Description
Technical Field
The invention belongs to the technical field of adhesives, and particularly relates to a hot-melt strong-performance adhesive sticker which is used for catching harmful organisms such as mice, cockroaches, flies, mosquitoes and the like.
Background
The four pests refer to mice, flies, cockroaches and mosquitoes which have strong viability and fertility, are widely distributed all over the world and are difficult to remove, thereby bringing great trouble to human life. Four pests as disease-vector organisms, i.e. pests that can transmit diseases, can transmit some infectious diseases to humans: such as dengue fever, encephalitis, malaria, typhoid fever, hemorrhagic fever, and the like. Therefore, the task of controlling four pests is very slow.
The existing four-pest control method is multiple, taking a mouse as an example, the method generally comprises raticide, a special mouse trapping tool and biological control, and mouse glue is used as the special mouse trapping tool. The traditional mouse sticking board has good physical catching effect of mouse glue, but is difficult to achieve ideal conditions for various temperature environments and individual differences of mice around the world. In addition, the rat glue produced at present at home mainly adopts hot-melt pressure-sensitive adhesive, cannot well adapt to the condition change of high and low temperatures, cannot resist high temperature, has poor anti-sagging property, and cannot meet the requirement of ultra-long-distance transportation, thereby losing the foreign market. For example, the Chinese patent No. 201310107390.8 discloses a hot-melt mouse glue and a preparation method thereof, and the mouse glue is mainly used for catching mice. The hot-melt rat glue consists of, by weight, 35-45% of petroleum resin, 5-15% of styrene butadiene rubber, 5-15% of natural rubber, 10-20% of polyisobutylene, 20-30% of naphthenic oil, 1-2% of an antioxidant and 1-2% of a spice. The mouse glue of the technical scheme has the advantages that the performance is obviously reduced at the temperature of-10 ℃, the mouse sticking effect is poor, the anti-sagging property at the temperature of 60 ℃ is poor, and the ultra-long distance transportation such as sea transportation cannot be met, so that the economic benefit is influenced.
Therefore, in the field of four-pest control, the market urgently needs a strong high-performance adhesive sticker which has low processing temperature, is easy to spray and produce, can adapt to a large temperature range, has strong anti-sagging property and can resist high temperature (below 75 ℃) for ultra-long-distance transportation.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the hot-melt strong high-performance adhesive sticker which has the characteristics of low processing temperature, adaptability to variable temperature conditions and the like, can be used for long-distance transportation, and can effectively capture harmful organisms such as mice, cockroaches and the like.
In order to achieve the technical purpose, the technical scheme of the invention is as follows:
the hot-melt strong-force high-performance adhesive sticker comprises the following components in parts by mass:
13-17 parts of EVA, 45-55 parts of polyisobutylene, 5-8 parts of butyl rubber, 0.5-2.5 parts of maleic anhydride grafted SBS, 15-25 parts of hydrogenated terpene resin and 5-10 parts of naphthenic oil.
Further, the hot-melt strong high-performance adhesive sticker comprises the following components in percentage by mass:
16 parts of EVA, 48 parts of polyisobutylene, 7 parts of butyl rubber, 1.5 parts of maleic anhydride grafted SBS, 19.5 parts of hydrogenated terpene resin and 8 parts of naphthenic oil.
The EVA comprises three types of vinyl acetate, namely one of 28wt.% (melt index of 4 g/min), 25wt.% (melt index of 19 g/min) and 40wt.% (melt index of 52 g/min), and further, in the EVA, 20-25 parts of vinyl acetate with the melt index of 4g/min, 55-65 parts of vinyl acetate with the melt index of 19g/min and 15-20 parts of vinyl acetate with the melt index of 52g/min are used. Furthermore, in the EVA, 22 parts of vinyl acetate with the melt index of 4g/min, 60 parts of vinyl acetate with the melt index of 19g/min and 18 parts of vinyl acetate with the melt index of 52g/min are used.
The polyisobutylene comprises two PIBs including a molecular weight of 1300 and a molecular weight of 2400, namely the PIB1300 and the PIB2400, wherein the polyisobutylene consists of 10-18 parts of the PIB1300 and 82-90 parts of the PIB2400, and further, the polyisobutylene consists of 14 parts of the PIB1300 and 86 parts of the PIB2400.
The butyl rubber is liquid rubber with the molecular weight of 15 w.
The preparation method of the hot-melt strong high-performance adhesive sticker comprises the steps of putting EVA and naphthenic oil into a flask, and keeping the temperature of 100 ℃ for 1h under the nitrogen atmosphere; adding butyl rubber, hydrogenated terpene resin, polyisobutylene and maleic anhydride grafted SBS after EVA is softened, blending and fusing for 4-6h at 120-130 ℃ in a homogenizer, keeping the temperature at high temperature for 1h to form a fluid state, heating to obtain high-performance adhesive sticker, spraying while hot, and cooling for transportation.
As can be seen from the above description, the present invention has the following advantages:
1. the invention solves the problems that the existing adhesive for sticking the rat and the cockroach has poor effect at low temperature, is not high temperature resistant and can not be transported far, and the low-temperature effect and the heat resistance of the strong adhesive sticker are greatly improved by blending and modifying different materials.
2. The invention takes Polyisobutylene (PIB) and butyl rubber (IIR) as main components. The butyl rubber is synthesized from isobutene and a small amount of isoprene, wherein the isobutene is low-molecular-weight isobutene, the two components form a net structure through blending, and the action mechanism of the butyl rubber is that local overstress is relieved through configuration rearrangement of unattached but mutually entangled chains. IIR has an elastic response, with uncrosslinked PIB as the viscous medium, which couples to the network through topological interactions. Since the crosslinking components turn from highly oriented to random during deformation, the PIB chains rearrange in a non-uniform manner on a sufficient length scale to relieve local overstress. This inhibits propagation of cracks, delaying macroscopic failure. The result is a stronger, stronger elastomer. At equal modulus, the blends are significantly stronger and more flexible than neat IIR networks. Therefore, the strong self-adhesive has stronger toughness and tensile strength. In addition, the polyisobutylene has good freezing resistance, can still show good adhesion force in the environment of-10 ℃, and meets the use requirement of cold regions.
3. The invention mixes ethylene-vinyl acetate copolymer (EVA)/butyl rubber (IIR) by a melting method, long-chain intermolecular winding occurs when the two substances are mixed, and the mixture is converted into a co-continuous structure from an independent dispersion structure. The EVA has a non-polar section, a polar section and a polar section, can play the role of a coupling agent, and improves the compatibility of the IIR to a polar surface or a material. In addition, the crystallization property of EVA can also enhance the mechanical property and wear resistance of the blend. Furthermore, the literature indicates for non-isothermal crystallization kinetics that the crystallization rate increases with increasing EVA content. EVA inhibits IIR molecular motion to varying degrees. The performance of the strong adhesive sticker at high temperature can be effectively improved, and the long-distance transportation capacity is greatly improved.
4. The morphology of the ethylene-vinyl acetate copolymer (EVA)/polyisobutylene blend in the invention depends on the sample heating condition, and the EVA crystal is also in a net structure formed in the PIB, so that the relaxation time of the blend tends to be average, and the viscosity of the EVA can be rapidly reduced in a heating state. The viscosity is greatly reduced (6000 +/-1000 cps) at 120-150 ℃, and the spraying production is easy.
5. The invention takes terpene resin as tackifier, has good compatibility to butyl rubber, polyisobutylene and EVA, and increases contact interface between each component. The principle of the polymer interface is mainly used as a basis, when two phases are contacted according to the basic concept of the polymer interface of the Chapter polymer interface phenomenon, molecular motion such as permeation, diffusion and the like occurs on the boundaries of the two phases due to potential energy difference of the two phases, imbalance of chemical positions, attractive force between molecules and the like, and therefore an interpenetration region is formed. The formation of this region allows sufficient intermolecular entanglement to occur, thereby improving the adhesive strength.
6. According to the invention, a small amount of maleic anhydride grafted SBS is added as a resin modifier, and anhydride groups can generate a generalized dehydration reaction with polar groups and form chemical bonds under the action of high temperature and screw shearing, so that the material has high polarity and reactivity, and thus, the chemical coupling of components such as EVA (ethylene vinyl acetate copolymer), polyisobutylene and the like is promoted, the blending degree is increased, and the processability and the impact resistance are improved.
