Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of and be difficult for that layering, brushing property are good, package stability, good toughness, good heat resistance, bonding strength height, stripping strength height, water-fast and novel glue that toxicity is little.
The present invention can be achieved through the following technical solutions:
Glue of the present invention is made up of the raw material of following parts by weight:
200~400 parts of 100~200 parts of zinc whites of 3000~6000 parts of magnesium oxide of chloroprene rubber
200~400 parts in 80~120 parts of black glue of 100~200 parts of softening oils of antiager
4000~6000 parts of 4000~6000 parts of dimethylbenzene of rubber solvent
15000~20000 parts of elastic plastics.
It is the elastomerics of being made through emulsion polymerization by the monomer chloroprene that the present invention's employing has chloroprene rubber, chloroprene rubber, is called for short CR glue.The crystallizing power of chloroprene rubber is higher than natural rubber, cis-1,4-polybutadiene rubber and isoprene-isobutylene rubber.Because mainly containing vanadium on its macromolecular chain is 1, the 4-structure as gutta-percha, is trans 1, the crystallization of 4-structure.Crystallization degree all has significant effects for the processing and the application of rubber, and general unvulcanized rubber just can produce crystallization after long-term storage, and hardness increases.Cross-linked rubber also can produce crystallization between-5~21 ℃, very fast generation crystallization below 0 ℃, and heating up can be reversibly molten brilliant.According to the purposes difference, can synthesize the rubber of different crystallizing powers by adjustment such as polymerizing conditions.
Chloroprene rubber is the stronger rubber of a kind of polarity, and the physicals of its processing performance and cross-linked rubber is subjected to Temperature Influence very big.When temperature raise, the plasticity of chloroprene rubber significantly increased, and the intensity of cross-linked rubber then significantly reduces.By the cross-linked rubber of pure glue check formulation, the tensile strength of testing under 10 ℃ of temperature must be hanged down 3.0Mpa than testing institute down at 30 ℃.
Elastic plastic has the snappiness of rubber, high strength, and high resilience, but have the feature of injection moulding processing again.And environment-protecting asepsis safety, durometer level is wide, good tint permanence is arranged, soft-touch, weathering resistance, fatigue resistance and temperature tolerance, processing characteristics is superior, need not vulcanize, can recycle and reduce cost, both can the quadric injection mould moulding, with body material coating and bondings such as PP, PE, PC, PS, ABS, strengthened the toughness of glue greatly.
Dimethylbenzene is a kind of colourless liquid, and aromatic odour is arranged, and is volatile, is insoluble in water, littler than water-mass density, can dissolve multiple organism, is the solvent of using always.It is by the strippings of fractionating coal tar or catalytic reforming light oil through fractionation, or form through disproportionation by toluene.
Described rubber solvent is the neoprene toluene solvant, and it can be fit to the solvent for chloroprene rubber, paracril isopolarity rubber.
Adopt the styrenated phenol antiager, promptly be called for short SP, it is the anti-aging agent of a kind of uncontamination nondiscoloration, good dispersion property, can make the stablizer of synthetic rubber such as butylbenzene, neoprene, Ding Qing and natural rubber, good anti-aging effect is all arranged in rubber and latex product, can improve goods heatproof oxidation performance energy.
The present invention can be with product application bonding between each field product, for example with this product application in this bonding of submarine armor class, can be applied to this product between the fare or be coated in the bonding centre that does not have fare, make that product is firm, smooth, Li Shui, flexible, avoid fare to be rubbed, the people is reduced friction at the volley, skin and product are all play to the effect of reducing wear.
The present invention compared with prior art has following advantage:
The present invention adopts chloroprene rubber, magnesium oxide, zinc white, antiager, softening oil, black glue, rubber solvent, dimethylbenzene and elastic plastic through the reasonably combined glue of making, have behind the glue of making that the layering of being difficult for, brushing property are good, characteristics such as package stability, good toughness, good heat resistance, bonding strength height, stripping strength height, water-fast and toxicity are little, low cost of manufacture, convenient and practical.
