For these problems, people begin with biological pesticide or physical measure to prevent and treat agriculture and forestry injurious insect, and this is also the important means reducing pollution by pesticides, producing green agriculture and forestry product, pest control.
Recent years, insect sticker has begun to be applied in Pest control as a kind of physical pest killing technology. Utilize the part insect that forest, fruit tree or vegetable etc. occur to survive the winter on ground, then then through the life habit of trunk context tree procreation harm, use insect sticker to cling the insect that climbs the tree, thus it is not compromised to reach forest reserve fruit. But, adopting more mythimna separata agent at present is that raw material that is solvent type or that select is relatively big to people's zest, and environment can be worked the mischief. On the other hand, insect sticker ubiquity holds viscosity and the poor shortcoming of weatherability, have impact on the effect of practical application.
Chinese invention patent CN102618190A discloses efficient insect sticker in a kind of pollution-free vegetable orchard and preparation method thereof, have employed paraffin, polyisobutylene, naphthenic oil, white oil, atactic polyolefin, SIS, Colophonium pentaerythritol resin, C5 hydrogenated petroleum resin, antioxidant and ultraviolet (UV) resistant agent in the method. This insect sticker stable performance, good weatherability, anti-hang down fluidity can good, tack retention hour is long, can use up to 20 days.
But insect sticker is after clinging insecticide, insecticide can struggle with strength, and the insecticide strength that some individuals is bigger is relatively big, requires very high to the cohesiveness of insect sticker, and the cohesiveness of this insect sticker still has much room for improvement.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of butyl rubber hot melt adhesive and preparation method thereof.

POE(polyolefin elastomer) it is that DOW chemical company of the U.S. has narrow molecular weight distribution and the thermoplastic elastomer (TPE) of uniform short-chain branch distribution with what metallocene was catalyst. The main performance of this elastomer is very prominent, has exceeded conventional elastomers in very many-sided performance indications.
POE molecular structure is similar to ethylene propylene diene rubber (EPDM), therefore POE also can have the excellent properties such as ozone ageing-resistant, resistance to, resistant to chemical media, by POE is cross-linked, the heat resisting temperature of material is enhanced, permanent deformation reduces, and the Main Mechanical such as hot strength, tearing strength all has significant improvement.
APAO(amorphous state alpha olefin copolymer, Amorphouspolyalphaolefin) it is a kind of low-molecular-weight amorphous state plastic body material, generated by the aggregated reaction of a-alkene, it microstructure is a kind of ordered state amorphous, random, therefore this material has the characteristic not available for many crystalline polymers, therefore in its application, also there is particularity. It mainly as binding agent, strengthens the adhesive force with ground and cohesive force in PUR.
Styrene ethylene-propylene-styrene type block copolymer (SEPS) has shorter methyl group unit series, thus without crystallization. Not having crystallization in EP rubber segments, so SEPS is more soft than the SEBS of partially crystallizable, the elastic and delayed behavior of SEPS is all better than corresponding SEBS; When with oil as the plasticizer of rubber segments, based on SEPS, the pliability of the thermoplastic elastomer (TPE) of glue is further strengthened. The intrinsic characteristic of hydrogenated polyisoprene polymer should be able to make the styrenic thermoplastic elastomer based on SEPS have this superpower pliability and high resiliency.
Molybdenum bisuphide is important kollag, is particularly well-suited under High Temperature High Pressure. It is described as " senior solid oil king ".
