Abstract
The present invention relates to a plastic foaming formula, particularly a novel foaming formula of polypropylene plastic. The foaming formula is characterized by including the following components: by weight, 85%-99.8% of polypropylene plastic, 0.1%-10% of an AC foaming agent, and 0.1%-10% of an N1000 foaming agent. The foaming formula is characterized by including 90% of the polypropylene plastic, 5% of the AC foaming agent, and 5% of the N1000 foaming agent. The main ingredients of the AC foaming agent include azodicarbonamide, a small amount of biurea and calcium carbonate. The AC foaming agent is a commercial product produced by Jiangsu SOPO Chemical Company. The main ingredients of the N1000 foaming agent include poly sodium bicarbonate, a small amount of sodium carbonate and sodium chloride. The N1000 foaming agent is a commercial product produced by Guangzhou Huike Chemical Co., Ltd. The foaming formula has the advantage of stable foaming, no obvious contraction in appearance, light weight, high strength, etc.
Description
Technical field
The present invention relates to a kind of New foam formulation of plastic foamed prescription, particularly a kind of acrylic plastering.
Background technology
The single whipping agent of the general employing of the New foam formulation of acrylic plastering, through stirring, injection moulding, so that plastics form middle pore, thereby reach raising intensity, solve the problem of epitome, adopt white separately whipping agent (N1000, poly-yellow soda ash) to cooperate the raw material foaming, gas forming amount is not enough, weight is too heavy after the foaming, does not reach the expection requirement.And (AC, the Cellmic C 121) whipping agent that adopts independent yellow cooperates the raw material foaming, although gas forming amount is more sufficient, it is yellow that the rear surface of foaming is, and the client can't accept, and its resolvent can't all be discharged product generation pollution.And in order to overcome above-mentioned shortcoming, therefore demand improving the whipping agent prescription of acrylic plastering urgently, with the existing the problems referred to above of the foaming formulation that solves present acrylic plastering.
Summary of the invention
The foaming formulation that the objective of the invention is to solve acrylic plastering in the prior art adopts separately poly-yellow soda ash or the existing the problems referred to above of azodicarbonamide foaming agent, and a kind of New foam formulation of acrylic plastering is provided.The present invention designs the New foam formulation of acrylic plastering, it is characterized in that being comprised of following constituent and weight percent:
Acrylic plastering 85%-99.8%,
AC whipping agent 0.1%-10%,
N1000 whipping agent 0.1%-10%.
It is characterized in that:
Acrylic plastering 90%,
AC whipping agent 5%,
N1000 whipping agent 5%.
AC whipping agent main component Cellmic C 121, a small amount of hydrazo-dicarbonamide and calcium carbonate are the commercially available prod that Suo Pu chemical company in Jiangsu produces, N1000 whipping agent main component is gathered sodium bicarbonate, a small amount of yellow soda ash and sodium-chlor, the commercially available prod that company of Guangzhou brightness section produces.
Advantage of the present invention is that foaming is stable, and outward appearance is without obviously reprinting books in a reduce format, and is lightweight, the intensity advantages of higher.
Below in conjunction with example the present invention is elaborated.
Embodiment
Acrylic plastering is that former factory produces for supplier, and is unmodified, density 0.9-0.92,
AC whipping agent (main component Cellmic C 121, a small amount of hydrazo-dicarbonamide and calcium carbonate) and the N1000 whipping agent (main component is gathered sodium bicarbonate, a small amount of yellow soda ash and sodium-chlor) select whipping agent supplier's commercially available prod, AC such as the production of Jiangsu Suo Pu chemical company, N1000 such as the production of company of Guangzhou brightness section, wherein acrylic plastering is plastic pellet, and AC and N1000 whipping agent are Powdered.AC whipping agent (main component Cellmic C 121, a small amount of hydrazo-dicarbonamide and calcium carbonate) and N1000 whipping agent (main component is gathered sodium bicarbonate, a small amount of yellow soda ash and sodium-chlor).
Embodiment 1
Get 90 kilograms of acrylic plastering, 5 kilograms of AC, 5 kilograms of N1000.Be stirred to evenly, the material that then prepares is delivered in single screw mixing machine, granulation, and 170 ℃ of prilling temperatures, the particle that then will make add injection moulding machine and carry out injection moulding, and the injection molding temperature range of the new prescription of acrylic plastering is 180 ℃.
Embodiment 2
Get 96 kilograms of acrylic plastering, 2 kilograms of AC, 2 kilograms of N1000.Be stirred to evenly, the material that then prepares is delivered in the single screw extrusion machine---granulation, and 180 ℃ of prilling temperatures, the particle that then will make adds the injection moulding machine injection moulding.PP injection molding temperature range is 190 ℃.
Embodiment 3
Get 99 kilograms of acrylic plastering, 0.3 kilogram of AC, 0.3 kilogram of N1000.Be stirred to evenly, the material that then prepares is delivered in single screw mixing machine, granulation, and 200 ℃ of prilling temperatures, the particle that then will make adds the injection moulding machine injection moulding.PP injection molding temperature range is 250 ℃.
Should allocate under (1) normal temperature, normal pressure during stirring, (2) clean out a mixing bowl before stirring blowing.
The granulation problem is difficult for too high,
Shooting Technique effect comparison before and after the acrylic plastering foaming formulation:
