Abstract
The present invention discloses wear-resisting polyester resin used for forming products made from glass reinforced plastics. The resin is a compound prepared from multi-element mixed resin matrix, wear-resisting stuffing composition and an assistant, and the products of the resin have the advantages of good wear resistance and high comprehensive mechanical performance and simultaneously reserve the construction manufacturability of common unsaturated polyester resin. The present invention is suitable for the occasions where high wear resistance is needed, such as slide ways, slide carriages, pipes for conveying liquid containing particles, etc.
Description
The present invention relates to the wear-resistant type resin combination of a kind of glass fiber reinforced plastics product moulding with the unsaturated polyester resin type.
The glass reinforced plastic moulding is a lot of with the unsaturated polyester resin type, and its performance also more difference, and because of its construction technology is simple, convenient formation is widely used at present.But at some special occasions, for example: carry the slideway slide carriage of powder material, conveying contains the pipeline of particle-liquid etc., usually because of the wear resistance deficiency, causes wearing and tearing, influences work-ing life.Someone once attempted to start with from synthetic technology of resins and material prescription and improved the wear resistance of resin, but because the characteristic of high molecular synthetic material, it produces effects not quite.Also the someone adopts and add wear resistant filler in resin, improves the product wear resistance, but after directly adding filler, makes resin system become fragile, and easily spot corrosion is peeled off under intensive impacts.
The objective of the invention is at existing vibrin wear resistance deficiency, and a kind of resin of number of different types and wear-resisting type polyester resin composition that wear resistant filler combined and had common unsaturated polyester resin processing performance of adopting is provided.
For achieving the above object, the technical scheme of the present invention's proposition is: a kind of composition that adopts poly-blended type resin matrix, wear resistant filler composition and the suspendible auxiliary formation of optimizing proportioning after screening.Starting material component of the present invention is (consumption is parts by weight): metaphenylene resin 100, vinyl ester resin 60-100, adipic acid type resin 2-15, silicon carbide 1.6-8, glass-cermic powder 3-16, active silica 0.5-2.5, methyl-silicone oil 0.0025-0.02.
Optimal seeking of raw and processed materials compositional range of the present invention is (parts by weight): metaphenylene resin 100, vinyl ester resin 60-80, adipic acid type resin 2-10, silicon carbide 1.6-4.8, glass-cermic powder 3.2-9.6, active silica 0.8-1.9, methyl-silicone oil 0.003-0.01.
Starting material best composition of the present invention is (parts by weight): metaphenylene resin 100, vinyl ester resin 79.85, adipic acid type resin 4.99, silicon carbide 3.7, glass-cermic powder 7.4, active silica 0.92, methyl-silicone oil 0.0046.
The size range for preparing filler composition in the starting material of the present invention is: silicon carbide 200-500 μ m, glass-cermic powder 20-80 μ m.
Each raw-material main effect is: adopt splendid metaphenylene resin of construction technology performance and the vinyl ester resin with excellent mechanical performances, and add an amount of adipic acid type resin with flexibility function group and carry out poly-blendedly, make the matrix resin of excellent performance; Adopt the varigrained filler of polycomponent,, have good abrasion resistance and excellent comprehensive mechanical properties to guarantee resin through the cementability of coupling agent treatment raising with resin matrix; Adopt active silica to do suspensoid, stop the filler precipitation, satisfy the requirement of user the rosin products shelf lives.
The present invention compared with prior art has following advantage:
1, adopt poly-blended resin matrix, material source is wide, and the adaptation of product is strong, and each component resin is brought into play characteristics separately, still has good comprehensive mechanical properties after adding filler.
2, adopt polycomponent wear resistant filler, both guaranteed to have very high wear resistance also to guarantee bonding strength with resin matrix simultaneously through coupling agent treatment.
3, adopt suspensoid to stop the filler precipitation to guarantee that product has the long shelf lives, can adopt batch production to produce and guarantee consistency of product, the operation when simplifying construction.
The present invention is further elaborated below in conjunction with embodiment:
Present embodiment is for adopting the interrupter method unsaturated polyester resin production system with 10M dilution still, and raw-material type and consumption see Table one, table two.Table one
