Abstract
The invention discloses wooden penholder sealing primer which is characterized in that the sealing primer is composed of polyvinyl acetate emulsion, plasticizing agent, alkali N-hydroxymethyl acrylamide, acetone and ethyl acetate, and the weight percentages of the ingredients are as follow: polyvinyl acetate emulsion 60-75%, plasticizing agent 1-5%, alkali N-hydroxymethyl acrylamide1-0.8%, acetone10-20% and ethyl acetate10-20%. The wooden penholder bottom sealing primer is high in solid content and low in viscidity and is quick to dry(in 5 seconds) and convenient to use. The wooden penholder bottom sealing primer has obvious effect during the coating process in penholder manufacturing; the wooden penholder sealing primer is the first domestically and is internationally advanced in performance index in all aspects.
Description
Technical field:
The invention belongs to the technical field of coating, relate in particular to a kind of bottom closing paint for wood pen holder of the external coating of industries such as pencil manufacturing.
Background technology:
Domestic wooden penholder (as pencil and cosmetic pencil manufacturing) adopts lacquer primer and finish paint as the external coating material on the technology of external coating substantially at present.This traditional technology adopts the above lacquering technique in six roads to carry out application for increasing the paint film plumpness mostly.Therefore have not only that coating process is numerous and diverse, the surperficial paint film plumpness of penholder is poor, cost height and working efficiency be low, and obvious defects is paint film adhesion poor (QFH hundred lattice method of testing secondarys are following)!
Summary of the invention:
The object of the present invention is to provide a kind of bottom closing paint for wood pen holder, it is poor that it can solve paint film adhesion, penholder surface paint film plumpness difference and the numerous and diverse deficiency of coating process.
Technical scheme of the present invention is achieved in that a kind of bottom closing paint for wood pen holder, it is characterized in that: described bottom closing paint is made up of polyvinyl acetate emulsion, softening agent, N hydroxymethyl acrylamide alkali, acetone, vinyl acetic monomer, and their weight percent is,
Polyvinyl acetate emulsion 60-75%
Softening agent 1-5%
N hydroxymethyl acrylamide 0.1-0.8%
Acetone 10-20%
Vinyl acetic monomer 10-20%.
A kind of bottom closing paint for wood pen holder is characterized in that: described bottom closing paint is made up of polyvinyl acetate emulsion, tensio-active agent, softening agent, N hydroxymethyl acrylamide alkali, acetone, vinyl acetic monomer, and their weight percent is,
Polyvinyl acetate emulsion 62-68%
Tensio-active agent 0.5-1%
Softening agent 2-3%
N hydroxymethyl acrylamide 0.2-0.5%
Acetone 12-18%
Vinyl acetic monomer 12-18%.
Bottom closing paint for wood pen holder of the present invention is a reversed-phase emulsion, have solid content height, viscosity low, fast dried (surface drying time 5 seconds), easy construction, be applied in penholder and make on the coating process, obtained significant effect, belong to domestic initiation, and performance index aspect has in every respect reached leading in the world; Concrete beneficial effect compared with prior art is:
1, the sticking power of paint film and timber is improved greatly, by bringing up to (QFH hundred lattice testing method) more than the one-level below the secondary that traditional primary coat reached;
2, the japanning operation can reduce to four roads by six roads of original traditional technology, raise the efficiency reduce cost in, also significantly improved the plumpness of paint film;
3, timber is applied widely, on different wood kind such as linden, Xi Damu, poplar, whitewood splendid adhesion effect is arranged all;
4, environment protecting is remarkable, and VOC (organic volatile) is low, reaches the standard of the EN71-9 of European Union;
5, this priming paint is compared with the neat solvent system priming paint that adopts in the world, characteristics such as having high solids content, fast do, cost is low, be coated on the film that can form complete densification behind the penholder, reduce the infiltration of finish paint to lumber fibre, strengthen the degree of staining and the colorimetric purity of finish paint, thereby reach the effect that reduces the japanning operation.Its indicators of overall performance has surpassed the standard that neat solvent system priming paint that Japan adopted is reached.The present invention can use and promotes in high-grade pencil cosmetic pencil manufacturing, this product also may extend to the surface lacquer technology of conventional wooden woodwork industry, replace traditional solvent-borne type wood lacquer primary coat, thereby reach the effect that improves paint film adhesion, minimizing japanning operation, saves cost, raising environmental requirement, will have good society and economic benefit.
Embodiment:
Below the invention will be further described and provide embodiment.
The present invention is a kind of bottom closing paint for wood pen holder, it is characterized in that: described bottom closing paint is made up of polyvinyl acetate emulsion, softening agent, N hydroxymethyl acrylamide alkali, acetone, vinyl acetic monomer, their weight percent is, polyvinyl acetate emulsion 60-75%, softening agent 1-5%, N hydroxymethyl acrylamide 0.1-0.8%, acetone 10-20%, vinyl acetic monomer 10-20%; In order to make effect more quite a lot of, adopt during concrete enforcement, a kind of bottom closing paint for wood pen holder is characterized in that: described bottom closing paint is made up of polyvinyl acetate emulsion, tensio-active agent, softening agent, N hydroxymethyl acrylamide alkali, acetone, vinyl acetic monomer, and their weight percent is, polyvinyl acetate emulsion 62-68%, tensio-active agent 0.5-1%, softening agent 2-3%, N hydroxymethyl acrylamide 0.2-0.5%, acetone 12-18%, vinyl acetic monomer 12-18%.Polyvinyl acetate emulsion, softening agent, N hydroxymethyl acrylamide alkali, acetone, vinyl acetic monomer that the present invention uses are common commercially available chemical feedstocks, polyvinyl acetate emulsion wherein has splendid sticking power to wood surface, therefore select the high polyvinyl acetate emulsion that contains admittedly as main base-material, the Vinyl Acetate Copolymer solid content of polyvinyl acetate emulsion is at least 60% in the enforcement; Being added with of tensio-active agent helps improve the effect of impregnation may of coating to base material, introduce active self-crosslinking methylol gene in the enforcement and also help to improve the sticking power of paint film timber and finish paint, the tensio-active agent of present embodiment is commercially available polyethers dimethyl siloxane solution, the solid Sha's product of moral, model is TEGO 590; Softening agent can improve the snappiness of paint film, effectively fills the multiporous fiber structure of timber, and the softening agent of present embodiment is the two isopropylformic acid fat of 2.2.4-trimethylammonium 1.3-pentanediol; Acetone is the quick-drying solvent can influence the rate of drying of paint film as main solvent again when guaranteeing lower working viscosity as few as possible, thereby improves the production efficiency of use.
