The novel masson pine wood plywood form can be repeatedly used for more than 70 times, so that a great quantity of wood and chemical materials can be saved. The masson pine wood plywood form has good economic and social benefits.
Description
Technical field
The utility model belongs to the construction material field, specifically refers to a kind of degreased masson pine Plywood template that has premium properties, is used for the concreting engineering.
Background technology
The veneer cement formwork of producing take masson pine as raw material is widely used at the realm of building construction.The service condition very severe of cement formwork needs to come into contacts with moisture, concrete, sandstone, high and low temperature and other harsh climate for a long time, so to its performance, especially its abrasion resistance, bonding strength and water-fast, heat resistance is had higher requirement.The plywood form of producing take masson pine as raw material at present, the adhesive of use mainly contains Lauxite, phenolic resins resin and melamine resin three major types.Lauxite is water-fast due to it, heat resistance and bonding strength all relatively poor, the plywood form take it as adhesive production can only be reused 5-8 time usually, cause timber and industrial chemicals consumption, the waste very large.The normal plywood template of producing take phenolic resins, melamine resin as adhesive, although have good water resistance and bonding strength, but the abrasion resistance on their surfaces is not high, making it reuse number of times is greatly affected, and because product surface is more coarse, needing can not be used for building of one-time formed clear-water concrete engineering.Some plywood form surface label one deck impregnated paper, improved to a certain extent planeness and the abrasion resistance of product surface, but still can not reach the requirement of high-wearing feature.A large amount of concreting requirement of engineering one-time-concreting moulding is arranged at present, and do not need to remake secondary, whitewash for three times, this has bright and clean, even curface with regard to the concrete work that requires to build moulding, and above-mentioned plywood form all is difficult to satisfy its requirement.
The utility model content
The technical problems to be solved in the utility model is in the defective that exists aspect production technology and product quality, to propose a kind of novel Pinus massoniana Plywood template with premium properties for existing Pinus massoniana Plywood template.
In order to achieve the above object, the technical scheme that provides of the utility model is:
Described a kind of pinus massoniana plywood form is characterized in that, described template comprises the two-layer wearing composite material layer in up and down, is located at some layers of Masson pine timber veneer between the two-layer wearing composite material layer in up and down; Described wearing composite material layer is successively by one deck tego film paper, layer of metal net and two-layer melamine resin adehsive film paper form, wherein, described tego film paper contacts with the Masson pine timber veneer, and melamine resin adehsive film paper is the external surface of template.
Wherein, described Masson pine timber veneer thickness is 1.5-2.5mm, is preferably 2mm.In described some layers of Masson pine timber veneer, a part of Masson pine timber veneer surface scribbles adhesive, another part Masson pine timber veneer surface is not coated with adhesive, the Masson pine timber veneer that scribbles adhesive is alternate stacked with the Masson pine timber veneer that is not coated with adhesive, and the machine direction of adjacent two layers Masson pine timber veneer is mutually vertical.The coating weight of described Masson pine timber veneer surface adhesive is 400-420g/m
2Described adhesive is phenol-formaldehyde resin modified.In described template, the Masson pine timber veneer number of plies is odd number.The thickness of described wire lath is 0.8-1.2mm, is preferably 1mm, and its mesh size is 70-90 orders, is preferably 80 orders.
In addition, described template forms by hot-press gluing; Wherein, hot pressing temperature is 140-150 ℃, and the hot pressing compressive load per unit area is 1.5-1.8MPa, and calculate by every millimeter thickness pressurization 1-1.2min pressing time.
The utility model is described in further detail below in conjunction with principle, technique and advantage:
High-performance Masson pine timber plywood form of the present utility model is by the slab that is comprised of wearing composite material and treated plate of Pinus massoniana being carried out hot-press gluing, above-mentioned two kinds of materials are closely linked, more a kind of sheet material that obtains behind the jagsaw limit.
Described composite abrasion resistance material is to be that 80 order thickness are wire lath and one deck tego film paper of 1mm left and right by two layers of melamine resin adehsive film paper, one deck mesh, by a kind of slim composite material that hot-press gluing forms, the back side of high-abrasive material is made the sand hair and is processed.
Described plate of Pinus massoniana refers to process by the masson pine log being carried out rotary-cut a kind of slim board-like material that obtains, about its thickness 2mm.Described processing to plate of Pinus massoniana refers to the ungrease treatment to plate of Pinus massoniana, the dry processing and the gluing processing.Ungrease treatment refers to remove part resin in plate of Pinus massoniana by certain method; The dry processing refers to that veneer is dried to moisture content 8%-12% by dry kiln or drier; Gluing is processed and is referred to adopt automatic double surface gluer to dried veneer surface-coated adhesive, and adhesive is phenol-formaldehyde resin modified, and glue-spread is 400-420g/m
2The number of plies of plate of Pinus massoniana is odd number, and its number of plies is determined by product thickness.A part in plate of Pinus massoniana scribbles adhesive, and a part is not coated with adhesive, blanket glued veneer and the not alternate configuration of blanket glued veneer, and the machine direction of adjacent layer veneer is mutually vertical.
Described hot-press gluing refers to slab is become an integral body by the hot press hot-press gluing.Hot-press equipment is multi-daylight press, and hot pressing temperature is 140-150 ℃, and the hot pressing compressive load per unit area is 1.5-1.8MPa, presses every millimeter thickness pressurization 1-1.2min of product pressing time and calculates.Described saw limit refers to the burr plate after hot-forming is pressed the breadth specification of national Specification, saws by edging and trimming saw and is cut into the four orthogonal stock boards in limit.
The utility model in the defective that exists aspect production technology and product quality, has proposed a kind of novel Masson pine timber plywood form with premium properties for existing Pinus massoniana Plywood template.This plywood template can not come unglued through boiling more than 10h continuously, the be up to state standards index of a class veneer of regulation of bonding strength, anti-wear performance is less than 80mg/100r, reuse number of times more than 70 times, can save a large amount of timber and industrial chemicals, have good economical, societal benefits.
