Detailed Description
The invention provides a silica gel cup and a preparation method thereof, and in order to make the purpose, technical scheme and effect of the invention clearer and clearer, the invention is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Referring to fig. 1, the invention provides a preparation method of a silica gel cup, wherein the silica gel cup comprises a cup body 1, a cup cover 2 and a straw fixing seat 4, and the preparation method comprises the steps of respectively preparing the cup body, the cup cover, the straw fixing seat and assembling and forming; the preparation of the cup body, the cup cover and the straw fixing seat comprises the following steps:
adding the organic raw silica gel, a vulcanizing agent and color master batch into a rubber mixing machine for repeated refining to prepare silica gel; the strong mechanical shearing action of the rubber mixing machine is utilized to simultaneously play a physical and chemical role between the raw materials, and the rubber mixing machine has proper fluidity, fineness and uniformity and meets the requirements of product molding and use. Specifically, if a colorless product is prepared, color master batch can be not added. Here the thickness of the silica gel was controlled by controlling the gap between the rollers of the rubber mixing mill.
Cutting silica gel into certain specifications, respectively putting the cut silica gel into a mold matched with the cup body, the cup cover or the fixed seat in shape, and performing compression molding by closing an upper mold and a lower mold; the silica gel is cut into certain specifications, so that the silica gel is conveniently placed in a mold, waste is reduced, and the difficulty of subsequent treatment of the edge part is reduced. Specifically, the molds (upper mold and lower mold) are high temperature molds, and the organic raw silica gel is melted at high temperature and cured (hardened) at high temperature under the action of a vulcanizing agent and the pressure of a machine table.
And taking out the semi-finished product in the die for secondary baking. The compression molding is equivalent to primary baking, and secondary baking is favorable for volatilization of organic volatile matters and further molding of the organic crude silica gel.
It should be noted here that the cup body, the cup cover and the straw fixing seat are all prepared in independent preparation processes, and there is no sequence.
The preparation method is simple, and the cup body, the cup cover and the straw fixing seat are prepared by the same preparation method, so that the quality of the silica gel cup can be better controlled; the compression molding has the characteristics of high production efficiency, high product size precision, smooth and clean preparation surface and the like, and is beneficial to the batch production of the cup body, the cup cover and the straw fixing seat; and after the production is finished, assembling to obtain the silica gel cup.
Further, the cup body, the cup cover and the straw fixing seat all comprise 94-98% of organic crude silica gel, 1-3% of vulcanizing agent and 1-3% of color master by mass percentage. Specifically, the organic raw silica gel is methyl vinyl dimethyl (siloxane and polysiloxane), and the vulcanizing agent enables the organic raw silica gel to be subjected to polycondensation reaction rapidly under a high-temperature and high-pressure environment, so that the organic raw silica gel is crosslinked and cured to a certain degree and achieves certain physical and mechanical properties. The silica gel cup prepared from the components reaches the food grade, does not contain harmful substances such as BPA (bisphenol A), phthalate, polyvinyl chloride and the like, and can be cleaned by a dish-washing machine.
Further, when the cup body is formed by pressing, the mould pressing temperature is 150-2. The temperature and the pressure in the range are favorable for accelerating the polycondensation reaction, the molding temperature is too high, the organic raw silica gel is decomposed, the curing speed is too high, the outer layer is cured firstly and does not flow any more, volatile gas is difficult to discharge, and the internal stress is increased; the molding temperature is too low, the curing is incomplete, and the curing time is prolonged; the flow of the materials is accelerated by applying pressure; the material is compacted, so that the compactness is improved; the pressure generated by volatilization of low molecular substances is overcome, and bubbles, swelling or delamination of the product is avoided; the size and shape of the product are maintained, and the product is prevented from cooling and deforming. Within the range of the molding time to achieve a certain degree of crosslinkingThe degree is that the reaction time is prevented from being too short, so that the solidification is not complete; the curing time is too long, and the pressure in the product is large. In the compression molding process, the organic raw silica gel is plasticized at high temperature and high pressure and has certain fluidity, the organic raw silica gel gradually reacts under the action of a vulcanizing agent to generate crosslinking, and the organic raw silica gel loses the fluidity after the crosslinking is carried out to a certain degree and is solidified into a shape with certain mechanical strength.
Further, when the cup body is baked for the second time, the baking temperature is 200 ℃, and the baking time is 4 hours. The temperature in the secondary baking is higher than the mould pressing temperature of the mould pressing forming, so that the curing forming of the product is further ensured, and the post-curing is more thorough; moreover, this baking process can guarantee that volatile substances fully volatilize, avoids the outside or the inside of goods to produce a large amount of gas pockets, reduces the shrinkage factor of cup body moreover, prevents simultaneously that the consumer from having volatile substances to produce the use impression that influences the silica gel cup when using.
Further, when the cup cover is pressed and formed, the mould pressing temperature is 150-2。
Further, when the cup cover is baked for the second time, the baking temperature is 200 ℃, and the baking time is 4 hours.
Further, when the straw fixing seat is pressed and formed, the mould pressing temperature is 150-2。
Further, when the straw fixing seat is baked for the second time, the baking temperature is 200 ℃, and the baking time is 4 hours.
Referring to fig. 2-3, the invention also provides a silica gel cup, which is manufactured by the preparation method of the silica gel cup, and the silica gel cup comprises a cup body 1, a cup cover 2, a suction pipe 3 and a suction pipe fixing seat 4; the cup cover 2 is arranged on the upper portion of the cup body 1 in a covering mode, a first through hole 5 is formed in the middle of the cup cover 2, the straw 3 is arranged in the first through hole 5, a second through hole 6 penetrating through the straw fixing seat 4 is formed in the middle of the straw fixing seat 4, and the straw 3 is arranged in the second through hole 6. When the equipment, with bowl cover 2 lid on the upper portion of cup body 1, shelter from the rim of a cup of cup body 1, insert straw 3 in first through-hole 5, insert straw 3 with second through-hole 6 again, make the lower surface of straw fixing base 4 and the upper surface of bowl cover 2 contact. When the cup is used, the beverage in the cup body 1 can be sucked through the suction pipe 3, or the beverage can be directly sucked from the cup opening of the cup body 1 by opening the cup cover 2, so that the cup is multifunctional and has strong interestingness.
Specifically, the aperture of the first through hole 5 is matched with the aperture of the suction pipe 3, so that the sealing effect is improved, and the suction pipe 3 also plays a role in air dissipation; the aperture of the second through hole 6 is matched with the aperture of the suction pipe 3, so that the positioning effect of the suction pipe 3 is improved, and the suction pipe 3 is prevented from shaking.
Furthermore, the shore hardness of the cup body 1 is 70HD, the shore hardness of the cup cover 2 is 70HD, and the shore hardness of the straw fixing seat 4 is 50 HD. The 70HD is medium-hard plastic, so that the cup body 1 and the cup cover 2 have certain hardness, the cup body 1 or the cup cover 2 cannot be deformed by hands due to soft texture, the beverage of the cup body 1 is leaked, or the sealing degree of the cup body 1 by the cup cover 2 is reduced. 50HD is soft plastic, is convenient for insert in straw 3 with straw fixing base 4.
