For technique as shown in Figure 1 it is found that in the present invention, the property of main chemical constituent is as follows：Polyacrylate is readily soluble
In acetone, ethyl acetate, benzene and dichloroethanes, and it is not soluble in water.Due to the compliance of its macromolecular chain, their vitrifying temperature
Spend (Tg) it is relatively low and different with carbon atom number and its branched situation of ester group, when carbon atom number be 8 when it is minimum.In same carbon original
In the ester group of subnumber, branched person's glass transition temperature is higher.Polyacrylate can form good luster and water-fast film, and bonding is secured,
It is not easy to peel off, flexible and flexible at room temperature, good weatherability, but tensile strength is not high.Flawless finish coating can be done.Polypropylene
Acid esters is adhesive, can be used as pressure-sensitive adhesive and thermal sensitivity adhesive.Since its ageing-resistant performance is good, pollution is bonded
Small, easy to use, yield increases very fast.In terms of textile industry, polyacrylate can be used for sizing, stamp and final finishing,
The textile arranged with it, well-pressed beauty, good hand touch；It also acts as non-woven fabrics and flocking, the adhesive for planting wool product.It is poly-
Acrylate can be used for tan leather, can increase gloss, water proofing property and the elasticity of leather.In addition, polyurethane full name is poly- amino
Formic acid esters is the general designation containing the macromolecular compound for repeating carbamate groups on main chain.It is by organic diisocyanate
Ester or polyisocyanates are formed with dihydroxy or polyol addition polymerization.
Wherein, glass fiber powder is that the continuous glass fibre precursor that will specially draw is sieved through being chopped, grinding, as
Filling reinforcing material is widely used in various thermosetting resins and thermoplastic resin.Glass fiber powder is packing material to improve
Article Stiffness Determination, compression strength reduce shrink of product rate, wear scar width, abrasion, production cost.Glass fiber powder also known as grinds glass
Glass fiber, abbreviation glass powder, English name milledglasspowder, milledglassfiber are to pass through glass fiber precursor
It is chopped, crushes, milling, (drying), sorting.
