mould inhibitor of load formula is subject in the hot environment of processing and forming has very big
A part is used for the desorption between porous adsorbent and compound organic mould inhibitor, and remainder is just really by compound organic mould proof
Agent is carried, therefore greatly reduces organic mould inhibitor in the middle thermal losses of thermal environment, or improve in equal loss most
Height allows processing temperature.Process especially higher in some temperature and that the time is shorter is more applicable.
Moreover, the sustained release that formula structure additionally aids compound organic mould inhibitor is carried, the long-term mould proof of resin product is reached
Effect.Although effective mould proof process of resin product usually only occurs on its surface, organic mould inhibitor has certain
Consumption characteristics, the consumption characteristics are mainly reflected in caused by the mould proof active consumption of Continuous sterilization and environment and passively consume.With
The passage of time, at surface organic mould inhibitor concentration decline, when its concentration be lower than threshold value when, bacterium become and mildew the phenomenon that
Positive it will occur.Porous adsorbent facilitate minimal amount of organic mould inhibitor is evenly dispersed in resin, from inside to outside
The supplement that the organic mould inhibitor slowly migrated is just used as surface to consume, prevents organic mould inhibitor from causing since migration velocity is too fast
Bulk deposition is damaged in resin article surface by the passive consumption of environment；The mode of action of slow release simultaneously, can make
The supplement process of organic mould inhibitor is more controllable, by selecting different types of porous adsorbent, is suitble to corresponding difference to reach
The use environment of mould proof intensity.
For porous adsorbent select should follow the rule referred in above-mentioned technical proposal: i.e. specific surface area is 250
~1200m2/ g, heat of adsorption are 0.8~40kJ/mol, and regeneration temperature is 180 DEG C~300 DEG C.
Specific surface area refers to the gross area possessed by unit mass material, in the ideal situation, the bigger absorption of specific surface area
It measures bigger.Wherein adsorbent is divided into non-hole adsorbent and porous adsorbent according to the difference of structure.Non- hole adsorbent only has
External surface area, and porous adsorbent that the present invention refers to while there is external surface area and internal surface area.It can be seen that porous absorption
Agent and non-hole adsorbent are slightly different in the effect to adsorbate, and non-hole adsorbent is almost complete suction-operated, and more
Hole adsorbent also includes certain effect to be plugged and fixed.
On the other hand, the porous adsorbent adsorption effect of too small specific surface area is poor, and crosses the porous suction of high-specific surface area
The size that the effect of attached dose of absorption is adsorbed matter seriously restricts, and cannot pass through porous adsorbent when the size of adsorbate is larger
Hole when, internal surface area can not be fully utilized, and but will reduce practical absorption of the porous adsorbent relative to this kind of adsorbate
Ability.Therefore in the technical scheme, the specific surface area for defining porous adsorbent is 250~1200m2/ g, more preferably for
550~950m2/ g, more preferably 800~900m2/g。
Too low heat of adsorption and regeneration temperature is too small to the protective effect power of mould inhibitor organic in processing and forming, and excessively high
Heat of adsorption and regeneration temperature larger obstruction is caused to the surface migration of later period organic mould inhibitor.It need to be according to specific application scenarios
To be specifically chosen to heat of adsorption and regeneration temperature.More preferred heat of adsorption is 51~75kJ/mol, regeneration temperature 240
DEG C~295 DEG C.
In addition, permanently effective mould proof characteristic, also related with the single time duration of adverse circumstances locating for product simultaneously,
I.e. the single duration is longer, the migration velocity of organic mould inhibitor should be required faster, vice versa.Side provided by the present invention
Case, the long-time service being suitble under high humidity thermophilic environment, especially single duration are longer, more particularly medium and small plastic system
Above part, such as all kinds of electric control element shells.The so-called single duration refers to that ambient temperature and humidity reaches fungus growth and is suitble to count
The time kept after value.
Preferably, compound organic mould inhibitor is made of triazole bactericidal agent and isothiazolinone compound.Into one
Step is preferred, and the triazole bactericidal agent is triazolone, Tebuconazole, fine bacterium azoles, propiconazole, Flusilazole, glyoxalin, phenyl ether methyl cyclic

The sum of both Tebuconazoles weight is 2:1~1:75 with the hexaconazole weight ratio.
It finds after study, it is anti-that the above-mentioned organic mould inhibitor for belonging to triazole bactericidal agent can obtain good sterilization

When being applied to some special circumstances, as when resin base material germ contamination probability is small, local environment humidity is high, own azoles
Alcohol is more excellent relative to the practical long-term mould proof needs of Tebuconazole satisfaction.And water solubility of the Tebuconazole at 20 DEG C is
32mg/L will be apparently higher than the 0.018mg/L of hexaconazole, when preparing high humidity mould inhibitor, for some preparation methods, suitably mention
High hexaconazole content can obviously reduce preparation difficulty, improve yield and product quality, therefore recommend Tebuconazole and hexaconazole
Weight ratio is between 1:1~1:150, and 1:100~1:120 is more preferred scheme.It certainly also can be with appropriate according to tree
Aliphatic radical material is adjusted the content of Tebuconazole by bacterial infestation risk height.

Mould plays the role of inhibiting dissipation.It has been surprisingly found that after study, there are synergistic effects with hexaconazole for isothiazolinone compound
Relationship, especially in the presence of Tebuconazole, more particularly effect is more preferable with Tebuconazole equivalent, wherein
The chloro- 2- n-octyl -3- isothiazolinone effect of 4,5- bis- in isothiazolinone compound is best.
