Abstract
A production process of a pasty synthetic resin material. The production process of the pasty synthetic resin material comprises steps of prefabrication of material A and material B, and mixing of the material A and the material B in a ratio of 1:0.5-0.8 during usage. The prefabrication of the material A comprises steps of: stirring and mixing 100-120 weight parts of epoxy resin, 30-35 weight parts of polysulfide rubber, 25-30 weight parts of glass bead, 35-45 weight parts of alumina and 15-20 weight parts of silica in a vacuum environment at 80-100 DEG C; and then filling and sealing. The prefabrication of the material B comprises steps of: stirring and mixing 50-60 weight parts of polyether amine, 10-15 weight parts of plasticizer, 10-15 weight parts of glass bead, 20-25 weight parts of alumina, 8-10 weight parts of silica at room temperature; and then filling and sealing. The pasty synthetic resin material has advantages of good toughness, high hardness, stable dimension and good temperature resistance.
Description
Technical field
The present invention relates to a kind of production technique of pasty state synthetic resins material, this pasty state synthetic resins material can be used for making benchmark model, cubing, model configuration, casts products such as model.
Background technology
But machining resin template; Another name is substitute materials for wood, cubing material; The resin template can be processed with CNC, also can carve and modify fluffing in the time of can wood grain, engraving not being arranged as timber by hand; And have better hardness, dimensional stability and temperature tolerance, therefore be widely used in production of products such as vehicle mould, cubing, ship model, die for shoe-sole, product model.
But initial machining resin template is to produce with unsaturated polyester, promptly in unsaturated polyester, adds glass microsphere powder, adds solidifying agent again; Extract the air of the inside out, its curing is formed, along with the continuous development of industry; The resin template of working it out with unsaturated polyester; Shortcoming can't satisfy market demands because of its non-refractory, volatility, hardness be low etc., and for overcoming above-mentioned shortcoming, selecting Polyurethane or epoxy resin at present for use is the resin template of main material production; It is all better relatively in physical propertys such as toughness, hardness, dimensional stability, temperature tolerances, but still need improve.
Summary of the invention
The objective of the invention is deficiency, a kind of good toughness, hardness height, dimensional stability and the good pasty state synthetic resins material of temperature tolerance are provided to prior art.
The object of the invention is realized through following technical scheme:
A kind of production technique of pasty state synthetic resins material comprises the prefabricated of A material and B material and in use A material and B material stirring and evenly mixing is made pasty state synthetic resins material that the blending ratio of A material and B material is 1:0.5-0.8;
It is prefabricated that A expects: with the glass microballon that gathers sulphur glue, 25-30 weight part of 100-120 parts by weight of epoxy resin, 30-35 weight part, the aluminum oxide of 35-45 weight part, silicon-dioxide stirring and evenly mixing, loading sealing then under 80-100 ℃ vacuum environment of 15-20 weight part;
B material prefabricated: with the silicon-dioxide of the aluminum oxide of the glass microballon of the softening agent of the polyetheramine of 50-60 weight part, 10-15 weight part, 10-15 weight part, 20-25 weight part, 8-10 weight part stirring and evenly mixing, filling and sealing then at normal temperatures.
The present invention has following beneficial effect:
When A material and the mixed pasty state synthetic resins material that gets of B material; Polyetheramine can and gather sulphur glue generation crosslinking reaction with epoxy resin; Make pasty state synthetic resins crosslinking curing after accomplishing Modelling; But the pasty state synthetic resins after the curing is the machining solid resin, and advantage such as have that good toughness, hardness are high, dimensional stability and temperature tolerance are good can be widely used in making benchmark model, cubing, model configuration, cast product such as model.
Compare with the solid resin template; Pasty state synthetic resins material is more convenient for analogue formation, when the deviation mistake appears in Modelling, can in time repair, and helps control and practices thrift cost; Pasty state synthetic resins material can be used for machine or manual application in addition; Operability is good, is applicable to the making of different in nature model, can reduce material cost greatly.
