Abstract

The invention discloses an HIPS composite board. In the composite board, the first layer is a transparent high-gloss HIPS layer; the second layer is a blending layer made from HIPS and a titanium dioxide color master batch; and the third layer is a blending alloy layer made from PS/PE. The composite board is prepared by a method that the raw materials are dried and then simultaneously extruded into the same distributor through three extruders, and after being extruded out through a T-shaped die head, the raw materials are flattened and molded. The invention has the advantages that the composite board not only can effectively stop the dissolution and corrosion effects of a foaming agent HCFC-141b used as a heat insulating material of refrigerators (ice chests) on the HIPS used as a liner material, but also has the function of resisting stress cracking caused by vegetable oil.

Description

HIPS composite plate and preparation method thereof
Technical field
The present invention relates to a kind of HIPS composite plate and preparation method thereof, particularly relate to a kind of employing co-extrusion mode and prepare the method that is applicable to refrigerator (cabinet) inner bag HIPS composite plate.
Background technology
In the prior art with impact resistant polystyrene (High Impact Polystyrene, be called for short HIPS) be that refrigerator (cabinet) inner bag of matrix is by two big class materials manufacturings, one class is the common sheet material of HIPS, this class sheet material is in the refrigeration plant of blowing agent and cold-producing medium applicable to freon and hydrocarbon, because the harm of freon mainly is to destroy the ozone layer of atmosphere, therefore all do not allow in the production of carrying out this class material from countries in the world in 2000, hydrocarbon is inflammable simultaneously, explosive, manufacturer need increase a large amount of fire prevention during use, the antiknock device investment.Second class is the HIPS composite board, be generally used for HCFC-141b is blowing agent, with HFC-134a is in the refrigeration plant of cold-producing medium, this blowing agent and cold-producing medium do not destroy ozone in the atmosphere and nonflammable basically, but it causes traditional HIPS inner bag deliquescing, bubbles, erodes away the cavity, thereby influences the use of HIPS in this field.
Summary of the invention
One of purpose of the present invention provides a kind of HIPS composite plate.
HIPS composite plate, ground floor are impact resistant polystyrene (HIPS) layer, by weight percentage, account for the 2-20% of HIPS composite plate total amount; The second layer is the blended layer that impact strength impact resistant polystyrene (HIPS), titanium dioxide color masterbatch are formed, and organizes percentage by weight, and the titanium dioxide color masterbatch accounts for the 2-10% of blended layer total amount, and surplus is HIPS; The 3rd layer is the blend alloy layer that impact resistant polystyrene/polyethylene (PS/PE) is formed, and by weight percentage, accounts for the 5-20% of HIPS composite plate total amount
2, two of the purpose of the present invention preparation methods that provide above-mentioned HIPS composite plate comprise the steps:
A, at first the raw material with above-mentioned every laminate material stirs in mixed-hopper separately, simultaneously the drying of carrying out 1-7 hour in temperature is 60-90 ℃ scope is handled, wherein an extruding machine body temperature is set in 200-240 ℃ of scope, to be expressed into distributor as ground floor behind the HIPS fusion plastification, second extruding machine body temperature is set in 200-240 ℃ of scope, to be expressed in the distributor as the second layer behind HIPS and the titanium dioxide color masterbatch fusion plastification, the 3rd extruding machine body temperature is set at 200-240 ℃, will be expressed into behind the PS/PE fusion plastification in the distributor as the 3rd layer;
After b, above-mentioned sheet material raw material are squeezed in the same distributor by extruding machine, are extruded into through T shape die head and prolong in the pressure roller equipment, being extruded to shape forms three-layer co-extruded sheet material;
C, the above-mentioned sheet material of preparing the 3rd laminar surface use the electronics shock machine in the 800-1000A sided corona treatment.
Described ground floor HIPS layer adopts transparent high glaze class high impact polystyrene.
Advantage of the present invention:
The HIPS composite plate can effectively stop the dissolution and corrosion effects of the blowing agent H CFC-141b of refrigerator (cabinet) heat-barrier material to liner material HIPS.Simultaneously,, have high gloss characteristics, can resist the vegetable oil stress cracking, as sunflower oil, salad oil because the ground floor of co-extrusion HIPS composite plate is transparent HIPS material.
The specific embodiment
Embodiment 1
A, at first the raw material with above-mentioned every laminate material stirs in mixed-hopper separately, simultaneously the drying of carrying out 4 hours in temperature is 70 ℃ scope is handled, wherein an extruding machine body temperature is set in 200-240 ℃ of scope, will be expressed into distributor behind the transparent high glaze HIPS fusion plastification as ground floor; Second extruding machine body temperature is set in 200-240 ℃ of scope, by weight percentage, the titanium dioxide color masterbatch accounted for 4%, HIPS is expressed in the distributor as the second layer behind the proportioning fusion plastification of surplus; The 3rd extruding machine body temperature is set at 200-240 ℃; To be expressed into behind the PS/PE fusion plastification in the distributor as the 3rd layer;
After b, above-mentioned sheet material raw material are squeezed in the same distributor by extruding machine, are extruded into through T shape die head and prolong in the pressure roller equipment, being extruded to shape forms three-layer co-extruded sheet material;
C, the above-mentioned sheet material of preparing the 3rd laminar surface use the electronics shock machine in the 800-1000A sided corona treatment;
D, the above-mentioned sheet material of preparing promptly become the sheet material of required size requirement through side cut, again through the extremely horizontal cutting knife of traction after cutting.
