Abstract
The invention belongs to the manufacturing technology of composite materials, and relates to a powder sizing agent for an RTM composite material preformed body and a preparation method thereof. The powder sizing agent is formed by mixing a component A and a component B, wherein the component A is one of solid aromatic amine, solid acid anhydride, crystal cyanate ester and bismaleimide monomer resin; the component B is one of resinoid bismaleimide monomer resin/ allylbisphenol A/ allylphenol copolymer, solid epoxy resin and solid cyanate resin prepolymer; and the component A accounts for 10 to 90 percent of the weight of the powder sizing agent. The preparation method comprises the following steps: preparation of the component A, preparation of the component B, and mixing. The method can prevent the powder sizing agent from hardening under room temperature long-term storage condition, and improves the pre-sizing effect of fabrics.
Description
Technical field
The invention belongs to manufacture technology of composite material, relate to a kind of RTM composite material preformed body powder sizing agent and preparation method thereof.
Background technology
Setting agent is the important process material of fibre reinforced composites liquid molding process.Early stage setting agent is that the resin dissolves that will have suitable viscosity and softening point forms setting agent solution in solvent, then setting agent solution is brushed or is sprayed on the purpose that reaches typing on the enhancing body fabric.The shortcoming of solution setting agent is: the first, setting agent resin uniformly penetrating is in the fabric fibre bundle rather than mainly be coated in fabric face, influence typing effect; The second, need to use a large amount of solvents, not only improved cost, and caused pollution environment.Three, production efficiency is low.In order to protect environment and to reduce the pre-setting cost, improve typing effect and efficient, the dry method powder sizing agent has appearred in the manufacturing of RTM composite.At present, a kind of powder sizing agent PR500 is arranged abroad, its prescription and preparation method are all underground.Its shortcoming is: meeting be hardened and can't normally be used under the long time stored condition of room temperature.Someone adds inorganic powder and prevents that powder sizing agent from hardening in setting agent, if but these inorganic powders content in setting agent is too high, and these inorganic powders will influence performance of composites, not prevent the purpose that hardens if inorganic powder has again very little.
Summary of the invention
The objective of the invention is: propose a kind of RTM composite material preformed body powder sizing agent and preparation method thereof, this powder sizing agent can prevent to harden under the long time stored condition of room temperature, to improve the pre-setting effect of fabric.
Technical scheme of the present invention is: a kind of RTM composite material preformed body powder sizing agent, it is characterized in that, it is mixed by first component and second component and forms, the first component be solid aromatic family amine, solid acid anhydrides, lenticular cyanate and span monomer resin one of them; The second component be resinoid span monomer resin/allyl bisphenol-A/chavicol copolymer, solid epoxy or solid cyanate ester resin prepolymer one of them; 8～90% of first ingredients constitute powder sizing agent weight, surplus is the second component.
The preparation method of powder sizing agent as described above is characterized in that, the step of preparation is as follows:
1, the preparation of first component; To be crushed to 100～300 purpose granularities in first component raw material adding air-flow disintegrating machine or the mechanical crusher;
2, the preparation of second component; With the granularity that is crushed to 50～100 in second component raw material adding air-flow disintegrating machine, freezing crusher or the mechanical crusher;
3, mix; Take by weighing first component and second component after the pulverizing in proportion, join and mix 1～10 minute in the airslide disintegrating mill, perhaps join to mix in the mechanical mixture device and got final product in 10～60 minutes.
Advantage of the present invention is: can prevent that powder sizing agent from hardening under the long time stored condition of room temperature, improved the pre-setting effect of fabric.Compare with the solution setting agent, pre-setting is effective, and cost is low, non-environmental-pollution, production efficiency height.
The specific embodiment
Below the present invention is described in further details.A kind of RTM composite material preformed body powder sizing agent is characterized in that, it is mixed by first component and second component and forms, the first component be solid aromatic family amine, solid acid anhydrides, lenticular cyanate and span monomer resin one of them; The second component be resinoid span monomer resin/allyl bisphenol-A/chavicol copolymer, solid epoxy or solid cyanate ester resin prepolymer one of them; 8～90% of first ingredients constitute powder sizing agent weight, surplus is the second component.
The preparation method of powder sizing agent as described above is characterized in that, the step of preparation is as follows:
1, the preparation of first component; To be crushed to 100～300 purpose granularities in first component raw material adding air-flow disintegrating machine or the mechanical crusher;
2, the preparation of second component; With the granularity that is crushed to 50～100 in second component raw material adding air-flow disintegrating machine, freezing crusher or the mechanical crusher;
3, mix; Take by weighing first component and second component after the pulverizing in proportion, join and mix 1～10 minute in the airslide disintegrating mill, perhaps join to mix in the mechanical mixture device and got final product in 10～60 minutes.
Basic functional principle of the present invention is: the material of first component for not having viscosity, and the second component is the component with viscosity.After the pulverizing of first, second component, the granularity of second component is greater than the first component, make the first component in mixed process, stick to the outer surface of second component, thereby the first component particles that makes the second component particles with viscosity do not had viscosity is isolated, and makes the second component particles with viscosity can mutual bonding caking in storage process.But, such powder sizing agent in use, first and second liang of components or second component be fusion or softening under setting process temperature and operation pressure, permeates or sticks on the reinforcing material, thereby reach the purpose of typing.
