| Summary: | 碩士 === 中國文化大學 === 造紙印刷研究所 === 85 === With the coming of electric information time,the demand and
development of printed circuit board is increasing year by
year.At the same time,the request of laminates is much higher
than before.With the small sized and high density packed of
electric product,the generation of heat in the board is larger
than before.
Three kinds of base paper were made under different formula
conditions,and six different quantity contained Aluminum
hydroxide fillers were added into p apers.The most proper base
paper was evaluated by the comparison of tensile st rength,
tearing strength,bursting strength,porosity,and paper
smoothness.Compa red the difference between the non-coated
paper and the coated paper.The heat resistant property can be
testified by using DSC and TGA,and the surface stru cture
pattern of paper was observed by using SEM.
From the result of experiment,it was found that (the pulp
formula of NBKP:LB KP=40:60),10% inorganic fillers was added
into composite base paper,which have better physical properties
than the others.After pigments coating on this base paper,it
still has excellent physical strength.In the thermal property,
the hea t resistant extent has improved by the function of
Aluminum hydroxide pigment.
