Abstract
Disclosed is a high elasticity sponge which comprises the components (by weight portion) of natural gum 20-35, synthesized rubber 20-35, resin 30-60, metallic oxide 2-10, aliphatic acid 2-6, cross linking agent 3-5, accelerating agent 2-6, blowing agent 10-16, urea derivative 15-20, anti-aging agent 2-4.
Description
Technical field
The invention belongs to polymeric material field; The material that uses as electronic glass industry grinding and polishing consumptive material particularly.
Background technology
Electronic glass industry glass deep processing technology has been determined the harshness to the grinding and polishing material requirements, its requirement does not absorb water, under the effect of dynamic flexing pressure, still keep good imitative type effect and damping performance, therefore the following physical performance index of grinding and polishing material: it is particularly important to pull apart brute force, elongation, hardness, tension set, and original sponge of using all is serve as main investigation parameter with its hardness, so original sponge product can not satisfy the processing requirement of electronic glass industry.
Most of rubber can both be made common sponge, therefore select which kind of rubber for use, whether need two or more polymkeric substance and usefulness, are the concrete working conditionss according to sponge product, decide as working order, medium, ambient moisture.Following four kinds of prescription A, the natural rubbers (or natural rubber+synthetic rubber) of adopting of sea main body originally more; B, synthetic rubber (or synthetic rubber+natural rubber); C, natural rubber+EVA+ polyethylene (natural rubber+resin) are annotated: based on resin; D, synthetic rubber+polyethylene (synthetic rubber+resin) are annotated: based on resin.The sponge of these prescriptions all do not have as the grinding and polishing material should possess do not absorb water high-tenacity, high elongation rate and lower tension set performance.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, a kind of high elasticity sponge of processing requirement of suitable electronic glass industry is provided.
The object of the present invention is achieved like this: high elasticity sponge comprises following component and weight ratio: natural gum 20-35, synthetical glue 20-35, resin 30-60, metal oxide 2-10, lipid acid 2-6, linking agent 3-5, promotor 2-6, gas generation agent 10-16, urea derivative 15-20, anti-aging agent 2-4.
Prescription of the present invention compared with prior art has the following advantages: high elasticity sponge does not absorb water, brute force is high, elongation is high, has satisfied the service requirements of electronic glass industry rubbing down equipment fully, and performance is excellent, effective.
Recently proportioning is best with following weight: natural gum 30, synthetical glue 30, resin 40 for three kinds of main components in the above-mentioned prescription.That is: natural gum: synthetical glue: resin=3: 3: 4.
Embodiment
Example 1: seek best glue kind ratio:
| Component | 1 | 2 | 3 |
| Natural gum | 20 | 30 | 35 |
| Synthetical glue | 20 | 30 | 35 |
| Resin | 60 | 40 | 30 |
| Metal oxide | 2-10 | 2-10 | 2-10 |
| Lipid acid | 2-6 | 2-6 | 2-6 |
| Linking agent | 3-5 | 3-5 | 3-5 |
| Promotor | 2-6 | 2-6 | 2-6 |
| Gas generation agent | 10-16 | 10-16 | 10-16 |
| Urea derivative | 15-20 | 15-20 | 15-20 |
| Anti-aging agent | 2-4 | 2-4 | 2-4 |
Above-mentioned three groups of experimental formulas are measured through powerful experimental machine, natural rubber and elastomeric proportioning the best of prescription 2.
Example 2: the glue kind of seeking best synthetical glue
Drawing elastomeric best glue kind by above-mentioned experiment is styrene-butadiene rubber(SBR).
Example 3: find out gas generation agent and the best proportioning of sending out the hole auxiliary agent
Drawing gas generation agent by above-mentioned experiment is 1: 1.3 ~ 1.6 with the best proportioning of sending out the hole auxiliary agent.
Example 4: actual production prescription
The high elasticity sponge durometer level that the present invention produces is wide, and outward appearance is well-pressed, the aperture uniformity; Physicals detects its product brute force: 5-8MPa, elongation more than 300% through quality examination center, Tianjin, and tension set is less than 10%, hardness 10-60 degree.Best results in national electronic glass industry glass deep processing is used, share of market first.Satisfied the service requirements of electronic glass industry production.
Our company's name of product is that bubble is continuous, since not easy-to-understand, so change sponge into.
