Abstract
The invention aims to provide a low-molding-shrinkage resin material composite board which can not generate blockage or adhesion at die molding temperature (generally 80 DEG C and above, and often 100-120 DEG C). The resin material composite board comprises an outer layer, an inner layer and a middle adhesive layer, wherein the outer and inner layers respectively comprise the following components: 60-90 parts of first part (copolymer of vinyl-alpha,beta-unsaturated fatty acids and alpha,beta-unsaturated fatty acid esters), 1-5 parts of second part (terpolymer using alpha-olefin, glycidyl acrylate and vinyl acid ester as monomers) and 15-30 parts of third part (polyethylene). The vinyl-alpha,beta-unsaturated fatty acids account for 10-15% in the first part.
Description
Technical field
The present invention relates to a kind of resin material composite plate.
Background technology
Vinyl-α, the copolymer of β-unrighted acid and carboxylic acid transparency, caking property (such as with metal and glass), the aspect performance such as intensity, pliability, elasticity is good, is widely used in the materials such as building materials, diaphragm.Its shortcoming is that heat resistance is not enough, thereby when mould molding, is easily bonded on roller bearing or forms and block, and the speed of working continuously is exerted an influence, and easily shrink after thermoforming, affects product quality.
Summary of the invention
The object of the invention is at mould molding temperature (generally more than 80 ℃, common is 100 ℃～120 ℃) and can not produce obstruction or bonding, the resin material composite plate that molding shrinkage is low.
The present invention is achieved by the following technical solutions:
Described resin material composite plate, comprises the tack coat at inside and outside two-layer and middle part, and internal layer and skin comprise respectively following component, first: vinyl-α, β-unrighted acid and α, the EVA of β-unsaturated fatty acid ester, 60～90 parts; Second portion: with alhpa olefin, glycidyl acrylate, 1～5 part of the terpolymers that ethene acid esters is monomer; Third part: 15～30 parts of polyethylene.
Further, the vinyl-α in described first, β-unrighted acid proportion is 10%～15%.
Further, vinyl-the α of described first, β-unrighted acid or α, α described in β-unsaturated fatty acid ester, β-unrighted acid is that carbon chain lengths is at the aliphatic acid of 3～7 carbon atoms, the ester carbon chain lengths of its formation is 5～12 carbon atoms, and the degree of polymerization is controlled between 200～500.
Further, each free carbon chain length in described second portion is controlled at 3～7 carbon atoms, and after it forms ester, carbon chain lengths is at 5～12, and the degree of polymerization is controlled between 200～500.
Further, the polyolefin in described third part is the homopolymers of Atactic Polypropylene, propylene and one or more the mixture in LLDPE, and carbon chain lengths is at 3～7 carbon atoms; The degree of polymerization is controlled between 100～200.
Beneficial effect of the present invention illustrates with embodiment testing result in the lump in specific embodiment part.
The specific embodiment
Below in conjunction with the specific embodiment, the present invention is further elaborated:
Umber described in this part unless otherwise indicated, all refers to mass fraction.
The present invention includes following component:
First: vinyl-α, β-unrighted acid and α, the EVA of β-unsaturated fatty acid ester, 60～90 parts; Second portion: with alhpa olefin, glycidyl acrylate, 1～5 part of the terpolymers that ethene acid esters is monomer; Third part: 15～30 parts of polyethylene.
Vinyl-α in described first, β-unrighted acid proportion is 10%～15%.
Vinyl-the α of described first, β-unrighted acid or α, the α described in β-unsaturated fatty acid ester, β-unrighted acid is that carbon chain lengths is at the aliphatic acid of 3～7 carbon atoms.As acrylic acid, methacrylic acid, crotonic acid, maleic acid, anhydrous itaconic acid, while selecting sour under this length of carbochain, product pliability is better, after its formation ester, carbon chain lengths is good at 5～12, esterification selects other acid or alcohol as propionic acid, butyric acid, propyl alcohol, butanols etc., the length of coordinated carbochain; The degree of polymerization is controlled at 200～500 for good.
Each free carbon chain length in described second portion is controlled at 3～7 carbon atoms, and it forms after ester carbon chain lengths and selects other acid or propionic acid, butyric acid, propyl alcohol, butanols etc. for alcohol, the length of coordinated carbochain at 5～12 for good esterification; The degree of polymerization is controlled at 200～500 for good.
Polyolefin in described third part is the homopolymers of Atactic Polypropylene, propylene and one or more the mixture in LLDPE, and carbon chain lengths is at 3～7 carbon atoms; The degree of polymerization is controlled at 100～200 for good.
Manufacture method of the present invention is as follows:
Second portion and the even Hou Zaiyu of third part melting mixing first are mixed.
Moulding can obtain formed body of the present invention in the manner described above, and it can be used as skin material and uses, and inner side is attached with adhesive sticker and is combined with the article that need protection, and outside, as protective layer, can be simple layer, can be also composite bed.
Above-mentioned formed body can also be made multilayer material, and its main application is composite industrial sheet material, prevents from producing bonding with other metals that contact or glass equipment or element etc. under hot environment.Middle part sticks with glue knot, and positive and negative preferably adopts the resin-formed body of different material, in case result of use of certain one side can be changed with another side when bad.
The present invention also can be used as equipment component as bearing etc., but because the lower heavy duty industrial that is not suitable for of the strength of materials, its main purpose is still to prevent bonding, for example, can be used as the conveyer belt of streamline or the surfacing of roller bearing, and it is difficult for producing with the article of surface transport and bonds.
