Abstract
A preparation method of liquid plastic comprises the following steps of: evenly mixing the formula of the liquid plastic according to a certain proportion and then hermetically storing for 2-3 days; evenly stirring precipitates before heating and then putting the mixture into a far infrared oven at a temperature of 100 DEG C; stirring the mixture and taking the mixture out every once in a while; stirring the mixture for multiple times to form a pasty material; then adjusting the temperature in the far infrared oven to 140-150 DEG C till the state of the mixture changes from pasty to light brown liquid; and keeping the temperature for 10-20 minutes to obtain the liquid plastic for casting clamps. The invention has the advantages of simple method, low working intensity and even temperature rise and capability of shortening preparation time. Plastics prepared through the method have good quality and produce a few bubbles.
Description
Technical field
The present invention relates to a kind of preparation method of liquid plastics, be mainly used in the precision optical machinery manufacturing.
Background technology
Liquid plastics is a kind of similar gels shape ground plastics, because it has certain fluidity, under certain pressure, can pressure evenly be transmitted everywhere as liquid, and it does not under high pressure decompose, non-leakage, corroding metal not, so generally be used for the filler of machine industry as high-accuracy clamp, the preparation method who adopts has two kinds at present, a kind of method is to put into the glycerine pot that fills with mineral oil after prescription is mixed by a certain percentage to heat, another kind method is that mixture is put into beaker, beaker is imbedded in the pot that fills with yellow sand again, heats with electric furnace.Adopt that a kind of method all to have some shortcomings,, temperature bad control (140-150 ℃) long as heat time heating time, do not stop to stir, easily roasting bad, can produce a large amount of bubbles etc.Have a strong impact on the anchor clamps quality and the popularization of liquid plastics.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide that a kind of method is simple, working strength is low, temperature rise is even, and can shorten the preparation method of preparation time liquid plastics, the plastic quality of this method preparation is good, and it is few to produce bubble.
The technical scheme that realizes above-mentioned purpose is: a kind of preparation method of liquid plastics, and the step of this method is as follows:
The prescription of liquid plastics is evenly mixed the back sealing by a certain percentage to be deposited 2 ~ 3 days, before heating, earlier sediment is stirred, put into the far infrared baking oven baking that is set in 100 ℃ then, whenever stir after a while and take out once, stir and repeatedly it is stirred into pasty state, then the temperature in the far infrared baking oven is transferred to 140 ~ 150 ℃,, be incubated the liquid plastics that promptly obtained pouring into a mould usefulness in 10-20 minute as anchor clamps up to become light brown liquid state by pasty state.
The present invention adopts Far-infrared Heating, and Far-infrared Heating is a radiation heating, compares with traditional heating means such as steam, hot blast and resistance, has that energy-conservation, heat temperature raising is fast, a homogeneous heating, characteristics such as pollution-free.By adopting Far-infrared Heating to make the present invention have following advantage:
(1) preparation method is simple.
(2) Zhi Bei plastic quality is good, and it is few to produce bubbles volume.
(3) working strength is low, need not stop in preparation process to stir, as long as stir 3 times always.(4) temperature rise is even, but the control of temperature temperature can not baked bad plastics.
(5) preparation time is short, has only 1/8 of traditional time ~/10.
The specific embodiment
The present invention is further detailed explanation below in conjunction with embodiment.
Embodiment one
Polyvinyl chloride resin powder, vacuum oil, dibutyl phthalate, calcium stearate are evenly mixed 300g by a certain percentage, sealing room temperature fermentation 3 days, put into the far infrared baking oven, be preheating to 100 ℃, stir about 5 minutes once, can stir into pasty state, then the temperature in the far infrared baking oven is arranged on 148 ℃ for 3 times, up to become light brown liquid state by pasty state, be incubated the liquid plastics that promptly obtained pouring into a mould usefulness in 20 minutes then as anchor clamps.During insulation, anchor clamps are put into the far infrared baking oven together be incubated, can pour into a mould after 20 minutes.
The actual proof of using is used these anchor clamps the housing two ends endoporus axiality of high-speed electric main shaft can be stablized and is controlled in the 0.002mm.
Embodiment two
Polyvinyl chloride resin powder, vacuum oil, dibutyl phthalate, calcium stearate are evenly mixed 300g by a certain percentage, sealing room temperature fermentation 2 days, put into the far infrared baking oven, be preheating to 100 ℃, stir about 5 minutes once, can stir into pasty state, then the temperature in the far infrared baking oven is arranged on 148 ℃ for 3 times, up to become light brown liquid state by pasty state, be incubated the liquid plastics that promptly obtained pouring into a mould usefulness in 15 minutes then as anchor clamps.During insulation, anchor clamps are put into the far infrared baking oven together be incubated, can pour into a mould after 15 minutes.
Embodiment three
Polyvinyl chloride resin powder, vacuum oil, dibutyl phthalate, calcium stearate are evenly mixed 300g by a certain percentage, sealing room temperature fermentation 3 days, put into the far infrared baking oven, be preheating to 100 ℃, stir about 5 minutes once, can stir into pasty state, then the temperature in the far infrared baking oven is arranged on 148 ℃ for 3 times, up to become light brown liquid state by pasty state, be incubated the liquid plastics that promptly obtained pouring into a mould usefulness in 10 minutes then as anchor clamps.During insulation, anchor clamps are put into the far infrared baking oven together be incubated, can pour into a mould after 10 minutes.
