The unsaturated polyester resin is modified unsaturated polyester resin where the dicyclopentadiene can be thickened or the thickenable dicyclopentadiene modified unsaturated polyester resin and the thickenable isophthalic or the o-benzene typed polyester resin are mixed in a weight proportion of 9:1 to 9. After being hot press molded, the combination of the invention has the characteristics of high surface hardness, low shrinking percentage and high mechanical strength, which can be used for being pressed and molded into wall plates of train coach bodies, sanitary ware and insulating barriers.
Description
Technical field
The invention belongs to dicyclic pentylene modified unsaturated polyester resin is the glass fibre reinforced mould plastic composition of matrix resin, relates to a kind of dicyclopentadiene modified unsaturated polyester resin glass fiber reinforcement molding composition.The unsaturated polyester resin glass fibre reinforced mould plastic composition product of this method preparation is applicable to fields such as the wallboard, sanitary ware, insulating barrier of compression moulding train casing.
Background technology
In the existing unsaturated polyester glass fiber sheet molding compound (being called for short SMC), the prescription of unsaturated polyester resin glass fibre reinforced mould plastic generally by the aluminium hydroxide of unsaturated polyester resin, polystyrene, particle diameter 1～23 μ m or/and the non-twist fibre glass roving of alkali-free of lime carbonate, length 25～50mm, peroxidized t-butyl perbenzoate, Zinic stearas, pigment paste, activated magnesia etc. form.Fields such as that the product that makes is widely used in is electric, transport facility, building, sanitary ware.But used unsaturated polyester resin was thickening O-phthalic acid type (being called for short adjacent benzene type) unsaturated polyester resin and m-phthalic acid type (abbreviation metaphenylene) unsaturated polyester resin during prescription was formed.Shrinking percentage height after this resinoid solidifies causes the surface hardness of goods low simultaneously, and the mechanical property of goods is relatively poor.The shrinking percentage of common SMC unsaturated polyester resin glass fibre reinforced mould plastic is 0.1～0.5%, and Barcol hardness is lower, below 48, and flexural strength is less than 180MPa.
Reclaim in the byproduct of dicyclopentadiene (dicyclopentadiene is called for short DCPD) for raw gasline steam cracking production ethylene process and make (C5 fraction), price is low.Owing to have performances such as good dry air, erosion resistance, low contractions as starting material synthetic resin, so become the problem that many in recent years production of resins producer competitively develops as starting material production unsaturated polyester resin with dicyclopentadiene with dicyclopentadiene.
The Yang Kai of South China Science ﹠ Engineering University etc. has inquired into various influence factors of dicyclic pentylene modified unsaturated polyester resin synthetic and main technique condition thereof; This resin does not have thickening properties as the matrix resin of hand paste glass reinforced plastic.
China Patent No. ZL96119856.7 disclosed " a kind of preparation method of dicyclic pentylene modified unsaturated polyester resin " provides a kind of method for preparing dicyclic pentylene modified unsaturated polyester resin (DCPD modification UPR) (UPR is a unsaturated polyester resin).The resin that this method makes is water-fast, resistance to chemical corrosion good, but does not possess thickening properties.
Chinese patent application 200510026882.X disclosed " a kind of preparation method of dicyclic pentylene modified unsaturated polyester resin " provides the preparation method of a kind of dicyclic pentylene modified unsaturated polyester resin (DCPD modification UPR).The advantage of the resin that this method makes is that goods have more excellent thermotolerance, is higher than the state of the art of currently available products.But this resin is also stuck with paste the matrix resin of glass reinforced plastic as hand, do not have thickening properties equally.
