Abstract
The invention relates a high-damp structure composition and a processing method thereof as well as a shock-insulating rubber support comprising the structure. The structure has light weight, high strength and ageing resistance and is easy to process while high damp is ensured. The structure composition comprises the following components in parts by weight: 100 parts of thermoplastic polyurethane, 20-50 parts of glass fiber, 30-100 parts of damping agents and 1-2 parts of stearic acid. The processing method comprises: 1) activation; 2) plastication; 3) feeding; and 4) formation. According to the invention, thermoplastic polyurethane is used as a main body, the glass fiber is used as a reinforcing agent, and flaky mica powder, graphite powder and silica powder are used as the damping agents. After an inorganic high-damp filling material is added, a rigid space structure is formed in the material so that the elasticity of a prepared product is further reduced, and simultaneously, the prepared product has better high damp property and easily-processing property. The high-damp structure composition provided by the invention can substitute for the lead core of the traditional lead core shock-insulating rubber support.
Description
Technical field
The shock insulation rubber bearing that the present invention relates to a kind of novel high damping structural part material, working method and include this structural part.
Background technology
In order shock insulation rubber bearing to be had meet the horizontal characteristic of shockproof requirements, Japan proposed a kind of design concept of lead core rubber support previously, and corresponding product is provided.After it is pressed into lead for retractable pencil, combines together with rubber support and to follow transverse shear deformation, this kind bearing is by stabile restoring means of rubber support and the plumbous one-piece type earthquake isolating equipment of the damping mechanism that energy absorbing device constituted." isolation structure design " (Architectural Institute of Japan's work, Earthquake Press) carried out more detailed explanation to this product.Lead is a kind of soft heavy metal, is a kind of malleable weak metal, has damping capacity preferably, but plumbous weight is big, price is high, toxic, pollution is arranged, do not meet the growth requirement of society.
Summary of the invention
The present invention is directed to above problem, provide a kind of when guaranteeing high damping, in light weight, intensity is high, ageing-resistant, be prone to high damping structural part compsn, the working method of processing and comprise the shock insulation rubber bearing of this structural part.
High damping structural part compsn of the present invention comprises following component (weight part): 30 ~ 100 parts of 100 parts of thermoplastic polyurethanes, 20 ~ 50 parts in spun glass, damping agent and 1 ~ 2 part of Triple Pressed Stearic Acid.
Said damping agent comprises in flaky mica powder, Graphite Powder 99, the silicon dioxide powder one or more compound.
The working method of high damping structural part compsn of the present invention, processing according to the following steps:
1), activation treatment; Adopt silane coupling agent that spun glass is carried out surface activation process, get the activation spun glass, for use;
2), refining is moulded; Plasticated 4 ~ 5 minutes in the plasticating equipment with 175 ~ 185 ℃ of thermoplastic polyurethane inputs;
3), feed intake; Aforementioned activation spun glass and Triple Pressed Stearic Acid are dropped in the thermoplastic polyurethane of preceding step mixing 5 ~ 7 minutes; Added said damping agent then mixing again 8 ~ 10 minutes;
4), moulding; To go up the step material and be machined as section bar through extrusion moulding; After the cooling, cut and make structural part.
The shock insulation rubber bearing that comprises high damping structural part compsn of the present invention; Said shock insulation rubber bearing has centre hole; Said high damping structural part cut become with the adaptive shape of said centre hole after, the high damping structural part after said the cutting is embedded in the said centre hole.
It is main body that the present invention adopts thermoplastic polyurethane; With the spun glass is strengthening agent; With flaky mica powder, Graphite Powder 99, silicon dioxide powder is damping agent; And to be aided with Triple Pressed Stearic Acid be processing aid, forms through special processing and fabricating.Thermoplastic polyurethane is made up of soft section of flexibility and the hard section of rigidity; Contain a large amount of hydrogen bonds; Because the incompatible microphase-separated that caused of thermodynamics of hard section and soft section; This constructional feature of urethane has been given its excellent performance, therefore has higher damping loss factor, is a kind of reasonable damping material.After adding the spun glass of activated processing; Spun glass combines more firmly with main body; And then can the elasticity of thermoplastic polyurethane and the high rigidity of spun glass organically be combined, significantly improve rigidity modulus, and then make finished product have characteristics such as HS, easy processing.Add flaky mica powder, behind the inorganic high damping fillers such as Graphite Powder 99, silicon dioxide powder, in material, constitute the inflexible space structure, the elasticity of the article of making is further reduced, have better high damping properties and workability ability simultaneously.Lead for retractable pencil in the alternative traditional lead for retractable pencil shock insulation rubber bearing of the present invention.
