Background technology
Fiberglass scientific name fibre reinforced plastics are commonly called as FRP (Fiber Reinforced Plastics), i.e. fiber reinforcement
Composite plastic.It is divided into glass fiber reinforced composite plastics (GFRP), fibre reinforced composite plastic according to the fiber difference of use
(CFRP), boron fibre enhancing composite plastic etc..It is using glass fibre and its product (glass cloth, band, felt, yarn etc.) as enhancing
Material makees a kind of composite material of basis material with synthetic resin.Fibre reinforced composites are by reinforcing fiber and matrix group
At.The diameter very little of fiber (or whisker), generally at 10 μm hereinafter, defect is less and smaller, breaking strain is about 3/1000ths
It is fragile material within ten, easy damaged, fracture and is corroded.Matrix for fiber, intensity, modulus will it is low very
It is more, but big strain can be withstood, often there is viscoplasticity and elastoplasticity, be toughness material.
Due to its with high-strength light, the excellent performances such as corrosion-resistant, good electrical property, hot property is good, designability is good and
It is applied by wide hair.Since the fiberglass specification of batch production limits, polylith is generally required in practical applications and is spliced；This is just
It needs to use adhesive；But adhesive generally existing used at present cannot take into account transparent and light stabilized seal agent performance,
Even if taking into account, performance is ideal not enough.Adhesive strength is relatively low, and long-time water, which impregnates, is easy cracking.

500 parts of 3.0 parts, 16.5 parts of hexadecanol, 9 parts of diglycol, 1 part of ultra-violet absorber and styrene are prepared.
The preparation method of the smooth stabilized seal agent unsaturated polyester resin：
A. the phthalic anhydride of institute's quantity, cis-butenedioic anhydride, hexadecanol and diglycol are put into reaction kettle, are passed through inert gas, added
Heat heating；
B. when temperature is up to 138 DEG C -142 DEG C, stop heating, keep the temperature 2-3 hours；
C. continue to be heated to 190 DEG C -200 DEG C, when test acidity is 45mgKOH/g, stop heating, keep the temperature 2-3 hours；
D. 75 DEG C are cooled to, the ultra-violet absorber of the amount is added and styrene and is sufficiently stirred, it is steady to obtain the light
Determine sealant unsaturated polyester resin.
Preferably, specific as follows：
A. homogenizer is added in hot water in the octyl dodecanol myristinate of institute's quantity, monoglyceride and triethanolamine
The addition of uniformly obtained mixed solution, the water is octyl dodecanol myristinate, monoglyceride and triethanolamine summation
Twice；
B. by gained mixed solution, light stabilized seal agent unsaturated polyester resin, cyclohexanone peroxide, cycloalkanes in step A
Sour cobalt and styrene paraffin liquid are uniformly mixed, and are cured under high-temperature low-pressure, and the smooth stabilized seal agent is made.
Preferably, the hot water that hot water described in step A is 60 DEG C -80 DEG C, mixing speed is 1800 revs/min.

It is 45mgKOH/g, viscosity 69pa.s with polyester resin acid value, and especially prepares.The light stabilized seal agent unsaturated polyester (UP) tree
Not only transparency is good, hard, light stabilized seal agent is good for fat；Especially with cyclohexanone peroxide, cobalt naphthenate, styrene paraffin
After the additive compatibilities such as liquid, octyl dodecanol myristinate, monoglyceride and triethanolamine, embodies excellent water resistance and glue
Tie power.
Wherein, cyclohexanone peroxide as initiator can generate free radicals and cause the double bond in unsaturated polyester resin with
Crosslinking agent is copolymerized, is crosslinked and cures.Cobalt naphthenate length is used in combination with peroxyester, but due to its intrinsic certain face
Color and use less；The unsaturated polyester resin prepared in the present invention has the agent of light stabilized seal but has certain face
Color subsequently with octyl dodecanol myristinate, monoglyceride association reaction, is being transparent, and shear strength is very good.
