Abstract
The invention relates to high-resilience molded plastic and a preparation method thereof. The high-resilience molded plastic is prepared from a component A and a component B, wherein the component A includes the following materials (in parts by weight): 60-80 parts of polyether polyol DEP (Diethyl Phthalate)-330N, 20-40 parts of polymer polyol POP(Polyolefin Plastomer) -9328, 2.8-4 parts of water, 0.55-0.8 part of foam stabilizer AK7731, 0-0.06 part of amine catalyst A1, 0.45-0.55 part of amine catalyst A33 and 2.0-3.0 parts of cross-linking agent MN550E; and the component B includes 43-55 parts of black materials TM. The preparation method of the high-resilience molded plastic comprises the following steps of: adding the materials of the component A to a stirrer for uniformly mixing; adjusting the constant material temperature to 23 DEG C-27 DEG C; adjusting the rotation speed of the stirrer to 5000r/min; pouring the component B which is pre-heated to 23 DEG C-27 DEG C to the component A for stirring for 5 seconds; pouring the mixed materials to a mould which is pre-heated to 35 DEG C-45 DEG C; de-molding after 5 minutes-10 minutes; and testing the performances after 24 hours. The high-resilience molded plastic disclosed by the invention has long initiating and gas discharging time, no flatulence and good performances on hardness, strength and tensile strength.
Description
Technical field
The present invention relates to a kind of high resilience molding and preparation method thereof, belong to chemical field.
Background technology
Polyurethane foam now has been applied to all trades and professions as a kind of good synthetic plastics.Moulded parts is used to industries such as automobile, top-grade furniture more with comfortable performance.
The high resilience goods of present molding are many in making processes to be linking agent with the diethanolamine, diethanolamine in use, add-on can cause that too much the foam closed pore can cause that also hardness is soft partially, the linking agent that the present invention adopts can effectively improve this phenomenon.
Summary of the invention
Technical problem to be solved by this invention provides a kind of with deflation time length, no flatulence and the high resilience molding of superperformance is being arranged aspect hardness, intensity and the tensile strength.
A kind of high resilience molding of the present invention, formulated according to following ratio of weight and number by A and two kinds of components of B:
The A component:
The B component:
43～55 parts of black material TM
Described linking agent MN550E believes the polyether glycol that federal chemical Industrial Co., Ltd produces for Zibo moral, public offering, and this product is 2～5 functionality, polyoxyethylene segment 50～95%, molecular weight are 500～1000 superpolymer.
The preparation method of described high resilience molding is as follows:
Each raw material of A component is added agitator to mix, adjust 23-27 ℃ of constant material temperature, regulate agitator speed to 5000r/min, the B component that is preheated to 23-27 ℃ poured in the A component stir 5s, mixture is poured in the mould that is preheated to 35-45 ℃, the demoulding behind the 5-10min, test performance behind the 24h.
The invention has the beneficial effects as follows:
(1) linking agent of Cai Yonging has certain perforate effect, and is slower to the catalysis of induction system, and flow effect is preferably arranged when the product molding of complexity.
(2) the high resilience molding that utilizes linking agent of the present invention to make has longer time and the deflation time of rising, and does not have flatulence, is improved largely in hardness, resilience and tensile strength, presses the degree that falls into littler.
