Abstract
The present invention provides an adhesive for modified polystyrene table tennis balls and belongs to the technical field of table tennis ball manufacturing. The adhesive provided by the present invention is composed of the following components in parts by weight: 20-40 parts styrene, 15-20 parts of methyl acrylate, 5-10 parts of a photoinitiator, 5-8 parts of modified nano-inorganic filler, 0.2-0.5 part of p-tert-butylcatechol, 1-4 parts of dibutyl phthalate and 30-50 parts of a diluent. Under the action of UV-light, a radical polymerization reaction is initiated on the adhesive to produce a polystyrene and polymethyl acrylate copolymer which has relatively good compatibility and cohensiveness with the modified polystyrene table tennis ball bodies, and the mechanical strength of the adhesive is enhanced by adding the inorganic filler and various additives, so that the storage stability and weather resistance are improved. The adhesive has the advantages of aging resistance and non-curing at room temperature, and meanwhile, the elastic force and the mechanical strength of table tennis balls are not affected.
Description
Technical field
The invention belongs to table tennis manufacturing technology field, be specifically related to a kind of modified polystyrene table tennis ball and stick with glue agent.
Background technology
Started from 1891, zylonite is exactly the material manufacturing table tennis.Zylonite is processed into by the nitrocotton, softening agent, lubricant, dyestuff etc. of low nitrogen content.Zylonite has higher consistency and elasticity modulus, obtained table tennis has water-fast, oil resistant, acidproof, the uniform advantage of long service life, thickness, but its easy firing, and discharge a large amount of pungency toxic gas during burning, in production and transport, have very big potential safety hazard, the table tennis production material therefore seeking a kind of alternative zylonite becomes problem demanding prompt solution.
In order to solve the deficiency of existing zylonite table tennis, applicant develops a kind of novel modified polystyrene table tennis ball, there is the advantages such as good springiness, shock resistance is strong, potential safety hazard is few, and it is easy to process, substantially reduce the production cycle of table tennis, improve production efficiency, reduce production cost.Modified polystyrene table tennis ball is raw material with modified polystyrene, is injection molded into two hemisphere, then by tackiness agent, two hemisphere bondings is obtained finished ball.Tackiness agent used need have the feature boning instantaneously, do not solidify under good, ageing-resistant, the room temperature of physical strength.
Summary of the invention
The invention provides a kind of modified polystyrene table tennis ball special-purpose adhesive, can bond instantaneously, there is the advantage that ageing-resistant, room temperature is not solidified, do not affect elastic force and the physical strength of table tennis simultaneously.
The technical scheme of technical solution problem provided by the present invention is:
A kind of modified polystyrene table tennis ball sticks with glue agent, and described tackiness agent is made up of following parts by weight component: 20-40 part vinylbenzene, 15-20 part methyl acrylate, 5-10 part light trigger, the mineral filler of 5-8 part modified Nano, 0.2-0.5 part p-ten.-butylcatechol, 1-4 part dibutyl phthalate (DBP) and 30-50 part thinner.
Under the effect of photocatalyst and UV-light, there is radical polymerization fast, generate the multipolymer of polystyrene and polymethyl acrylate, thus cohesive action is risen to table tennis hemisphere in vinylbenzene and methyl acrylate.Gained multipolymer and modified polystyrene table tennis ball have excellent consistency and cohesiveness.Modified Nano mineral filler can increase the physical strength of tackiness agent, avoids table tennis to cause breaking because seam crossing intensity is too low.P-ten.-butylcatechol is a kind of conventional thermosensitive type stopper, plays inhibition during normal temperature storage, and when adopting uv-light polymerization, system temperature raises, and now p-ten.-butylcatechol decomposition failure, makes polyreaction normally carry out.Dibutyl phthalate (DBP), as softening agent, can improve ageing resistance and the toughness of tackiness agent, can make up the defect that Adhensive performance based on polystyrene is more crisp.The plasticity of system can be promoted simultaneously, improve elasticity and improve winter hardiness, and increasing the mobility of system, be conducive to moistening, diffusion and absorption, thus improve use properties and the bond strength of tackiness agent.
As preferably, described light trigger is selected from the one in 1-hydroxycyclohexylphenylketone, dicumyl peroxide, dibenzoyl peroxide, benzophenone.
As preferably, described thinner is selected from the one in toluene, chloroform and ethyl acetate.The effect of thinner is dissolve polymer monomer, initiator and other auxiliary agents, increases the mobility of binding agent.
As preferably, described modified Nano mineral filler is the one in modified manometer silicon dioxide, modified nano-titanium dioxide or modified Nano glass microballon.
As preferably, the preparation method of described modified Nano mineral filler is: nanometer inorganic filler joins in aqueous ethanolic solution by (1), and makes it fully disperse under strong stirring; (2) step (1) gained mixed solution is heated to 65-75 DEG C, adds silane coupling agent, and adopt oxalic acid regulation system PH to 3-4, after insulation reaction 1-3 hour, be cooled to normal temperature and suction filtration; (3) get step (2) gained filter cake washing 2-3 time after, drying, grinding, mistake 100 mesh sieves namely obtain modified Nano mineral filler.Because surface of inorganic particles generally has wetting ability, with hydrophobic polymkeric substance, poor compatibility between the polymeric matrix of particularly nonpolar or low-pole, therefore the interface adhesiveness of polymer/inorganic particle matrix material is weak, directly causes the mechanical property of matrix material undesirable.For preparing high performance polymer/inorganic particle composite material, modification must be carried out to surface of inorganic particles, realizing the bonds well of particle surface and polymeric matrix, thus obtaining the matrix material of excellent property.
More preferably, the massfraction of described aqueous ethanolic solution is 30-40%, and the quality of described aqueous ethanolic solution is 2-4 times of mineral filler quality.
More preferably, described silane coupling agent is selected from the one in KH550, KH560 and KH570.
More preferably, the quality that feeds intake of described silane coupling agent is 0.2-0.4 times of nanometer inorganic filler quality.
As preferably, described tackiness agent is made up of following parts by weight component: 25 parts of vinylbenzene, 20 parts of methyl acrylates, 10 parts of light triggers, 6 parts of modified Nano mineral fillers, 0.5 part of stablizer, 4 parts of dibutyl phthalate (DBP)s and 35 parts of thinners.
Beneficial effect of the present invention is:
Modified polystyrene table tennis ball special-purpose adhesive provided by the present invention, can bond instantaneously, has the advantage that ageing-resistant, room temperature is not solidified, and does not affect elastic force and the physical strength of table tennis simultaneously.
