Abstract
The invention relates to a formula of a permanent deformation prevention type buffer block. The formula comprises the following components in percentage by mass: 68%-82% of vinyl silicone rubber, 3%-8% of di-tert-butyl peroxide, 4%-10% of silicon dioxide, 3%-6% of zinc oxide and 6%-14% of tetramethyl ethylidene dimethyldialkoxysilane. The formula has the advantages of reasonable matching, low cost, stable performance, good forming quality and the like. When the compression ratio of the permanent deformation prevention type buffer block is 30%, after the permanent deformation prevention type buffer block is compressed for 24-72 hours at the temperature of 150 DEG C, the rate of the permanent deformation of the buffer block is 12%-16% (the common silicon rubber is 20%-30%).
Description
Technical field
The present invention relates to the elastomeric material technical field, is a kind of formula of resistance to permanent deformation type buffer block specifically.
Background technology
Buffer block mainly plays and reduces instant impact, protection is used object, reduced the effects such as noise, the vibrations of reduction equipment.Therefore, buffer block has a wide range of applications at aspects such as industry, life, vehicle, mechanical means.The materials of buffer block generally are divided into polystyrene foamed plastics, polyethylene foams, urethane foam, polyvinyl chloride foam and polypropylene foam etc.But viscous deformation, after long-term pressurized, very easily occurs in general buffer block, affects the functional quality of buffer block.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of reasonable ratio, with low cost, stable performance, buffer block formula that Forming Quality is good, i.e. a kind of formula of resistance to permanent deformation type buffer block.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of formula of resistance to permanent deformation type buffer block, this formula comprises vinylsiloxane rubber, di-t-butyl peroxide, silicon-dioxide, zinc oxide, tetramethyl-ethylidene dioxy dimethylsilane, the shared mass percent of described each component is as follows:
The shared best in quality per-cent of described each component is as follows:
The performance of described each component and effect are as follows:
Vinylsiloxane rubber: the rubber as silica gel product is used, and anti-deformation nature is good.
Di-t-butyl peroxide: the agent of vinylsiloxane rubber dedicated vulcanization, can decompose rapidly the generation free radical under higher curing temperature, thereby it is crosslinked that ethylene rubber is produced.
Silicon-dioxide: the main raw of the reinforcing filler of silicon rubber claims again white carbon black.Silicon-dioxide can be divided into thermal silica and precipitated silica.Fumed silica is one of the most frequently used strengthening agent of silicon rubber,, good electrical property high by the physical strength of its cross-linked rubber of sizing material of its reinforcement, and can with other strengthening agent or weak strengthening agent use, prepare the sizing material of different service requirementss.
Zinc oxide: weak reinforcing filler, they generally do not use separately in rubber, but with silicon-dioxide use, to regulate the hardness of rubber, improve the processing performance of sizing material and oil resistance and the solvent resistance of cross-linked rubber, reduce the cost of sizing material.
Tetramethyl-ethylidene dioxy dimethylsilane: constitution controller, meeting hardening in the silicone rubber compounds storage process of employing fumed silica reinforcement, plasticity value descends, and loses gradually process industrial art performance, and this phenomenon is called " structurizing " effect.For preventing and weaken that the Synergist S-421 95 that this " structurizing " tendency adds is called " constitution controller ".
The invention has the beneficial effects as follows: the present invention has the advantages such as reasonable ratio, with low cost, stable performance, Forming Quality be good, when rate of compression is 30%, after 150 ℃ of lower compression 24～72h, be permanently deformed to 12%～16% (ordinary silicon rubber is 20%～30%).
