Description
Technical field
The present invention relates to plastics, in particular to a kind of granular unsaturated polyester UP moulds of high electric strength of injection moldable
Plastics.
Background technique
Unsaturated polyester (UP) UP moulding compound adds mould made of curing agent, filler (frequently with glass fibre) etc. unsaturated polyester (UP)
Plastics.Two class of fragment shape unsaturated polyester die plastic (SMC) and bulk unsaturated polyester die plastic (DMC), product feature are
Mechanical strength height, good stability of the dimension.Various unsaturated polyester (UP)s are to be added each when uncured from low viscosity to highly viscous liquid
Be heating and curing after kind of additive, after solidification rigid or elastic plastics, can be transparent or opaque.Unsaturation is poly-
Glass reinforced plastic is made with glass fiber reinforcement in being mainly used for of ester, and is one of the principal item in reinforced plastics, but existing
Unsaturated polyester (UP) UP moulding compound easily loses flowability in viscosity higher, and curing rate is slow, and mechanical energy can be not good enough.
Summary of the invention
To solve the problems mentioned in the above background technology, the purpose of the present invention is to provide a kind of height of injection moldable
The granular unsaturated polyester UP moulding compound of electrical strength, insulating properties is fine, mechanical strength, and heat distortion temperature is higher.
In order to solve the above technical problems, technical solution provided by the invention are as follows:
The granular unsaturated polyester UP moulding compound of the high electric strength of injection moldable, the height electricity of the injection moldable
The granular unsaturated polyester UP moulding compound of gas intensity is grouped as by following groups by weight percentage: the low insatiable hunger of high relative molecular
With the unsaturated polyester resin A15%-25% of degree；The unsaturated polyester resin B10%- of the lower high degree of unsaturation of molecular mass
15%；Crosslinking agent 0.5%-2%；Reactive plasticizer 1%-3%；Polymerization inhibitor 0.01%-0.02%；Flame-proof filling material 35%-55%；
Release agent 1%-3%；Reinforcing fiber 10%-20%.
As an improvement, the unsaturated polyester resin A and unsaturated polyester resin B are by monounsaturated dicarboxylic acid, insatiable hunger
With line polymer made of binary acid and dihydric alcohol polycondensation.
As an improvement, the crosslinking agent is cumyl peroxide or benzoyl peroxide, the reactive plasticizer is neighbour
Dially phthalate, three allyl rouge of cyanuric acid or maleic anhydride diallyl, the polymerization inhibitor include benzenediol,
Tert-butyl catechol and copper naphthenate, flame-proof filling material are aluminium hydroxide or magnesium hydroxide, and the release agent is talcum powder, cloud
The mixture of female powder, clay and starching clay, the reinforcing fiber are glass fibre, the inorfils such as carbon fiber.
As an improvement, the granular unsaturated polyester UP moulding compound processing temperature of the high electric strength of the injection moldable
It is 80 DEG C -95 DEG C.
The beneficial effects of the present invention are:
Unsaturated polyester resin A and lower molecular weight high insatiable hunger of the present invention by combination higher molecular weight low-unsaturation-degree
With the unsaturated polyester resin B of degree (A be hard resin with B), ensure that in the case where less reactive plasticizer content, it is this
Moulding compound (80 DEG C -95 DEG C) within the scope of processing temperature has viscosity higher not lose mobility again, while guaranteeing moulding compound in mold
In solidify rapidly, the most prominent advantage of the present invention is that resin total amount A+B is very high, and the electrical insulating property of products obtained therefrom is fine, electrical strong
Degree reaches 25MV/m or more, and mechanical strength, heat distortion temperature are higher, and flame retardant property can reach UL94FV0 grades.
