Description

One kind is high performance to exempt from inflatable bicycle PU tire production foaming agents
Technical field
Used the present invention relates to PU tyre technologies, more particularly to a kind of high performance inflatable bicycle PU tire productions of exempting from Foaming agent.
Background technology
Often by the way of the inner tube of a tyre of inflation, PU foaming tires internal structure is the structure of micropore to tire, is assigned good Damping performance, rebound performance, while having stronger compressive strength, tensile strength and tearing strength；It is extensive abroad Be applied to the fields such as medical treatment, the elderly's vehicle.PU foaming tires can be realized exempting from inflation using the characteristic of itself so that wheel Tire is more preferable using characteristic.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of high performance of proposition exempts from inflation Bicycle PU tire production foaming agents.
To achieve these goals, present invention employs following technical scheme：
One kind is high performance to exempt from inflatable bicycle PU tire production foaming agents, and its raw material is as follows by weight：Component A and B groups Part, component A is 70 parts of PPG according to composition by weight ratio, and 30 parts of high-performance polyalcohol, 12 parts of alcohols chain extender, amine expands 3 parts of chain agent, the first 0.01 part of catalyst, the second 0.01 part of catalyst, the 3rd 0.01 part of catalyst, 0.05 part of foam stabiliser, 0.1 part of emulsifying agent, 0.4 part of water, B component is 90 parts of MDI according to composition by weight ratio.
Preferably, first catalyst is amines catalyst, and second catalyst is modified amine catalyst, described 3rd catalyst is environment-friendly type organo-metallic catalyst.
Preferably, the foam stabiliser is polyether modified siloxane class A foam A stabilizer.
A kind of high performance application method for exempting from inflatable bicycle PU tire production foaming agents in tire production, including Following steps：
S1:According to formula design allocation of raw materials, and the storage tank of cast polyurethane equipment will be respectively squeezed into, and adjust operation Parameter etc. is to be cast；
S2:Mould is fixed on centrifuge, mould is opened and high strength polyester rope is fixed on mould；
S3:Start centrifuge, and set rotary speed, after mould centrifugal speed reaches design requirement, start casting machine Cast knob, PU materials are injected in mould, treat that the reaction solidification of PU materials is completed；
S4:Finished product is removed from the molds, and removes tool, conduit, pruned flash and be finished product.
Preferably, the high strength polyester rope limits tire with wheel rim by being compounded in the both sides of bicycle PU tires Coordinate, prevent tire from coming off.
The a kind of high performance of present invention offer exempts from inflatable bicycle PU tire production foaming agents, by the first catalysis The addition of agent, the second catalyst and the 3rd catalyst and foam stabiliser causes foaming agent in PU tire productions to PU micropores Structure is optimized, and makes microcellular structure more fine and closely woven, is rich in rebound performance, while also suitably improving tear resistance.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with specific embodiment, to this Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not For limiting the present invention.
Embodiment 1
One kind is high performance to exempt from inflatable bicycle PU tire production foaming agents, and its raw material is as follows by weight：Component A and B groups Part, component A is 70 parts of PPG according to composition by weight ratio, and 30 parts of high-performance polyalcohol, 12 parts of alcohols chain extender, amine expands 3 parts of chain agent, the first 0.01 part of catalyst, the second 0.01 part of catalyst, the 3rd 0.01 part of catalyst, 0.05 part of foam stabiliser, 0.1 part of emulsifying agent, 0.4 part of water, B component is 90 parts of MDI according to composition by weight ratio.
First catalyst is amines catalyst, and second catalyst is modified amine catalyst, and the described 3rd urges Agent is environment-friendly type organo-metallic catalyst.The foam stabiliser is polyether modified siloxane class A foam A stabilizer.
A kind of high performance application method for exempting from inflatable bicycle PU tire production foaming agents in tire production, including Following steps：
